ContentsThis issue of Helmet covers more than the usual dose of safety related articles. The entire issue addresses various interesting areas right from occupational stress management to prevention of accidents while working at heights.
Being released during the hottest month of the year there are a couple of articles that cover heat related stress and how to safeguard oneself as well as the work force from such harsh natural elements. Apart from many thought provoking articles, this issue also covers and compiles significant EHS related events that have happened across the globe from each IC.
Hope that the articles are not only motivating, but also help in implementation of the good practices shared so that every project site becomes a safe work environment.
Happy reading

NEBOSH Accreditation for L&T’s Leadership Development Academy (LDA)
Academy (LDA), Lonavala. A tutorial team comprising of Mr.M Kamarajan, Mr.Josy John, Mr.Varatharajan Janardhanam, Mr.S.Selvaganapathy, Mr. Shailendra Kumar, Mr. Mathivanan Palaniappan, Mr. M. Nachiappan, Mr.R.V.Sudhakar, Mr. Krishna Nirmalya Sen; senior EHS executives from various ICs of L&T attended the meeting.
The objective of the meeting was to standardize the delivery of the course, to increase the effectiveness of the course and to achieve the overall objective of creating ‘Change agents’ who will inculcate a positive EHS culture in their respective place of work after attending this intensive culture building course. Mr. Neville Lobo, Vice President, Corporate HR and Director of LDA, set the context. He said that NEBOSH was the first step to address the critical aspect of creating a culture of Health, Safety, Security and Environment (HSSE) in the company. Mr. M Kamarajan, Head, HSE, B&F, who has delivered
National Examination Board for Occupational Safety & Health (NEBOSH), UK accredited L&T’s Leadership Development Academy (LDA) at Lonavala for delivering their International General Certificate (IGC) Course at a function organised in L&T’s Headquarters, Chennai on March 4, 2013. The formal agreement to this effect was signed by Ms. Teresa Budworth, Chief Executive, NEBOSH and Mr. Neville Lobo, Vice President, Corporate HR & Director, LDA, L&T in the presence of Mr. S.N. Subrahmanyan, Member of the Board and Sr. Executive Vice President (Infrastructure & Construction), L&T and Mr. Stuart Naylor, International Manager, NEBOSH. A formal accreditation certificate was also presented to Mr. S.N. Subrahmanyan by Ms. Teresa.
In order to launch the first batch of this course, which is scheduled during 15th April to 25th April at Chennai, L&T internal Tutors’ workshop was held on Friday, 22nd March at Leadership Development
4 HELMET Jan - Mar 2013
more than 30 batches of NEBOSH IGC courses, conducted the workshop. Some of the decisions that were taken during the meeting are:
y Safety Pledge will be administered at the beginning of all the training programs (in future) along with L&T Anthem; a pocket size multipurpose card will be printed and handed over to all the participants with the pledge printed on it.
y Attractive safety promotional materials shall be considered for publication in ATL (home page), which will be periodically changed
y HSSE module, (which is currently under development) will be launched in the ATL web site and will be used for giving safety induction to all levels of staff
y Participants of the NEBOSH course will be requested to share the knowledge gained during the program in their place of work to as many staff members as possible; this process will be facilitated by the concerned EHS head of the IC; peer review (of the participants) will be conducted (after 3 to 6 months of their participation in the NEBOSH program) to understand whether their approach to EHS has changed for the better.
After a lot of deliberations, it was decided to prepare a world-class course material (developed completely in-house) for the course and to use the NEBOSH training as a vehicle to bring a cultural transformation within the organization.

Message from B&F IC
It was a great opportunity to look at the current EHS
management system and the best practices that are
currently being implemented in the B&F sites after 18
years, since I was involved in the formation of the EHS
department during 1980s and maintaining/ monitoring the
EHS performance till 1995.
It is a pleasure to see that many of the fundamental
principles that were introduced (and practiced) in the
yester-years are being nurtured even today and a strong
growth in many best operational practices, particularly the
five critical SOPs (Lift Shaft & Floor Opening Protection,
Working on Peripheral Platforms, Builders Hoist Operation,
Temporary Electrical Distribution System & Barricades for
Excavation) and the related audits around those.
Safety Trophy Scheme (based on risk indices), The Helmet
magazine, Safety Month celebration are some of the
classic initiatives that were introduced many years before,
which have stood the test of time and is being practiced
even today, although it has gone through some cosmetic
changes!
Well, as is a normal practice, based on a gap analysis that
was performed after extensive discussions with various
levels of people across the length and breadth of our work
places, some of the initiatives that have been introduced /
being introduced are discussed below:
EHS Management System:
Scope of the management system is extended to the IC as a
whole, instead of restricting it the EHS function alone; in-line
with this requirement, Mr. K. Kannan (VP & Head for IT&IS
BU) was chosen to be the Management Representative
(MR). All the procedures are being modified with a single
line objective of bringing a positive EHS culture among all
the employees.
Competence Building Workshop:
One of the first and foremost need was to empower and
motivate the EHS team members to be self-starters/ self-
motivated; a well-designed Competence Building Workshop
(a one-day interactive program) has been designed and has
Buildings & Factories 5HELMET Jan - Mar 2013
6 HELMET Jan - Mar 2013 Buildings & Factories
been completed in all the Clusters; this will be continued
once in three months in all the clusters to serve as an
opportunity to rejuvenate them and to facilitate them to
function in a more focussed manner.
Pro-active EHS Performance Monitoring System:
EHS performance measurement was construed to be
the accident/ incident ratings only and there was a lack
of measuring the proactive EHS performance. Based
on this, an extensive and comprehensive proactive EHS
performance measures have been designed and launched
since April 2013, using which, individual EHS performance
of all the employees (staff members) at site is being tracked
down. This will help the management to recognize the top
performers on a monthly basis and to counsel the poor
performers so that they can be facilitated to perform better
during the subsequent months.
EHS Suggestion Scheme & Nearmiss Reporting:
Serious focus is being given to collect and capture all the
minor injury and no injury incidents, which ultimately lead
to serious injury incidents, if not taken seriously; all levels
of employees are being encouraged to report the hazards/
unsafe conditions at the work place either through the
existing suggestion scheme or by calling the safety engineers
over phone. Every deviation from the existing practice is
being looked at as an “opportunity to learn”, rather than
a violation being committed by an individual (and hence a
need to punish someone).
All the deviations are only symptoms and root cause analysis
(RCA) is being encouraged to find out the actual failure that
allowed the symptom to exist so that a permanent solution
can be worked out. All the EHS personnel are being groomed
to diagnose the causes of failures/ deviations (through RCA
techniques) so that they can prescribe correct medicines
(solutions), rather than treating the symptoms alone or
being policemen, (catching people doing wrong things).
Safety Improvement Slip
All the site engineers and managers have been provided
with a safety improvement slip (booklet) and have been
requested to issue it to all those who are not doing what
they are supposed to be doing in their respective area of
work towards EHS requirements; this has brought in a
culture of EHS being monitored/ nurtured by one and all
– not just by the EHS team members alone! “No blame”
culture is being brought in/ promoted in all the incident
investigations.
EHS Leadership Program
As the readers of “The Helmet” are aware, a two days’
training program on “Construction Safety” is being
organized for all the staff members for the past many years.
However, senior staff members (above the level of M2) are
excluded from this training program and hence a one day
workshop on “EHS Leadership” has been designed and in
fact is scheduled in the training calendar, released by HR
department. This is likely to create ownership / involvement of
project directors / managers and construction managers.
One day Workshop on Internal Audit Techniques
In addition, refresher training was organized recently for all
the internal EHS auditors to facilitate them to conduct audit
in a more comprehensive manner and to leave behind (with
the auditee) a set of “opportunity for improvement” rather
than a set of “Non-Compliances”.
One final, but an important cultural change being
promoted is to integrate the EHS requirements in the way
we do business in our IC. For ex: in all the training programs
(technical, behavioural, functional and managerial) being
organized by HR department, EHS requirements are
being built-in. Similarly, it is proposed to embed the EHS
requirements, while procuring materials / machinery / men,
right at the source, so that there is no need for ‘tinkering’ it
to make it safer (alright), after it is procured/ hired.
Well, we have set an ambitious goal for ourselves for the
year 2013-14, with a fond hope that all employees will
cooperate with us in all earnest in this drive. With folded
hands, all the readers of “The Helmet” (from B&F IC) are
requested to join this exciting journey and be a part of
this ongoing drive to eradicate the menace of incidents /
accidents v/ dangerous occurrences.

