Document Safe Work Procedure : Step-by-Step of how to Raise the OFC Bracket Past Backstraps







1. SPECIFIC RISKS IDENTIFIED FOR THIS PROCEDURE

1.1 Specific Risks Associated with the OFC Construction Activity

1.1.1 The erector will be handling insulated tools (poles) which could make direct contact with "live" equipment.

1.1.2 The erector will be manipulating conductive brackets near "live" electrical equipment. Should such a bracket bridge out an insulator, the mast structure will become "live" and a person can be electrocuted.

1.1.3 Strong winds and rain may cause the workman to loose control of the installation tools – (work in strong winds and rain prohibited).

1.1.4 In tunnels, under bridges and in station yards the "live" equipment do not follow the usual open line structure pattern and safe working clearances may be compromised.

1.1.5 The removal of trees which foul the route near the "live" OHTE.

1.1.6 The erecting of additional OFC support poles in the rail servitude near the "live" electrification equipment (specifically the use of vehicle mounted cranes)..

1.1.7 Passing trains.

1.2 Scope and Purpose

1.2.1 This safe work procedure covers the erection of self-supporting optical fibre cable on 25 kV and 50 kV AC overhead high tension electrification (OHTE) masts for Freight Rail, a Division of Transnet Limited.

1.2.1.1 The installation methodology is to use special brackets and insulated tools (sticks) to do these installations "remotely" i.e. from formation level.

1.2.1.2 Where possible, construction will mostly take place under live traction power conditions and with the normal operation of train services.

1.2.1.3 This procedure generally covers safety precautions and safe working procedures during construction.

1.2.1.4 The Electrical Officer (Contracts) appointed for the section shall at his own discretion decide if any procedure is safe or not and inform the Transport Telecom, Project Manager or Supervisor accordingly.







1.2.2 The objective is to install the major component of the cable above ground. Underground sections should be kept to a minimum. Underground trenches, Rail Pipe Crossings and Pipe and Chamber systems may be required or utilised where these exist.

1.2.3 To avoid additional splices the same optical fibre cable must be utilised for aerial and buried sections. The OFC will be of the all-dielectric aerial self-support type. On AC sections OFC with anti-tracking sheath shall be used.

1.2.4 This document focuses on safety and safe work procedures and must be read in conjunction with Specification SPC-00575 for the Engineering Requirements for the Installation of Optical Fibres on overhead track structures. Please note that although some sections and clauses are similar, this document does not replace above specification. For any safety related requirement, this document takes preference.

1.2.5 This procedure also sets the minimum standards for materials, tools and techniques to be used in aerial optical fibre cable installations, and may not be deviated from without the permission of the Transport Telecom, Project Manager and Electrical Officer (Contracts).

1.2.6 Where reference is made to approved materials, tools or techniques, this approval must be obtained from Transport Telecom, Project Manager, who will co-ordinate any necessary interfacing with the Electrical Officer (Contracts) and relevant authorities.

1.3 The following Annexures Form Part of these Instructions and Procedure

1.3.1 E7/1 : Specification for works on, over, under or adjacent to railway lines and near high voltage equipment.

1.3.2 E.4E : Safety arrangements and procedural compliance with the occupational health and safety Act; Act 85 of 1983 and regulations.

1.3.3 Annexure 1 : Safe working procedure, photographs and methodology (with DVD) on Safety Shield and tools (Installation procedure to remotely install cable support to traction masts in AC electrified sections).

1.3.4 DVD on Electrical Safety Awareness.

1.3.5 Daily Safety Work Instruction for the Installation of Optical Fibre Cable on OHTE (INS-00007).

1.3.6 Electrical Shock Incident Awareness.

1.3.7 Contractors Induction to Safe Working Procedures.







1.3.8 Installation Guidelines for the safe positioning of OFC on OHTE structures from Senior Manager Electrical (Infra Maintenance) (S.PL&T) 1 CAO/13/3/1/6 of 9 November 2001.

2. GENERAL SAFETY PRECAUTIONS

2.1 Due to the proximity of live conductors the installer must ensure that his employees installing the cable on the masts obtain a Category C certificate from the relevant authorities before any work can be carried out on the masts.

2.2 The Contractor's employees must be trained for competence and understanding of the basic electrical safety requirements. The certificate obtained will not be transferable. The cost of the training will be borne by the Installer or Freight Rail as stipulated in the contract document.

2.2.1 The supervisor of the team must have a Letter of Training in his possession on site. This letter of training involves successful completion of the INFR and COM modules presented at accredited Training Schools. INFR involves supervision of staff in the permanent way environment and COM involves signing of work permits, which is required when installing fly-over crossings. On successful completion of the person will hold a yellow SPOORNET 436 card.

