3

• There are Unexpected releases of toxic, reactive, or flammable chemicals in processes involving highly hazardous chemicals.

• there is a potential for an accidental release any time they are not properly controlled, creating the possibility of disaster.

• An effective Process Safety Management program can help prevent releases and prepare for emergency response in the event of a chemical release.

4

• A process is an activity or combination of

activities including any use, storage,

manufacturing, handling or the on-site

movement of Highly Hazardous Chemicals.

• Process Safety Management is intended to

prevent an incident finally leading to a

Disaster.

Good management practice

Process steps that enable improvement

in decision making

A logical and systematic approach

Identifying opportunities

Avoiding or minimising losses

Risk Management is the logical and

systematic method to identify,

analyse, treat and monitor the risks

involved in any activity or process.

Risk Management is a methodology that helps managers make best use

of their available resources

What is Risk Management?What is Risk Management?

8

• It is the complete process of understanding risk, risk assessment, and decision making

to ensure effective risk controls are in place

and implemented. • Risk management begins with identifying possible

hazards leading to ongoing mgt of those risks

deemed to be acceptable. management of those risks deemed to be

acceptable.

Risk ManagementRisk Management

9

Risk Management analyze risk (for probability and

consequences), so the risk (with respect to acceptability) can be assessed, and ultimately managed

it is simply not possible to commence this cycle without first effectively identifying the hazards of concern.

10

Process safety is a blend of engineering and

management skills focused on preventing

catastrophic accidents, particularly explosions,

fires, toxic releases (associated with the use of

chemicals and petroleum products).

11

Process safety management refers to the

general management systems in place to

address major accident hazards

12

Process Safety Management have

a positive effect on safety of employees

offer potential benefits to employers, such

as increased productivity,

smaller businesses with limited resources

might consider alternative avenues of

decreasing risks associated with highly

hazardous chemicals at their workplaces.

13

• One method is reducing inventory. The reduction in inventory results in reducing the risk or potential for a catastrophic incident. Employers can establish more efficient inventory control by reducing, to below the established threshold, the quantities of highly hazardous chemicals onsite.

• When reduced inventory is not feasible, disperse inventory to several locations onsite so that a release in one location will not affect another location. This is also a practical way to reduce the risk or potential for catastrophic incidents.

14

• Various lines of defense that have been incorporated into the design and operation of the process to prevent or mitigate the release of hazardous chemicals need to be evaluated and strengthened to ensure their effectiveness at each level.

• Process safety management is the proactive identification, evaluation and mitigation or prevention of chemical releases that could occur as a result of failures in processes, procedures, or equipment.

15

• To control these types of hazards,

employers need to develop necessary

expertise, experience, judgment, and

initiative within their work force to properly

implement and maintain an effective

process safety management program

16

Process Safety Management (PSM) is

the application of management

principles and systems to identification,

understanding and control of process

hazards to prevent process-related

injuries and accidents.

1 ACCOUNTABILITY: OBJECTIVES & GOALS

• Management commitment at all levels is necessary for PSM to be effective.

• objectives for establishing accountability are to demonstrate the status of process safety compared to other business objectives (e.g. production and cost), to set objectives for safe process operation and to set specific process safety goals.

• These objectives should be internally consistent, i.e., supported by appropriate resources.

21

2. PROCESS KNOWLEDGE & DOCUMENTATION

Information necessary for the safe design,

operation and maintenance of any facility

should be written, reliable, current and

easily accessible by people who need to

use it.