Construction Safety
Safety and Me
Buildings & Factories
Safety is not a tick-box for various programs or actions taken (in various checklists), but it is to develop a proactive mindset. Being reactive is responding to a situation where a failure has occurred and the fallout has impacted on the operations. The enormity of the fallout can be as small as losing a few minutes of productivity to huge measurable losses including human lives. A pro-active approach to the management of safety, both on the job and off the job, supports the business and ensures that the interests of all stakeholders are protected.
A term that is commonly used across all sectors (but not fully understood by many) is ‘Safety Culture’. Safety culture is a sub-set of the overall culture of the organisation and will vary with the industry or activity. The safety performance of an organisation depends largely on the safety culture of the organisation. Safety culture comprises of the shared values, perceptions, attitudes, behaviour and a combination of knowledge, skills, aptitudes and the collective experience among the employees, who form the organisation.
Culture develops from the combined experience of the people within the organisation, not necessarily planned in advance and need not be the culture the organisation desires to have. The uniqueness of safety culture is that it is not stagnant; there are a whole lot of factors that influence changes to keep the momentum going. It (safety culture) reacts to experience, changes in the organisation’s philosophy and the impact of external and internal stakeholders. Technological advances resulting in process modifications and elimination of human interface are also critical to safety culture. In other words, the organization should keep a vigil on the likely changes in the safety culture due to the arrival of new employees, technological advances, process modifications and the influence of the stockholders and establish a course correction (in the culture) if found necessary.
The perception of safety will vary with people groups based on ethnicity, access to information, education and experience and bias towards recognizing safety comes first in real terms and not just remain as a
10 HELMET Jan - Mar 2013
slogan within the organisation. Organisations with diverse ethnic and language groups forming part of its workforce have a greater challenge in moulding a common safety culture or in other words to have everyone read off the same page when it comes to safety. This challenge is real and the management has to take steps to counter this aspect of managing the workforce in a manner which will be acceptable to all who are employed. Safety culture is shaped by and has a direct relation to the individual, task and the organisation and these can have much variance.
Organisations are run by people and hence their psychological, behavioral and situational factors mould the work culture which the organisation will possess and this in turn will influence or create the safety culture of the organisation. Within the overall culture, a variety of sub-cultures will exist in the organisation depending on the nature of the business whether it is in a high risk sector like nuclear, oil/gas or an everyday office environment where the severity of the outcome of an unwanted incident will be lower.
The origin of the term Safety Culture is from the report published in 1987 by OECD Nuclear Agency (INSAG, 1988) on the 1986 Chernobyl disaster. A definition of safety culture widely used is ‘...the product of individual and group values, attitudes, competencies, and patterns of behaviour that determine the commitment to, and the style and proficiency of, an organisation’s Health & Safety programs. Organisations with a positive safety culture are characterised by communications founded on mutual trust, by shared perceptions
of the importance of safety, and by confidence in the efficacy of preventative measures’. – The Advisory Committee for Safety in Nuclear Installations, subsequently adopted by the UK Health and Safety Executive.
Developing a culture with safety as the core value is essential for a business to survive, since the key stakeholders are the individuals, organisation and the state as a regulatory body representing the interests of the larger society and everybody will have a win-win situation.
Management systems are much talked about and scrupulously followed in certain aspects like procurement, production and quality. Adopting the same approach to managing the safety aspects of the personnel and assets ensures that the delivery of quality products and services are ensured. Identifying the gaps in safety in the human and material capital employed in the organisation will be the first step towards building a safety culture.
Questions to ponder
What is the organisation culture at my workplace?
Why is the safety culture (within my workplace and beyond) not at par with best in its class?
What will be my contribution to enhancing safety culture?