2.2.2 All workers who will handle the OFC or associated brackets on the electrification structures must hold a valid Category C certificate. This requires (a) successful attendance of a 5-day course held at an accredited

Training School, and (b) certification by an examining officer appointed for each

infrastructure depot. In completion the person will have a G-Green certificate, which must be carried on his person.

2.2.3 An Electrical Officer (Contracts), being an official from the Infrastructure Depot, must be appointed for every contract. The Contract's Project Manager must advise the contractor who this person is and arrange initial consultation between the parties.

2.2.4 Whenever OFC cables must cross over the Electrification, a work permit must be arranged. The electrical Officer (Contracts) must be consulted to ensure that timeous arrangements are made. This notice period can be 3 weeks or longer.

2.2.5 Flagmen must be deployed in terms of the General Appendix Chapter 11.

2.3 The installer and his employees installing the cable must be fully conversant with the Electrical Safety Instructions, Transnet specifications E.7/1 and E.4E and other safety documentation and instructions referred to in this document.







2.4 A person authorized with a Category C certificate must maintain the prescribed clearance for the electrification voltage applicable.

2.5 The brackets to be fitted to OHTE masts by means of remote tools (sticks) must always be "under control" by the workmen using the tools to prevent accidental "flash-over" (possible bridging-out of insulators).

2.5.1 Where the face of the mast is open (not obstructed) the bracket must be opened marginally to allow easy sliding up the mast, without the risk of the bracket dislodging from the mast.

2.5.2 Where the mast is fitted with one or two backstraps and the OFC bracket must be lifted past these backstraps, a safety shield with ring (as per the safe working procedure) must be used to keep the tools "under control".

2.6 In all instances where the safety of workmen is jeopardised, electrical permits and/or track occupations must be requested. The Electrical Officer (Contracts) will decide where occupations are required. Notification could be required up to four (4) weeks in advance.

2.7 Under bridges where live cross span wires are involved and at make off masts and where the live conductors approach the optical fibre cable very closely, a standard warning board must be fitted. Electrical personnel must be approached to arrange for a work permit to fit the cable and warning boards.

2.8 No attempt must be made to install the cable in windy conditions, especially when the sag (before tensioning) is blown in the direction of the track. Supervisors must use their discretion in this regard.

2.9 No metal ladders will be allowed for construction but only wooden or fibreglass ladders.

2.10 Remote AC bracket installation tool (sticks) must be kept clean may not be used in wet or rainy conditions. This tool must be tested for 50 kV isolation and approved by Freight Rail, Technology Management Department and carry a marking to that effect.

2.11 Hard hats, protective clothing and safety boots must be worn during construction.

2.12 Optical fibres are extremely thin and can easily penetrate skin and eyes. Any off cuts or bare pieces of fibre must be properly disposed of in sealed containers. Optical fibres are categorised as hazardous materials and require special disposal measures.







2.13 Care must be taken whilst testing as the laser in test equipment produces an invisible light, which can cause permanent eye damage. All fibres should be treated as "lit".

2.14 All personnel involved in the installation and testing must be made aware of the above safety aspects by attending the "Induction Training" and viewing the relevant Freight Rail Safety DVDs and any other materials that the Project Manager deems necessary.

2.15 A Safety Plan as required by Freight Rail must be submitted before any work may commence. Details of the Safety plan may be obtained from the Project Manager.

2.16 A Site Safety File as required by Freight Rail must be available on site and kept current. Details and content of the Site Safety File may be obtained from the Project Manager.

2.17 The Installer must comply with the "Installation Work Procedures for the Installation of Optical Fibre Cable" (latest version).

3. INSTALLATION (Methodology)

3.1 This portion is included to allow the Project Supervisor and Electrical Officer (Contracts) to identify safety and risk situations before work commences and recommends specific requirements.

3.2 Preparation must be carried out on the route on which the cable is to be erected. Trees, bushes and grass must be cut so that work can be carried out without any obstacles. The aerial route must be at least three (3) metres clear of bush and trees within the reserve. Where excessive trees or bush, which could become a fire hazard, are encountered, an alternative route must be chosen. Tree branches overhanging the cable must be removed.

3.3 Erection of OFC on AC Traction Masts

3.3.1 Fit the universal multipurpose bracket at ±1,5 metres above ground level.

3.3.2 Fit a pulley/sling on every suspension bracket (at a working height) for a distance equivalent to the length of the cable to be hauled in.

3.3.3 Place the OFC drum with cable away from the mast where the cable will pass through the first pulley/sling. This would prevent the cable from bending too much whilst being hauled. Under no circumstances should the cable be bent excessively. The OFC drum should be placed on cable jacks with an axle. The rate of the hauling should be controlled from this point.