22

3. CAPITAL PROJECT REVIEW & DESIGN PROCEDURES

Appropriation request procedures Risk assessment for investment

purposes Hazards review Siting (relative to risk management) Plot plan Process design & review procedures Project management procedures

23

4 PROCESS RISK MANAGEMENT

Hazards identification Risk assessment of existing operations Reduction of risk Residual risk management (in-plant

emergency response and mitigation) Process management during emergencies Encouraging client & supplier companies

to adopt similar risk management practices Selection of business with acceptable

risks

24

5. MANAGEMENT OF CHANGE

Clear definition of change (scope of application); Description & technical basis for the proposed change; Potential impact of proposed change on H,S & E Authorization requirements to make the change; Training requirements of change for people at work; Updating of documentation including; process safety

information, operating & maintenance procedures, alarm and interlock settings, fire protection systems, etc.; and

contingencies for "emergency" changes.

A system to manage change is critical to the operation of any facility. A written procedure should be required for all changes except replacement in kind. system should address:

25

6 PROCESS AND EQUIPMENT INTEGRITY

Pressure vessels and storage tanks; Piping, instrument and electrical systems; Process control software; Relief and vent systems and devices; Emergency and fire protection systems; Controls including monitoring devices and sensors, alarms and

interlocks; and Rotating equipment.A documented file should be maintained for each equipment.

Procedures for fabricating, inspecting and maintaining equipment vital to process safety. Written procedures should be used to maintain ongoing integrity of process equipment such as:

26

Human factors are a significant contributor to

many process accidents. Three key areas are

operator – process/equipment interface,

administrative controls and human error

assessment.

7 HUMAN FACTORS

27

8. TRAINING AND PERFORMANCEPeople to be trained in the skills & to have ongoing retraining to maintain these skills.

9 INCIDENT INVESTIGATION

• Major incidents• Near-miss reporting• Follow-up & resolution• Communication• Incident recording

• Third-party participation as needed

28

10. CO. STANDARDS, CODES & REGULATIONS

A management system is needed to

ensure that the various internal and

external published guidelines, standards

and regulations are current, disseminated

to appropriate people and departments,

and applied throughout the plant.

29

11 AUDITS AND CORRECTIVE ACTIONS

The purpose of safety audits is to determine the

status and effectiveness of safety management

efforts versus goals and also the progress toward

those goals.

30

12. ENHANCEMENT OF PROCESS SAFETY KNOWLEDGE

A management system for process safety should be

designed for continuous improvement. Safety

requirements are becoming more stringent, while

knowledge of systems and technology is growing.

Safe operation of a process plant calls for personnel

to stay abreast of current develop-ments, & for

safety information to be accessible.

32

What is a disaster?

An occurrence inflicting widespread destruction and distress

DISASTERHazardVulnerability

33

What is a disaster?

“A sudden calamitous event bringing great damage, loss or destruction.”

“What happens only if you are not prepared for it.”

“An event the timing of which is unexpected and the consequences seriously destructive.”

34

What is Disaster?

A catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or man- made causes, leading to accident, and resulting in substantial loss of life or human suffering or damage to, and destruction of property, or damage to, or degradation of environment, and is of such a nature and/or magnitude as to be beyond the coping capacity of

the community of the affected area. (Source: DM Act, 2005)

35

Factors contributing to industrial disasters

Storage of flammable, explosive, or toxic chemicals, including radioactive materials

Uncontrolled release of un-reacted chemicals, chemical reaction products, or energy from a chemical reaction

The presence of people in the proximity to result in exposure

Exposure sufficient to cause serious injury or death

36

Bhopal Disaster -3 Dec., 1984–A Turning Point

Methyl isocyanate (MIC) released resulting in over 2 500 dead and 100 000 injuredBrought home the unprecedented scale of disaster potential of a hazchem incident in terms of loss of life, health and injury and evacuation needed and created a compelling evidence to apply a holistic Disaster Management approach to chemical safety A new era of restructuring and inducting new HAZCHEM control systems & procedures started

37

Major post-Bhopal developments

Major Hazard remained an unknown concept

in India till the Bhopal disaster

38

Major post-Bhopal developments

BROADER FOCUS

The focus of protection was made more

comprehensive to include property,

environment and community instead of the

earlier narrow focus only on employees