Occupational Stress Management
Stress exists from time immemorial. Today with
modernisation, we have a mechanised world having
the sedentary, highly competitive jobs, alcohol abuse,
excessive smoking, imbalanced diet and total lack
of exercise, which has totally changed our lifestyle.
Stress is the greatest enemy of your health if allowed
to overcome you. Yet it can be a friend if managed
properly.
What is the stress?
Stress in Physics is defined as a “Force that deforms
bodies”. In human begins, stress does deform the
body, in the long run, in the form of stress related
diseases.
Human Responses to stress
The human body responds to stress with certain
temporary physiological changes. This response
depends on the vulnerability of each individual’s
system and personality. If a person’s gastro-intestinal
system is sensitive, he would have either hyperacidity,
loose motions or constipation. A particular stress may
cause no harm to one person,while being a high stress
to another.
Occupational stressors
A: Environmental (Physical) stressors
The environmental stresses are heat, light, noise,
chemicals and ergonomic stress. These are relatively
easy to manage by modification in the work
environment or re-design of work place.
B: Psychosocial Stressors
These are more difficult to manage as they cause
internal stress on the body. Psychosocial stress arises
from an individual’s inability to adapt to change.
Due to these higher responsibilities, white collared
employee’s experiences greater psychosocial stress.
Women employees are put to higher stress because
of their dual roles as bread winner and house wife.
With globalisation comes high competitiveness, high
targets and demands, inadequate qualifications,
limited growth opportunities, impersonal
relationships, which increase the stress.
How to identify stress effects?
Signs of stress effects
1. PHYSICAL: Intense exertion, manual labor, lack of sleep, travel
2. CHEMICAL: Drugs, alcohol, caffeine, nicotine and environmental pollutants such as cleaning chemicals or pesticides
3. MENTAL: Perfectionism, worry, anxiety, long work hours
4. EMOTIONAL: Anger, guilt, loneliness, sadness, fear
5. NUTRITIONAL: Food allergies, vitamin and mineral deficiency
Buildings & Factories
12 HELMET Jan - Mar 2013
6. TRAUMATIC: Injuries or burns, surgery, illness, infections, extreme temperatures
7. PSYCHO-SPIRITUAL: Troubled relationships, financial or career pressures, challenges with life goals, spiritual alignment and general state of happiness
Stress Related Diseases
Stress, if not managed properly can lead to p r e c i p i t a t i o n of following diseases or their aggravation if already existing.
Peptic ulcer, u l c e r a t i v e colitis, coronary artery disease, cerebro-vascular disease, Hypertension, diabetes, headaches/migraine, back pain, pain in the neck, bronchial asthma, psychosomatic diseases and sexual problems.
Management of Occupational Stress
y Plan your work well with proper time management.
y Don’t hide weakness and inadequacies,try to overcome them
y Avoid postponing things you are supposed to do now, a c c u m u l a t e d work can cause the stress
y Set reasonable/realistic goals
y A v o i d procrastination
y Set boundaries
y Listen to your favorite songs
y Place your stressors if you can ( e.g. m a r r i a g e ,
divorce, changing a house or changing a job)
y Don’t compromise your values/beliefs
y Do regular physical andyoga exercises
y Do regular relaxation exercises like breathing and guide imagery
y Make time for recreation and take vacations
y Take active part in family matters and spend time with family
y Maintain a proper balanced diet. Avoid excessive smoking and alcohol consumption.
y 30 to 40 minutes of aerobic exercises daily helps provide relaxation
y Have adequate rest and sleep
y Periodical medical check-up, helps early detection and corrective action against stress related diseases
y The key word is Balance
y Maintian balance with a POSITIVE ATTITUDE to mange the Stress

Answers for Heat Stress Q&A
1. The heat stress index is the evaporative heat loss required to maintain body temperature divided by the maximum available heat loss through evaporation. If the required evaporative heat loss to maintain the correct body temperature is more than the maximum available heat loss through evaporation (which depends mostly on the body’s ability to perspire)
The correct solution is C.
2. Acclimatization is the process of gradually getting used to a much warmer environment.
Metabolism generates heat internally in the body.
Some heat is transferred through radiant energy.
Convection is the transfer of heat through direct contact with fluids such as air or water.
The correct solution is D.
3. Convection = 0.65V0.6 (T-95) is the equation to be used;
Where,
V = air velocity (in fpm)
T= temperature (oF) in Fahrenheit
Air velocity is given as 20 miles per hour; this has to be converted to foot per minute (fpm)
20 mph = 20X5280/60 fpm (1 mile = 5280 feet; 1 hour = 60 min)
= 1760 fpm
Convection = 0.65 (1760)0.6(85-95) = - 576 BTU/HR
The correct solution is B.
4. A person is probably becoming overstressed when their sustained heart rate exceeds(180– their age).180 – 35 = 145 bpm (beats per minute)The correct solution is C.
5. Radiant heat load is calculated using the following equation:
R = 15(tw – 95)
Where,
R = radiant heat load (BTU/hour)
tw = radiant temperature of surrounding objects (F)
R = 15(101 – 95) = 90 BTU/hour
The correct solution is D.
6. Conduction is the heat transfer through solid objects.
Convection is the heat transfer through contact with moving fluids. When we are dealing with heat stress, the moving fluid is usually the atmospheric air.
Evaporation is the heat lost through water (sweat) evaporating from the skin.
Radiant heat transfer occurs through infrared radiation between objects.
The man feels the cold from direct contact between the woollen socks and the floor.
Hence the correct solution is A.
7. Thermal stress is the heat load placed on the body. This can also be called as heat stress.Thermal strain is the body’s response to thermal stress. Heat syncope is the reduction of blood to the brain.Hence the correct solution is D.
8. The WBGT under a solar load = 0.7WBT + 0.2GT + 0.1 DBT
WBGT = 0.7(75) + 0.2(84) + 0.1(82) = 77.5
The correct solution is B.
PS: For cloudy days, DBT is ignored in the equation; it would be revised as: WBGT = 0.7 WB + 0.3 GT
9. The psychrometric chart provides a graphical relationship for water vapor pressure, dry bulb temperature, wet bulb temperature, relative humidity, and dew point.
Hence the correct solution is D.
10. 37oC - normal oral temperature (core body temperature)35oC – Body starts shivering
33oC - Severe hypothermia sets-in, below this temperature
31oC – Person becomes unconsciousness, blood pressure is difficult to obtain, shivering stops
Hence, the correct solution is C.