3.3.4 The cable must be fed off the drum according to the speed with which the cable is hauled. Care must be taken that the cable is not tightening between the drum and the first pulley. A constant tension must be maintained on the cable by braking of the cable drum when necessary. Tension must be maintained to ensure minimum OFC contact with the ground.

3.3.5 OFC hauling should be avoided on very windy days, especially if the wind blows the cable in the direction of the track.

3.3.6 The hauling team must haul the cable evenly and slowly to prevent the cable from jerking which can result injuring workers or in broken fibres.

3.3.7 Good communication between persons at the drum, alongside the cable-end and the hauling team, is absolutely essential and must be available at all times. If communication breaks down, the hauling must be stopped immediately until such time that the communication had been re-established.

3.3.8 When hauling the cable, a person, in full communication with the team, must walk alongside the cable-end to ensure that the cable is taking the designated route. The OFC must not twist, especially at angle-masts where the possibility of twisting is great. When the cable starts twisting, hauling must be stopped immediately. The cause of the problem must then be pinpointed and rectified.

3.3.9 The cable sag and tension under normal installation conditions may vary around bends. Special care must be taken when the cable is removed from the pulley or sling and placed onto the termination fitting so that the cable does not exceed the prescribed tension.

3.3.10 A termination bracket and fitting (dead end) must be installed at the beginning of each length. Where only false terminations occur in a cable section the cable must be tensioned sequentially for every false termination section.

3.3.11 The cable shall be tensioned by means of an approved device at the far end and the tension shall be continually monitored not to exceed the parameters provided by the cable manufacturer.

3.3.12 On sections with a number of angle masts, it may be required to tension the cable over shorter distances. In this case care should be taken not to damage the cable at the intermediate tensioning points.







3.3.13 Sufficient time shall be allowed for the tensioned cable to settle. This time is when there is no longer a movement on the tensioning scale. When the correct tension has been achieved, the suspension (PLP) and termination (PLP) fittings shall be fitted.

3.3.14 The cable must be marked at all anchor points in an approved manner to indicate possible slippage.

3.3.15 The site supervisor must record the final stringing tensions and terminated span lengths on a control sheet. The site supervisor must submit these sheets with the site diaries for scrutiny and retention.

3.3.16 Once tensioning and splicing of the cable is completed, the suspension brackets shall be moved sequentially and incrementally up the masts in at least three steps with various lengths of installation tools to the correct final position on the mast. Note that although approved non-conductive tools will be used, the installation teams shall avoid touching any high voltage carrying infrastructure at all times.

3.3.17 The splicing team must strive to keep-up with the hauling team. If this is not the case, additional labour will be is required to lower and raise the cable especially for splicing purposes.

3.4 Cable Slack

3.4.1 At positions where it may be required to accumulate cable slack due to the nature of the route, this slack must always be coiled in a figure of eight to avoid twisting of the cable. In muddy or dusty conditions the figure of eight must be done on a ground sheet to avoid soiling of the cable.

3.4.2 After the hauling process, sufficient slack must be left for splicing purposes. Less cable slack is required for AC-type joint splicing as the joint closure is moved up with the cable, but sufficient slack must however be left for splicing purposes.

3.4.3 Ten (10) metres OFC on the hauling end, must be cut off by the installation team. The installer must ensure that this length is cut off during the installation process.

3.4.4 The slack shall be coiled in two separate coils of minimum 500 mm diameter, tied with UV stabilised coated stainless steel cable ties at four positions and secured on the PLP dead-end. See drawing TC 000172 for details.

3.4.5 A small amount of slack only, between 250 mm and 300 mm (sag), must be allowed at false terminations.







3.5 In order to avoid sharp angles in the vertical plane when going over or under bridges a gradual increase or decrease of the route shall be obtained by adjusting the suspension brackets upwards or downwards on the masts, but only as directed by the Electrical Officer (Contracts).

3.6 Intermediate Poles

3.6.1 Intermediate telephone poles (where required) must be installed where span lengths exceed 70 metres or where the cable veers away from the track for any reason. Intermediate poles must be of the wooden, steel or concrete telephone type. The ground clearance of the suspended cable must not be less than 7,0 metres.

3.6.2 Where the intermediate wooden pole is in the danger of burning, a 2 metre high-galvanised metal sleeve must be fitted around the base of the pole. In high theft areas, concrete poles may be required.

3.6.3 The Project Manager must obtain approval from the Electrical Officer (Contracts) for the erection of intermediate wooden, steel or concrete poles in the vicinity of electrified tracks. If the pole is planted closer to the OHTE than its length (in the case of the pole falling over), permits (dead orders) must be arranged in conjunction with the Electrical Officer (Contracts).

3.6.4 To make the poles more visible at night, a reflective band of UV resistant material must be fixed to the pole next to service or other roads at 1,5 metres above ground level. Pole stays must also be fitted with reflective boards.

3.7 Underground Installation

3.7.1 At all instances where it becomes necessary to install the cable underground the cable must be protected as follows :

3.7.1.1 High-density polyethylene conduit of minimum 40 mm diameter.

3.7.1.2 Approved concrete slabs placed longitudinally over the cable and duct if a depth of 800 mm cannot be achieved.

3.7.1.3 A combination of the methods above, depending on the class of protection required.

3.7.2 To protect workmen and other parties, open trenches must be barricaded if left open overnight or for a considerable time. In general pedestrian areas, illumination shall be used after dark as stipulated in specification No. SPC-00029.







3.7.3 Warning tape with a distinctive marking, i.e. "optic fibre cable" must be installed above the cable and 300 mm below ground level.

3.7.4 Track crossings must be in accordance with specification E7/1 and Specification SPC-00029. On specific lines, Transnet could insist on doing the track crossings themselves.

3.7.5 Cable markers must be provided and planted wherever the cable is laid in the ground. Cable markers must be planted as stipulated in specification No. SPC-00029. The fibre optic marker shall have a distinctive mark, i.e. OFC, and must be painted yellow.

4. GENERAL

4.1 These safety rules must be conveyed every morning in a very simple manner to all workmen.

4.2 A translator must be used to translate and explain the rules to co-workers.

4.3 In the case of new workers or workers that have no previous experience of work next to railway lines or on electrification traction masts, assurance should be obtained that these workers have a proper understanding of these safety rules.

5. REGULATIONS WITH REGARD TO SAFETY CLOTHING

5.1 All workers must wear safety boots when working with heavy materials. Safety boots can prevent an injury if a heavy object drops on a worker's foot.

5.2 Reflective safety vests must be worn at all times to assist train divers and flagmen with visibility and assist to warn workers timeously. Nametags and Employer Name must be attached to safety vest.

5.3 Safety helmets must be worn when workers are exposed to falling objects and on all "Construction" sites.

6. FLAGMEN

6.1 Flagmen must blow a whistle or hooter when a train approaches.

6.2 Workers must ascertain themselves on which track and from which direction the train approaches, before standing clear.







6.3 Emphasis must be placed that MOST ACCIDENTS occur when workers stand clear from one train and accidentally move in front of another passing train.

7. RULES THAT ARE APPLICABLE WHEN WORK IS DONE NEXT TO THE RAILWAY LINE

7.1 The second MOST injuries occur when passing trains hit tools and equipment used by workmen. Tools like picks, shovels and materials like cable, clamps and cable sticks must never be placed on or near railway lines.

7.2 All work must stop when a train passes the work site. Workers, tools and materials must be kept at a safe distance.

7.3 A suitable certified person must determine if it is safe to work on a ladder. If it is not safe, the certified worker must carry out the work.

7.4 Only fibreglass ladders will be allowed.

7.5 Workers must not cross the tracks unnecessarily, but remain on the side where the work is being carried out. Works may NOT sit or rest on the railway line.

8. SAFETY ASPECTS

8.1 It must be explained to all workers how dangerous the overhead lines are. If any metal object should touch the wire, the metal will conduct electricity and cause serous injury or death.

8.2 Thus NO metal ladders are allowed.

8.3 When carrying metal materials like "ducting" or metal pipes, it must be carried horizontally by at least two (2) workers.

8.4 It must be emphasised that non-metallic objects like wooden poles will conduct electricity in wet weather conditions.

8.5 No person will be allowed to work on an electrification mast without a valid C-Category certificate.

8.6 Any person using push-up sticks must be in possession of a valid C-Category certificate.

8.7 Under NO circumstances must work be carried out on electrical traction masts when they are or wet and damp.

8.8 For the fitting of push-up brackets, push-up sticks must be constructed of Transnet approved materials (pantograph sticks).

8.9 The push-up sticks must be clean and dry or else it may conduct electricity. Regardless, contact with the overhead traction conductors must be avoided at ALL

times.







9. ELECTRICAL SHOCK

9.1 Remember all overhead wires are dangerous. All wires must be treated as live!

9.2 Breakdowns of electric wires must be treated as "live and dangerous" STAY CLEAR!!!!

9.3 Treatment of electrical shock when person still in contact with live equipment :

� Keep hand off + call the doctor

� Advise electrical control : 1. Have power switched off.