Operation of Mobile Cranes Near Energized Transmitters or Electric Power Lines
It is recognized that operating mobile cranes where they can become electrified from electric power lines and transmitter towers is an extremely hazardous practice. It is advisable to perform the work to ensure that there is no possibility of the crane, load line, or load becoming a conductive path.
Operating Near a Transmitter Tower
Before initiating work near a transmitter tower(e.g., radio, microwave), where an electrical charge can be induced in the equipment or materials being handled, the transmitter shall be de-energized or tests shall be made to determine if electrical charge is induced on the crane. If an electrical charge is induced and the transmitter cannot be de-energized, the following shall be done:
a. The equipment shall be provided with an electrical ground directly to the upper rotating structure supporting the boom.
b. Ground jumper cables shall be attached to the materials that are being handled.
c. Combustible and flammable materials shall be removed from the immediate area before operations.
Operating Near Electric Power Lines (See Figure 1)
Any overhead wire shall be considered to be an energized line unless and until the owner of the line or the electrical utility authorities indicate that it is not an energized line. Do not rely on the coverings of wires for protection.
The following four conditions must be considered when operating a mobile crane near electric power lines:
a. Power lines de-energized and grounded.
b. Power lines energized, crane operating less than the erected/fully extended boom length away.
c. Power lines energized, crane within prohibited zone.
d. Crane in transit, no load and boom lowered.
Crane Operation Near De-energized and Grounded Electric Power Lines
This describes the preferred condition under which the operation can be performed safely. The hazard of injury or death due to electrocution can been removed.
Buildings & Factories
The following steps shall be taken to ensure that de-energization of the power lines has occurred:
a. The Power Company or owner of the power lines shall de-energize the lines.
b. The lines shall be visibly grounded to avoid electrical feedback and appropriately marked at the job-site location.
15HELMET Jan - Mar 2013
16 HELMET Jan - Mar 2013
c. A qualified representative of the owner of the lines or a designated representative of the electrical utility shall be on site to verify that steps (a) and (b) have been completed and that the lines are not energized.
d. If cage-type boom guards, insulating links, or other proximity warning devices are used on cranes, such devices shall not be used as a substitute for requirements of ‘working near energized power lines’. If such devices are used, due to the lethal nature of electrical hazards and to lessen the potential of false security, the crane operator, crew, and load handling personnel shall receive instructions and have an understanding of:
(1) The electrical hazard involved,
(2) Operating conditions for the devices,
(3) Limitations of such devices, and
(4) Testing requirements prescribed by the device manufacturer.
Power lines energized, crane operating within the erected/ fully extended boom length of the prohibited zone (see Figure 2).
a. An on site meeting between project management and a qualified representative of the owner of the power lines or a designated representative of the electrical utility shall take place to establish the procedures to safely complete the operations.
b. The specified clearance between the power lines and the crane, load line, and load shall be maintained at all times as specified in Table 1 and shown in Figure 3.
c. Load control, when required, shall utilize tag lines of a non conductive type. (Are commended choice
a. When operating near high-voltage power lines

d. A qualified signaller, whose sole responsibility is to verify that the required clearance is maintained, shall be in constant contact with the crane operator.
e. No one shall be permitted to touch the crane or the load unless the signaller indicates it is safe to do so.
f. Operation of boom and load over electric power lines is extremely dangerous due to limited perception of distance and multiple contact points as viewed from the position of the operator and/or position of the signaller. The operator should avoid operating the crane,with or without a load, in this area.
g. The horizontal and vertical distance of movement of long span lines due to the wind shall be added to the minimum clearance distance as specified in Table 1. A qualified representative of the owner of the power lines or a designated representative of the electrical utility shall be consulted for specific distances.
h. A qualified person should attach devices such as ribbons, balls, etc., to the power lines to improve visibility, or equivalent means employed to aid in location of the Danger Zone.
i. If cage-type boom guards, insulating links, or other proximity warning devices are used on cranes, such devices shall not be used as a substitute for requirements of ‘working near energized power lines’. If such devices are used, due to the lethal nature of electrical hazards and to lessen the potential of false security, the crane operator, crew, and load handling personnel shall receive instructions and have an understanding of the following:
(1) The electrical hazard involved
(2) Operating conditions for the devices
(3) Limitations of such devices

(4) Testing requirements prescribed by the device manufacturer.
Crane operations within the prohibited zone and the power lines are energized.
CAUTION: Working in the prohibited zone with power lines energized requires very disciplined and extraordinary safety precautions, including direct involvement and support from the electric utility organization.
a. Before such operations take place, a qualified person responsible for crane operations and a qualified representative of the utility or an engineer qualified in power line transmission, after visiting the site together, shall determine whether operating the crane within the Prohibited Zone is the most feasible way to complete the job. Both persons shall set minimum required clearances and procedures for safe operations. These operations shall be under their supervision. Before crane operations within the Prohibited Zone, the following may be required:
(1) Crane/load grounding to a neutral line by the utility.
(2) Electrical system protective devices that automatically re-energize the circuit after a power line contact occurrence blocked or disengaged to inhibit this function.
(3) Insulated barriers, which are neither a part of, nor an attachment to the crane and which will not allow contact between the energized electric power lines and the crane, load lines, or load.
(4) Non conductive barricades to restrict access to the crane work area.
b. Load control, when required, shall utilize tag lines of a non conductive type. (Are commended choice for a non conductive tag line is dry rope made of polypropylene or polyethylene fibre.)
c. A qualified signaller, whose sole responsibility is to verify that the established clearances are maintained, shall be in constant contact with the crane operator.
d. The person responsible for the operation shall alert and warn the crane operator and all persons working around or near the crane about hazard of electrocution or serious injury and instruct those persons on how to avoid the hazard.
e. All non-essential personnel shall be removed from the crane work area.
f. No one shall be permitted to touch the crane or the load unless the signaller indicates it is safe to do so.
g. If cage-type boom guards, insulating links, or other proximity warning devices are used on cranes, such devices shall not be used as a substitute for requirements for working near energized power lines. If such devices are used, due to the lethal nature of electrical hazards and to lessen the potential of false security, the crane operator, crew, and load handling personnel shall receive instructions and have an understanding of the following:
(1) The electrical hazard involved
(2) Operating conditions for the devices
(3) Limitations of such devices
(4) Testing requirements prescribed by the device manufacturer.
Crane in transit with no load and boom lowered
a. Cranes in transit with no load and boom lowered shall maintain the minimum clearance as specified in Table 1(b).
b. If during transit, there is a reasonable possibility of getting near a power line, a persons hall be assigned to observe the clearance and give warning before the crane approaches the minimum required clearance. It is important that this person not be distracted or assigned other duties while observing power line clearance.
c. When planning transit of the crane, the effect of speed and terrain on the boom and crane movement shall be considered.