2. Section to be earthed.

3. Work permit to be issued

� Apply fist aid when safe.

9.4 The voltage of overhead and underground power lines must always be considered dangerous, even with the line "earthed".

9.5 Ladders must always be used in such a manner that the distance from the base of ladder to any "live" equipment is greater than the fully extended length of ladder, plus three (3) metres.

9.6 Ladders must be secured to the mast at the top with safety strap. Ladder carriers / General Workers must hold ladders in position to prevent slipping.

9.7 When working within signal gantry make sure that you take up a safe potion to ensure that no portion of your body, tools or equipment hang or project beyond or below the restricted barriers provided.

9.8 Do not leave the gantry access way.

11. WORK NOT PERMITTED WHILE ELECTRICAL EQUIPMENT IS "LIVE"

11.1 All electrical equipment and all electric wires may be "live" and dangerous and must not be touched. Even loose or broken wires lying on the ground may still be "live" and must be avoided.

11.2 No person may climb any pole or structure which supports exposed "live" overhead wires or electrical equipment.

11.3 No person may climb, ride or work on the roof of, or on the top of any load or equipment carried on any rail or road vehicle or any machine under exposed "live" overhead wires.

12. WORK ON THE OUTSIDE OF ROLLING STOCK (INCLUDING LOADING OR UNLOADING)

12.1 No person may stand, climb or work whilst on any platform, surface or foothold higher than the normal unrestricted access way, namely –

12.1.1 the floor level of wagons,

12.1.2 external walkways on diesel, steam and electric locomotives, steam heat vans, etc. and







12.1.3 walkways between passenger coaches and locomotives.

12.2 When in the above positions –

12.2.1 no person may raise his hands or any equipment he is handling above his head,

12.2.2 the handling of long lengths of material such as metal pipes, etc. should be avoided, and only if essential must be handled as close as possible to the horizontal position below head height,

12.2.3 responsible persons must always warn all persons under their control against the dangers involved with exposed "live" wires,

12.2.4 no person may whilst on electric rolling stock approach or work on any part of the pantograph, hooter or other roof equipment, except the headlight, and

12.2.5 train personnel may give the recognised hand signals from the floor and steps of wagons and recognised positions on locomotives not higher than footplate level.

13. WORK PERMITS

NOTE : A work permit is a written application and an authority to proceed with work on high-voltage electrical equipment after it has been isolated and earthed. It is an assurance that the equipment has been made "dead" and that it will not again be made "live" until the permit has been cancelled.

13.1 Work on high-voltage electrical equipment which has been isolated and earthed may only be undertaken under cover of a work permit, unless otherwise provided in these instructions.

13.2 Work boundaries within which work may be carried out must be pointed out to personnel in the most suitable manner. The method used must take into account the competence of the personnel concerned.

NOTE : A work permit will provide safety to personnel only if the work boundaries within which work may be carried out are completely clear to all persons concerned and are constantly observed by them.

13.3 The work boundaries can be pointed out by using a physical means of identification, e.g. the earth connections where they can be placed in conspicuous positions, warning notices, flags or conspicuously coloured tapes suitably attached to the overhead equipment. In cases of particular danger the work boundaries concerned must be effectively marked at suitable intervals, e.g. in a yard where a "live" line may overlap a work permit area.







14. WORK TO CLEARANCE FROM

14.1 An authorised person, category A or C, or a person issued with a letter of authority may undertake work to clearance from exposed "live" high-voltage electrical equipment under the following conditions :

14.1.1 The authorised person must select a safe working position on or close to the de-energised equipment or structures where he is required to work.

14.1.2 The person must choose a safe route to and from this working position.

14.1.3 While in the safe working position and moving to and from it, the person must ensure that with outstretched arms, no part of his body or the tools or equipment he is handling, come within the safe clearances to adjacent exposed "live" high-voltage electrical equipment laid down in the following table :

SAFE CLEARANCE (ANNEXURE 6.1) TRACTION SYSTEM

CATEGORY A CATEGORY C

3 kV DC 600 mm 900 mm

25 kV AC 900 mm 1,2 m

50 kV AC 1,4 m 1,7 m

NOTE : The clearances given in this table are the minimum safe working distances. The greatest care must always be taken when working near exposed "live" equipment, and whenever possible greater clearances should be observed. Where working barriers can be used this should be done in preference to working at the clearances permitted.

14.1.4 Where safe working clearances cannot be observed from the exposed "live" equipment, approved portable working barriers must be employed by all persons in all cases, or work must be done with the equipment "dead" under cover of a work permit.