20 - TIPS to reduce Pollution
1. Go paperless, Save environment: Sure you can’t stop advertisement leaflets coming in to your mail box (shouldn’t there be an environmental law to ban this practice, or at least, be made mandatory to use recycled paper?) but, you can control the statements, updates and notices which you get from your financial institutions.
Select ‘paperless’ as the mode of communication. Most people support this. It’s high time that all govt. agencies implement this too.
2. Stop using bottled water: This may be very hard for many, I understand. If it’s not that hard for you, start using re-usable materials and fill it up every time.
3. Stop smoking: Smoking creates pollution inside of your body and for the people around you. Even after hours of smoking, your kids can be recipients of harmful effects of your nicotine consumption.
“The pollution caused by cigarettes does not stop in our bodies or the air around us; it also affects the land we live on and the water that we drink. Millions of cigarette butts are discarded on to the ground every day“.
4. Use less electricity: There are various options to save on electricity. The easiest of all is to use a fan instead of an AC, if you can. Air drying clothes, letting sunlight come inside the home during winter and blocking it during summer are other easy options to try out at your home.
5. Use less gas: Bike to work, car-pooling are the easier options you can try. There are various other effective line.
6. Recycle: Don’t just throw your old electronics and batteries to trash. Make use of local free recycling facilities. Dispose your plastic containers as well by separating them out from normal trash.
7. Use reusable shopping bags: They are made of cloth and need cleaning once a week. This helps in eliminating a lot of plastics from our life.
8. Buy fresh local produce: Whenever you have option to buy from farmer’s market or local grocers, give it a preference. Processed goods take a lot of energy, first for processing part and later, the fuel consumption involved in transportation.
9. Save water: Sweet water is a scarce resource and it’s being depleted at a greater pace than earth is replenishing it. There are various ways to save water in everyday use from fixing leaky outlets to adjusting the timers on sprinklers.
10. Use emails and e-Greetings: Unless you are already using it, what’s preventing you from going ‘e’ route? Apart from being environment friendly, it also reduces effort required to pass your message across.
11. Use ceramic cups: Instead of plastic, paper or Styrofoam, the ceramic cups can be used over and over. This reduces the impact on the environment and on your budget.
12. Print less: Unless it’s absolutely necessary to print, refrain
from doing so. When you do have to print, consider printing on both sides of the paper.
13. Refuse receipts: I understand this is just a small savings of paper use here, but every little bit helps! Use credit/debit card to pay at the stores and decline the printing of the receipt. Your purchase is documented in your statements any way. If required for taxes, you can easily access the information.
14. Reuse and re-purpose: Whenever possible, re-use the containers, cartons and envelops. Oh, your tooth-brush as well! For cleaning sports shoes
15. Use energy-efficient bulbs: In the long run they save a lot of money and energy. Best are the LED bulbs, even fluorescent light bulbs consume 1/3rd (or lesser) of the energy of incandescent light bulbs.
16. Use clothes more than paper: Reduce paper usage by using cloths to wipe your hands or the things you normally wipe with paper towels.
17. Use microwave: Numerous dishes can be cooked in microwave. Use microwave more often to reduce your carbon footprints.
18. Leak proof your home: Ensure you are not losing warmth or cool through leakages, by having your home properly insulated and window and door seals checked. By doing so, you are saving energy and money.
19. Replace air filters: AC air filters for your home and car, if replaced regularly, can save a lot of energy which in turn can save you money.
20. Consume less: This is for your financial good as well. Live simple, use your furniture and clothes until they can’t be used any more. If possible, check out used items on Craigslist or garage sales.

Load Testing of Gantry CranesA gantry crane is particularly well suited for lifting and moving heavy objects in limited work area like PC yard and fabrication yard. We do use many gantry cranes with varying capacities ranging from 10 ton to 120 tons at our operations. Most of the incidents involving gantry cranes such as toppling, derailment,collision and overrun can be avoided by ensuring the fitness of the crane and track through pre-deployment, periodical inspections and strictly adhering to safe operating procedures.
Load testing of Gantry crane is therefore a critical requirement to ensure the fitness of crane. Load test shall be carried out as per the guidelines given below:
y All the gantry cranes shall be load tested during any of the below mentioned situations whichever occurs earlier:
¾ New Gantry Crane installation at site
¾ Relocation from one site to another site
¾ Working at a site for 12 months
y After installation and before commissioning, Gantry cranes shall not be used for any other activity without load testing other than for handling / arranging the loads for load testing.
y Load testing to be carried out at 110% of rated capacity of the crane.
y Tandem load testing to be carried out only if the job requirement is such that two cranes need to be used at the same time. In all other cases, the load testing to be carried out only for individual crane.
y Deflection to be checked with reference to the piano wire tied to both ends of the girder.
y Test to be conducted as per latest guidelines of IS807 and
IS3177 standards. Maximum deflection to be measured at rated load only. The maximum allowed deflection is 1/750th of span when measured in mm.
y Load to be kept in suspended condition for 10 minutes before checking the deflection in the center of the main girder.
y Load testing to be carried out with known weights, with pre-cast elements and additional concrete blocks cast for this purpose. Preferably, weights to be painted on loads for future references and to have a better clarity.
y During load testing, lifting hook to be kept at the center of the transverse travel on the main girder and load to be cleared from ground for about one feet.
y After the measurement of deflection at the rated capacity, the overloading of 10% to be added, further load testing to check the structural stability and to compensate possible jerk loads.
y With the complete load (i.e, with 10% extra load) crane needs to be marched for about a distance of 5 metres to check the stability of structures and long travel brakes.
y Record of deflection and tested procedure to be maintained immediately after completion of the testing.
y The complete load testing to be witnessed by P&M in-charge, EHS in-charge, Precast Yard in-charge and a third party competent authority.
Certificate of test should also be taken from the third party competent person (third party) as per the statutory requirements.