15. IN GENERAL

15.1 Place ladders in a safe position and keep them steady.

15.2 When you see that someone is working unsafely ensure that you go through the STOP process.

15.3 We must create a culture where we look after each other.

5. RISK MANAGEMENT

Hazardous Chemical Substances Regulation 5 requires the employer to

conduct the assessment with regards to the potential exposure to Hazardous

Chemical Substances, in which the health and safety risks to which employees

may be exposed while they are at work, and record the hazards identified and

significant risk assessed. As far as reasonably practicable attempts will be

made to first of all to eliminate the risk, thereafter to control the risk, then to

minimise the risk and thereafter, insofar as the risk remains, to provide personal

protective equipment and to implement a programme to monitor the risk.

A risk assessment will be carried out to assist in deciding on appropriate action

and formulating a management plan.

The risk assessment will be carried out in two parts: the first is a material

assessment which assesses the condition of the material and the likelihood of it

releasing fibres if disturbed; the second part is a priority assessment which

takes into account maintenance activities, likelihood of disturbance, human

exposure potential, occupant activity or visitors.

All possible relevant information such as incident statistics, research reports,

manufacturer’s specifications, approvals, design criteria and performance figure

for all relevant equipment will be obtained and considered for risk assessment.

Before an assessment can be made, the relevant health and safety

representative or relevant health and safety committee will be consulted and

thereafter inform them in writing of the arrangements made for the assessment,

give them reasonable time to comment thereon and ensure that the results of

the assessment are made available to them for comment.

6. PROCEDURE

This procedure applies to all TFR employees and any worker under the technical

supervision of a TFR employee. Permit authorisation is required before any

person enters a confined space. A confined space is defined as “any place,

including any chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or other

similar space in which, by virtue of its enclosed nature, there arises a reasonably

foreseeable specified risk.

Sub-contractors may elect in their Safety Plan to comply with these procedures; in

which case, this policy is applicable. If the sub-contractor chooses to use their

own Health and Safety Plan for confined space procedures, it must be reviewed

and approved by Safety Manager, before work may commence. The safety plan

must contain procedures, which meet OHS Act requirements for entering permit-

required confined spaces, and include the completion of a permit form.

6.1 CLASSIFICATION

6.1.1 Confined space requiring permit to work with high or susceptible

risks

Confined Spaces that requires permit to work are confined spaces where actual

hazards have been identified, or where the probability of a hazard is significant.

Evaluation using the Confined Space Entry Permit (Appendix A) is required.

Both the confined space trained on-site supervisor and a TFR Occupational

hygienist/Technologist must sign the permit. In cases where radiological

hazards are present, a Radiation Protection Officer/specialist’s signature is

required for approval before any work can commence and where there are

electrical cables, an Electrical Supervisor’s signature is required for approval.

6.1.2 Confined space requiring permit to work with low risks

For confined spaces where a permit is required, but hazards have been

evaluated as low risk, the confined space trained on-site supervisor may

approve a procedural confined space permit and the following conditions must

be met:



REVISION: 00-01


PAGE: 9 OF 16


DOCUMENTS

• The TFR employees or contract employees who have completed Confined

Space Entry Hazards Training program will conduct the work.

• The entry permit must be completed and signed by a confined space trained

on-site supervisor and TFR Occupational hygienist/Technologist.

• All conditions for a permit-required confined space are met.

6.1.3 Non-permit required confined spaces

Confined spaces that do not contain hazards, nor have a potential to contain

hazards, do not require an approved Confined Space Entry Permit. However, a

permit must be completed by the confined space trained on-site supervisor,

and, if hazards are found not to exist, clearly marked as a “Non-permit Space”

and posted at the work site. “Non-permit Space” must be approved by the TFR

Occupational hygienist/Technologist.

6.5 Confined-space entry work permit system

A Confined Space Entry Work Permit (see Appendix A) must be completed for

all confined-spaces before entry. This permit documents in writing the

location(s) and type of work to be done, certifies that all existing hazards have

been evaluated by the responsible qualified person(s), and ensures that

necessary control measures have been taken to protect the health and safety

of the employees. Non-permit confined spaces must be identified as such by

documenting that chemical and physical hazards (e.g., oxygen levels, etc.) do

not exist and by writing “Non-Permit Space” in bold print across the work permit.

Permits will expire when the entrance is closed or at the end of the 8-hour work

shift, whichever is sooner.

6.3 Confined-space team

All person(s) entering the space (entrant) should be listed and the designated

standby (attendant) person(s). If applicable, the rotation by the designated

attendant(s) with personnel working in the confined space must be specified.