In industries, Power Transformers are used for distributing electrical power to the shops and mills. One power transformer may not be sufficient to distribute power as per the load. Therefore, two transformers of same rating (Ex:1.6MVA for both the Transformers) are made parallel / synchronized to distribute the required Power to the consumers. During the parallel operation / synchronization of the Power Transformers, many fatalities have occurred in the past due to non-adherence of the conditions for synchronization. After the procurement of the Power Transformers they need to be checked for all the parameters mentioned in the brochure that accompanies the equipment.
The following conditions need to be ensured before connecting both the transformers to the power supply source:
1. V – Secondary terminal voltages should be same.
2. I – Percentage impedance must be same.
3. P – Polarities must be same.
4. S – Phase sequence must be same.
5. Group – The vector groups must be same.
Generally, the first four parameters (i.e. V, I, P and S) are ensured, but the vector groups are overlooked. The vector group plays a vital role for safe synchronization.
Example: The following diagrams indicate the phase angles of the transformers considering the example of clock.
Transformers-1 Transformer-2
DY4 DY11
*[D-Delta (Primary), Y-Star (Secondary)]
Since there is a phase angle difference of 210° and if the phases of transformer-1 is connected with the corresponding phases of transformer-2 with a phase angle difference of 210° there will be a huge flashover causing death to the people working nearby with damage to both the transformers. Therefore, attention is to be given during the synchronizing of power transformers for the above five conditions.

Safety vs. Productivity: Friend or FOE?
Friends of productivity can be the foes of safety and it reminds them to put Safety First. There are five foes of Safety, such as, Focus, Fatigue, Familiarity and Faulty Communication. In order to achieve high levels of Safety, Quality and Productivity, workers must have a conducive working environment.
The 5S Method of Improvement - Enhancing Safety, Productivity and Culture:
5S is a foundation for disciplined actions. It builds a culture of continuous improvement.
5S consists of:
y Sorting :- Sorting the activities aim to eliminate unnecessary items from the work area and to perform an initial cleaning.
y Simplifying:- This involves simplifying the arrangements in its place, keep it clean and ready for use.
y Systematic Cleaning:- Systematic cleaning and inspection of work areas and equipment help in understanding current conditions and determine if corrective action is required.
y Standardizing:- Developing common methods for consistency.
y Sustaining:- Sustaining is aimed at maintaining the improvements of 5S.
The benefits of 5S are:
y Neat and Clean Workplace:- When a work area is clean and organized, tripping hazards and other dangers are eliminated.
y Improves self-discipline:- The 5S system, especially its visual nature, makes abnormal conditions noticeable and makes ignoring standards more difficult.
y Improves culture:- It fosters better teamwork and enthusiasm
y Less wasted time:- When tools and materials are accessible and orderly, workers need less time
to access the same and no time is wasted on searching the items.
y Less space:- When unneeded items are eliminated and the needed ones are organized, required floor space is dramatically reduced.
y Improves:- Improves and increases smooth working, safety and productivity.
A clean and tidy workplace leads to greater well-being, increased motivation and enhances the company’s image. People like to work in a well-organized and clean environment. They feel better about themselves, better about their work, and they restore the self-discipline that is found in winning teams. Although 5S will not solve today’s competitive challenges, it does provide a solid foundation for achieving operational excellence. The teamwork and discipline built through 5S also improves worker-to-worker and worker-to-manager relationships.
A safety program won’t survive without accountability and ownership within the organization. In a successful safety culture, everyone is a stakeholder.

How to handle Hydrogen Sulfide
Hydrogen Sulfide or H2S is safe as long as it is properly
controlled. Once mismanaged, it is an extremely toxic gas
to which certain exposures can lead to death. One breath is
enough to kill a person. It can quickly paralyse the breathing
organs and lead to death. It is harmful to health even in small
quantities.
Low concentrations of H2S when mixed with air smells like
rotten eggs. Slightly higher concentrations when mixed with
air will kill your sense of smell. Sometimes it is called acid gas,
stink damp, swamp gas, etc. It is commonly found in the oil
& gas industry, water works, paper mills, sewers, swamps,
telephone tunnels, etc.
It is formed through biological action and/or decomposition. It
is a combination of hydrogen and sulphur atoms. The process
of combination takes place in several ways by either:
y Bacteria
y Chemical reactions
y The decomposition or decaying process of organic matter-
vegetation etc.
It can rise from the decomposition of organic animals and/or
vegetable materials with bacteria.
Chemical Properties of H2S:
Color : Colorless
Specific gravity : 1.189
Solubility in water : 0.672 gr / 100 ml
Freezing point : - 49ºC (= - 56.2 ºF)
Ignition point : 260ºC (= 500ºF)
Explosion range : 4.3 – 45% by volume in air
Classification on operating conditions:
Condition # 1: Potential danger < 10 ppm
Condition # 2: Reasonable danger, < 20 ppm to 10 ppm
Condition # 3: Extreme danger > 20 ppm
H2S Gas Detector device and monitoring procedures are being
implemented at Saudi Aramco projects and all other TL projects
of oil and gas field area.
Physical Properties of H2S:
y It is poisonous. Death occurs quickly in significant
concentrations.
y It is colorless.
y It is heavier than air. It tends to settle in low lying areas
y Readily dispersed by wind movements or air currents.
y It burns with a blue flame producing Sulfur dioxide (SO2),
which is also an extremely toxic gas.
y It is a explosive and may form explosive mixtures with air
and oxygen.
y It is soluble in water, liquid hydrocarbons and other liquids
found in drilling and oil industry.
y It is highly corrosive to certain metals.
y It has a smell of rotten eggs at a low level of concentration.
y High concentrations paralyze the olfactory nerve,
eliminating sense of smell.
A measurement of a person exposure to H2S is called Threshold
Limit Value (TLV). Acceptable TLV level to which people can be
continuously exposed without harmful effect on a 8 hour a
day work at 40 hour a week is approximately 10 ppm (parts
per million by volume in air to which not in stream condition).
Exposure on one occasion to levels of between 500 and 700
ppm can prove fatal.
Effects on exposure:
y Low concentrations exposure can cause eye, nose and
throat mucus and will eventually cause vomit.
y Medium concentrations exposure can cause anxiety, head-
ache, dizziness, vomit, nausea, cough and lack of balance.
y High concentrations exposure leads to rapid fainting and
may lead to death if the person is not immediately taken
to a non polluted area.