6.4 Requirements completed prior to entry

a) Detailed health and safety risk assessment should be conducted prior



REVISION: 00-01


PAGE: 10 OF 16


DOCUMENTS

to commencement of work.

b) If high electrical lines are present in the confined space, the Electrical

Supervisor (or designee) must approve the entry permit.

c) Lockout and tagout/blockout must be done in accordance with TFR

lockout and tagout procedures.

d) Lines, pipes, etc., must be blanked/capped to the extent feasible

before the confined space is entered.

e) If mechanical ventilation is required, site-specific details, such as the

direction of airflow and the placement of the air intake, must be

documented in the “Additional Information” section. The air supply

must be from a clean source: exhaust from vehicles, cranes, earth

compactors, and other potential sources of contaminants must be

considered when locating the blower.

f) The confined space must be emptied and purged of all hazardous

materials to the extent possible prior to entry. A fresh air blower

ventilation system shall be set up and in operation before and during

all inspection and maintenance procedures. If hazardous materials

have been identified or will be used in the confined space, an

Occupational hygienist/Technologist must be present to determine

their concentrations and approve the permit. If these materials

exceed, or have the possibility to exceed the Occupational Exposure

Limits, rescue equipments (e.g., hoist, lifelines, and harness) are

required, and the standby must be CPR trained.

g) Continuous air monitoring will be required for confined space that

cannot be isolated from potential contaminants. For example, flowing

sewers often cannot be blanked off, and continuous air monitoring is

required.

h) When entrance covers are removed, temporary barriers that will

protect the entrants from external hazards, such as vehicles, and

protect pedestrians from falling into the opening must guard

openings.

i) A fire extinguisher must be present if “hot work” is being performed.



REVISION: 00-01


PAGE: 11 OF 16


DOCUMENTS

j) If ionizing radiation may be present, radiation levels must be

monitored by radiation protection officer/specialist.

k) Required personal protective equipment should be specified before

entering into the confined space as also determined during the risk

assessment. If respiratory protection is required, site-specific details,

such as the type of respirator and cartridges, must be specified.

l) At least one standby person must be present at all times while the

high-risk confined space is occupied. The primary responsibility of the

standby personnel is the health and safety of the occupants in the

confined space. Standby personnel must be in constant visual/radio

contact with the occupants and must immediately notify the TFR Fire

Department and Occupational Health department if there are any

problems. The standby person should always summon emergency

rescue workers, and may never enter a confined space to attempt a

rescue. However, the standby can initiate a non-entry rescue, such

as by operating a hoist or lift.

m) If “hot work” will be performed, a Fire Safety Permit, available from

the Fire Department, must be completed and posted at the entrance

to the space prior to the start of work. All confined spaces become

permit-required confined spaces when hot work is performed in them.

In addition, welding gas cylinders may never be brought into a

confined space.

n) Personnel entering the space must receive confined-space training

prior to entering a permit-required or procedural confined space.

o) Additional lighting equipment may be needed to enable employees to

see well enough to work safely and to exit the space quickly in an

emergency, in these instances, explosion-proof lighting will be

required.

p) The explosion-proof gas monitor must be calibrated monthly and

function checked prior to each daily use. Monitoring the air inside a

confined space should be conducted prior to entering and be

conducted by a competent person. Testing a confined space for



REVISION: 00-01


PAGE: 12 OF 16


DOCUMENTS

atmospheric hazards should be done remotely before entering, and

should be done in this order: (1) ensure that proper oxygen levels are

present, (2) ensure that combustible gases are not present, (3)

ensure that toxic gases are below the Occupational exposure limit.

Common toxic gases in a confined space could be Hydrogen Sulfide

(H2S) and Carbon Monoxide (CO), but other toxic compounds could

be present.

q) Minimum health and safety equipment required before confined

space entry:

� approved gas detector (properly calibrated and that is in operation

the entire time the employee is in the confined space. This is

necessary due to the possibility of a rapid change in the confined

space atmosphere);

� fresh air blower;

� safety harness, rope, and tripod safety system (A safety harness

and lifeline which is attached to the tripod safety retrieval system);

� an approved hard hat; and

� emergency Action Plan

6.5 Confined-space monitoring procedure

In a confined space it is important to take samples at the top, middle and

bottom to locate varying concentrations of gases and vapours. There are

some gases lighter than air (i.e. methane and other combustible gases)

that can be found at the top of a confined space. There are other gases

that are heavier than air (i.e. hydrogen sulfide) that can settle near the

bottom of a confined space, and still other gases that are the same

weight as air (i.e. carbon monoxide) that can be found throughout a

confined space.