What does heat stress do to you?
Gulf areas particularly have very high temperatures during
the summer season. During this period, it reaches its peak
temperature of up to 50° C. Heat stress is more visible
during this season.
Heat stress is a serious occupational health hazard to
individuals because it disturbs the thermal equilibrium of
the body. The condition becomes very alarming when high
degree of heat combines with metabolic heat during heavy
physical work.
Human body always generates heat and passes it to the
environment. The harder your body is working, the more
heat it has to lose. While we work or play, our body
generates heat through muscle movements. If the outside
ambient temperature is more than our body temperature,
then our body receives heat from the surroundings. Internal
body heat increases from work or high temperature.
Surface blood vessels get bigger; pulse rate goes up while
putting strain on the heart and circulation system. More
blood is pumped close to the skin for cooling, while less
blood goes to the brain. Pushing the body beyond its limit
leads to an uncontrolled and explosive risk that may lead
to death or severe damage to central nervous system. The
normal human body temperature is 37°C or 98.6°F.
To prevent heat stress, people should:
y Monitor body and environment temp.
y Wear protective clothing.
y Have frequent rest breaks.
y Adapt to the heat and humidity by exposing oneself in
the morning.
y Adapt work schedules.
y Reduce heat exposure.
y Increase air flow.

Where should I use a ladder?
Ladder
Ladders are essentially a means of access/egress and should only be used as working platforms for very short duration task, where alternative platforms would be impracticable and where such task can be carried out safely using a ladder. Only industrial class ladders should be used which are in good condition, meaning no missing or broken rungs, etc.
The points a user shall consider before the usage of ladder are:
y Access ladders must be secured and extended sufficiently beyond working platform to allow for safe access / egress.
y Where access ladders run for more than 9m then suitable intermediate platforms must be provided.
y Ladder shall not be painted because it will cover defect.
y Unsound or defective ladder shall not be used.
y Be sure that the ladder is set on a firm level base and if possible fix or tie it at the base.
y Straight ladders longer than 3 meters in length should be secured or footed when this is not practical.
y Make sure that the ladder reaches 1 meter height above landing platform and alternative handhold is provided.
y The correct position of straight ladder is 1 feet out at the base for every 4 feet vertical height.
y Use the right length ladder for the job. Never lash two short ladders to make a longer one. The minimum extension of a ladder to the landing or working platform shall not be lower than 1 meter.
y Do not carry loads on ladders – use a hoist line.
y Do not lean out or over reach from a ladder – it is safer to move the ladder.
y Remove excessive mud, grease, etc., from footwear prior to climbing/descending a ladder.
y Always use both hands to climb/descend, and face the ladder.

An effective way of conducting investigation
FISHBONE Analysis
An effective way to conduct an accident investigation is using Fishbone Analysis. It identifies the potential factors causing it to an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify these sources of variation. Causes can be categoriesed as 6 M’s. It can reveal key relationships among various variables, and the possible causes provide additional insight into process behavior. Causes can be derived from brainstorming sessions. These groups can then be labeled as categories of the fishbone.
6 M’s Categories in FishBone Analysis:
y Manpower (People): Anyone involved with the process.
y Methods (Process): How the process is performed and the specific requirements for doing it, such as policies, procedures, rules, regulations and laws.
y Machines (Technology): Any equipment, computers, tools, etc. required to accomplish the job.
y Materials: Materials used while doing the task.
y Measurements (Inspections): Data generated that are used to evaluate the performance.
y Mother Earth (Environment): The conditions, such as location, time, temperature, and culture in which the process operates.
Possible areas to investigate as per category:
Machines
y Are inspections of equipment conducted regularly?
y Are certificates valid?
y Is daily inspection conducted before use?
y Is ‘safe to use’ tags available?
Materials
y Are people wearing PPE?
y Are specifications according to standards?
y Are lifting gears, harnesses certified and valid?
Mother Earth
y Is the weather condition suitable to work?
y Is the work location and working condition area reasonable for work?
Measurements
y Are inspections conducted?
y Is performance evaluation conducted?
y Is close out to non-conformances done on targets?
y Are there any analysis conducted to monitor performance?
Manpower
y Are workers competent to do the task?
y Is adequate training conducted?
y Are there any language barriers in the work place?
y Is anyone having physical and mental illness?
y Is anyone having criminal intent?
Methods
y Are there any approved methods on conducting the work?
y Is there any risk assessment conducted?
y Is the methods and risk controls on conducting the work explained to everybody involved in the task?
y Is there any emergency plan and drill?
y Is the use of sub-contractor approved?

Best Practice that Protect the Environment
PT&D International supports any effort which aims to protect the Environment for the good of the future generation. Best practices are implemented, such as, creating secondary containment and recycling of wooden material.
y The contained space should be strictly prohibited for storage purposes of other materials.
y The total containment area is to be constructed to safely accommodate the whole quantity of tank spilled product i.e., to contain 110% of the tank capacity.
y A low point in the containment tank is used to draw liquid from the containment area in a safe manner.
y If the potential risk for vehicular damage to the containment tank exists, the collision protection of concrete filled steel posts placed 1.5 meter from outer edge of the tank wall would be ideal.
Wood Waste Recycling
All resources from mother earth have limitation. Maximizing the usage of resources has protected our mother earth in so many ways such as giving time to the mother earth to replenish what was taken and reducing carbon emission.
PT & D International exercises sustainable practice of wood waste recycling. We all know that wooden materials arise from construction activities and waste has increased dramatically. Recycling wood is morally reasonable and being done in its maximum level. Example of it are using ply-wood wastes into usable materials like fire extinguisher box, nail storage box, steel rebar caps etc.
Some benefits of recycling wood materials are:
y Reducing cost of new purchases
y Improve the project environment, health and safety and sustainable practices.
y Reduces deforestation impact over the environment and preserves live trees.
y Decompose wooden waste materials releases methane gas which is a greenhouse gas that contributes to air pollution. In return, it creates global warming.
y It helps to preserve remaining forests and protects endangered tree species
y It also reduces the amount of landfill use and allows land for other productive uses.
Where is storage tank secondary containment being applied?
Sewage water holding tanks, diesel storage tanks and oil drum storage area are among suitable and ideal areas where it should be implemented. The aim of such practices is to place a secondary containment to contain any accidental spillage, ground water pollution, soil contamination and to improve worker’s hygiene.
The benefits of the secondary containment are that it helps in containment of liquids and prevents serious environmental incidents due to potential leaks, accidental tank breakages and ruptures. It also safeguards from potential spillages / overflow of liquid while transfer and lastly it prevents soil pollution, ground water contamination and potential risk of fire accidents.
Requirements while constructing secondary containment:
y It should be constructed using a single wall placed in a conventional dike system.
y Walls and base of the tanks are to be made of non-combustible and impermeable concrete material and with the base lining of geo-synthetic clay material.
y Dike walls are placed not less than 1.5 meters from the tank outer shell.
y Containment areas should not permit an accumulation of precipitation or liquids.