Take air samples at several levels within the confined space and

continuously monitor the space due to the fact that conditions can

change. The confined space must be tested at three levels for each

atmospheric condition. Each level must be tested for a minimum of 60



REVISION: 00-01


PAGE: 13 OF 16


DOCUMENTS

seconds. The gas detector itself can be lowered into the confined space

atmosphere with a safety line

As the remote air monitoring is completed and the area is safe for entry,

confined space entry permits should be completed and followed. After

the initial entry, monitoring the air in the confined space should be

continuous. A confined space entry attendant or standby should carry

out the continuous monitoring. Conditions in a confined space can

change without warning, due to leakage, toxic vapor release, or

disturbing the contents of the space.

Testing must include: -

• Oxygen content must be at least 19.5% in the confined space,

measured at all levels (bottom, middle, and top). The safe oxygen

level is between 19.5% and 21%. Confined space should not be

entered if the oxygen level is below 19.5% or above 21%. Due to the

extreme danger of suffocation in confined spaces, constant and

continuous oxygen monitoring is required throughout each work

period. Oxygen content above 23% can cause explosions or vigorous

burning of flammable materials, including hair or clothing.

• In circumstances where risk assessment has identified a significant

possibility for the presence of fuels, combustion products, methane

and/or biological action (e.g. oxyacetylene cutting, decontamination of

fuel tanks, sewage systems etc.) the following tests should also be

carried out: -

� Explosive/flammable vapours – limit < 2% LEL (measure

flammability at all levels of the confined space (bottom, middle,

and top). Flammability is measured in terms of the Lower

Explosive Limit (LEL). This is the smallest concentration of a

combustible gas in air that will explode when it contacts a spark or

open flame)

� Hydrogen Sulphide – limit 10ppm (8hour TWA)

� Carbon dioxide – limit 30ppm (8 hour TWA)

Procedure to be followed:



REVISION: 00-01


PAGE: 14 OF 16


DOCUMENTS

� Record hazard identification of area and/or confined space to be

entered. Reference to additional Permits to Work must be recorded.

� Identify reason for confined space entry

� Confirmation that all necessary isolation and pre-entry activities have

been carried out. Authorised persons are restricted to those who have

received information, instruction and training in this and related Permit

to Work procedures.

� The atmosphere within the confined space must be tested and

confirmed as safe before entry is permitted. Normal practice will be to

test for oxygen content however it may be necessary to test for

flammable/explosive vapours and H2S, with additional parameters

tested if identified as potentially present during the risk assessment

process. Personnel authorised to carry out gas testing are any

competent person deemed competent by the Safety Manager or

Occupational Hygienist.

� A standby man must be present at all times when personnel are in the

confined space, with additional precautions specified to meet

identified risks, e.g. RPE, harness/lift gear, flame proof lighting etc.

First aid, resuscitation and emergency communication equipment

should be made available for circumstances where access to medical

treatment may be restricted and/or a need for such equipment is

identified during the risk assessment process. All equipment must be

checked and verified as fit for use before entry of the confined space

takes place.

� No person shall enter a confined space to retrieve someone who is

unconscious without having required personnel above ground to

assist. The person entering the confined space for rescue purposes

must be equipped with the required rescue equipment and follow the

specific rescue procedure.

� Confined space authorised person to confirm pre-entry checks have

been completed satisfactorily. If breathing apparatus is required

specify type.

DOCUMENTS

� The person carrying out the work or the supervisor to confirm

acceptance of conditions imposed by the permit.

� All personnel entering the confined space must confirm acceptance of

the conditions imposed by the permit.

� The permit must be returned at the end of the day or on completion of

the work. Should it be necessary to carry on work the following day a

new work permit should be issued. The person carrying out the work

or the supervisor must sign the permit to indicate that all equipment

has been withdrawn or made safe.

� The authorised person must cancel the permit by signing it off.

1. PURPOSE

The purpose of this document is to:

• Sets forth the requirements necessary for working in confined spaces at

TFR to prevent exposure of personnel to dangerous air contamination,

oxygen deficiency, and physical hazards associated with confined

spaces. Confined spaces include, but are not limited to, tanks, ducts,

pipelines, sumps, sewers, trenches, vaults, and similar spaces not

intended for continuous human occupancy and meeting the criteria

described in General Safety Regulations, regulation 5.

• Ensuring the proper authorization of designated work.

• Making clear the exact identity, nature and extent of the work activity and

the hazards involved, including limitations on the extent of the work and

the times during which the work can be carried out.

• Specifying the precautions to be taken, including safe isolation from

potential risks such as exposure to hazardous substances, moving

equipment and electricity.

• Ensuring the individual in charge of operations is fully aware of work

activities taking place.

• Providing a system of continuous control and a record of showing the

nature of the work and that necessary precautionary checks have been

satisfactorily completed.

• Providing necessary information on related/interactive work activities and

satisfactory completion and handover of authorized work.