Protection from Heat Illness
The summer has started making the workers and
employees exposed to hot environment for long periods.
When the human body is unable to maintain a normal
temperature, heat-related illnesses can occur and may
result in even death. This fact sheet provides information
on measures needed to prevent heat-related illnesses
and death.
Risk Factors on Hot Work Environment
y High temperature and humidity
y Direct sun exposure
y Indoor exposure to radiant heat sources (Welding,
Gas Cutting)
y Limited air movement (no wind)
y Low fluid consumption
y Physical exertion
y Heavy personal protective clothing and equipment
y Poor physical condition or health problems
y Some medications, for example, different kinds of
blood pressure pills
y Lack of previous exposure to hot workplaces
y Previous heat-related illness
Health Problems Caused by Hot Environments
Heat Stroke is the most serious heat-related health
problem. Heat stroke occurs when the body’s temperature
regulating system fails and body temperature rises to
critical levels. Heat stroke is a medical emergency that
may rapidly result in death! Symptoms of heat stroke
include: Confusion; Loss of consciousness; Seizures;
Very high body temperature; Hot, dry skin or profuse
sweating. During medical emergency, make sure that
someone stays with the worker until help arrives. Move
the worker to a shaded, cool area and remove outer
clothing. Wet the worker with cool water and circulate
the air to speed cooling. Place cold wet clothes or ice all
over the body or soak the worker’s clothing with cold
water.
Heat Exhaustion is the next most serious heat-related
health problem. Symptoms of heat exhaustion: headache,
nausea, dizziness, weakness, irritability, thirst, heavy
sweating, elevated body temperature, and decreased
urine output. If a worker shows signs of possible heat
exhaustion, he should be taken to a First Aid room for
medical evaluation and treatment. If medical care is not
52 HELMET Jan - Mar 2013 Water & Effluent Treatment
53HELMET Jan - Mar 2013
available, call for an ambulance immediately. Make sure
that someone stays with the worker until help arrives.
Workers should be removed from the hot area and given
liquids to drink. Remove unnecessary clothing including
shoes and socks. Cool the worker with cold compresses
to the head, neck, and face or have the worker
wash his or her head, face and neck with cold water.
Encourage frequent sips of cool water. If the worker is
unable to drink, get emergency medical help immediately.
Heat Cramps are muscle pains usually caused by
physical labor in a hot work environment. Heat
cramps are caused by the loss of body salts and
fluid during sweating. If a worker shows signs
of possible heat cramps: Workers should replace
fluid loss by drinking water and having a snack,
and/or carbohydrate-electrolyte replacement
liquids (e.g., sports drinks) every 15 to 20 minutes.
Workers should avoid salt tablets. Get medical
help if the worker has heart problems, is on a low
sodium diet, or if cramps do not subside within one hour.
Heat Rash is the most common problem in hot work
environments. Heat rash is caused by sweating and looks
like a red cluster of pimples or small blisters. Heat rash
usually appears on the neck, upper chest, in the groin,
under the breasts and in elbow creases. If a worker
shows signs of possible heat rash: The best treatment
for heat rash is to provide a cooler, less humid work
environment. The rash area should be kept dry. Powder
may be applied to increase comfort. Ointments and
creams should not be used on a heat rash. Anything that
makes the skin warm or moist may make the rash worse.
Preventing Heat Illness
The best way to prevent heat illness is to make the work
environment cooler.
y Train workers and supervisors about the hazards
leading to heat stress and ways to prevent them.
y Allow workers to get used to hot environments by
gradually increasing exposure over a 5-day work
period. Begin with 50% of the normal workload
a nd time spent in the hot environment and then
gradually build up to 100% by the fifth day. New
workers and those returning from an absence of
two weeks or more should have a 5-day adjustment
period.
y Provide workers with plenty of cool water in
convenient,visible locations close to the work area.
Water should have a palatable (pleasant and odor
free)taste and water temperature should be 10-
150C if possible.
y Remind workers to frequently drink small amounts
of water before they become thirsty to maintain
good hydration. Simply telling them to drink plenty
of fluids is not sufficient. During moderate activity,in
moderately hot conditions, at least one pint of
water per hour is needed. Workers should drink
about 150 ml or a medium-sized glass-full every 15
minutes. Instruct workers that urine should be clear
or lightly colored.
y Be aware that it is harmful to drink extreme amounts
of water. Workers should generally not drink more
than a total of 48 cups of fluid in 24 hours.
y Reduce the physical demands of the job, such as
excessive lifting, climbing, or digging with heavy
objects. Use mechanical devices or assign extra
workers.
y Monitor weather reports daily and reschedule jobs
with high heat exposure to cooler times of the day.
When possible, routine maintenance and repair
projects should be scheduled for the cooler seasons
of the year.
y Schedule frequent rest periods with water breaks in
shaded or air-conditioned recovery areas.
y Workers are at an increased risk of heat stress from
personal protective equipment (PPE), especially
from wearing semi-permeable (penetrable) or
impermeable clothing (such as rubber),when
the outside temperature exceeds 250C, or while
working at high energy levels. These types of
clothing material trap the heat close to a worker’s
body. Workers should be monitored by establishing
a routine to periodically check them for signs and
symptoms of overexposure.
