Code 12 Training

• Employer shall provide training to all employees working in confined spaces before they are assigned duties under this ICOP

• Retraining shall be provided every two (2) years for AE, SP, AGT, ES or when there are changes in assigned duties and / or confined space hazards

• Employer shall a keep record of the training

16

PERMIT TO WORK SYSTEM

• To prepare permit to work based on risks identified

• Entry supervisor may issue the permit after ensuring that:

– All hazards have been identified and controlled; gas testing has been done, isolations have been carried out, and LOTO if applicable

• The permit to be closed by the entry supervisor or authorized person after the completion of the work

18

PERMIT TO WORK SYSTEM

PREPARATION FOR ENTRY

• Step 1: Request for Work by WL/PA

• Step 2(a): Isolation of Work Area

19

Step 2(b): Isolation of Confined Space

20

PREPARATION FOR ENTRY

Step 3(a): Initial Cleaning & Draining

Potentially dangerous materials which may be trapped in sludge, scale or other deposits, may be released when disturbed or heat is applied

Confined space should be allowed to return to acceptable thermal environment prior to entry.

Step 3(b): PURGING

• After the cleaning, the confined space shall be cleared of contaminants using suitable purging agents

• When flammable contaminants are to be purged, precautions shall be taken to eliminate sources of ignition, including static electricity discharges.

21

PREPARATION FOR ENTRY

Step 4: Initial Ventilation

• Ventilate all confined areas completely with normal air,

using recommended procedures even if no hazards were

detected during testing.

• Choose the best method for ventilation e.g. mechanical

ventilation, push-pull ventilation

22

PREPARATION FOR ENTRY

Step 5: Evaluation of the confined space conditions shall be conducted as follows:-

23

PREPARATION FOR ENTRY

Oxygen (OX) (<19.5% or >23.5%)

Explosive (EX) (above 10% LEL)

Toxic (TOX) (above PEL)

Step 6: Continuous Ventilation

Step 7(a): PPE for Confined Space Work

Step 7(b): Equipment to be prepared

24

PREPARATION FOR ENTRY

Step 8: Issuance of Permit to Work

25

PREPARATION FOR ENTRY

Step 9 : Entry and Work

26

PREPARATION FOR ENTRY

• What to do in case of emergency : – Stand-by person to call for help immediately using walkie

talkie or phone asking for help from ERT or BOMBA, and for medical aid

– Wait for help. Do not enter the confined space, do not leave the area.

– Start ventilation equipment (if not already on) while waiting

– Rescue team must get casualties out speedily. Only workers trained in rescue can enter the space for the purpose of rescue.

27

PREPARATION FOR ENTRY

Step 10: Work Completed

• Housekeeping

• Debriefing

• De-isolate, de-energize

• PTW closed

• Hand-over

28

PREPARATION FOR ENTRY

RESCUE AND EMERGENCY PROCEDURE

• The employer has to establish a rescue and first aid procedure and provision of rescue equipment

• Rescue procedure should consider:

– The shape and size of confined space

– The nature of task to be performed

– Obstacles within confined space

– Size and position of the mean of ingress and egress

– Number of persons in confined space

– The number of stand-by persons required

29

• Created specifically for each potential accident or emergency • Alarm:

– First alert of an emergency. – Different types of alarms. – Flashing lights – in noisy locations – Automatic alarms

• Emergency Action: sequence of things to be done, decisions to be made; flow chart, check lists prepared for reference.

• Evacuation, Rescue, First Aid • Communication : Coordination and flow of information; only

one person in charge. Communication with involved parties and with BOMBA, hospital etc

30

RESCUE AND EMERGENCY PROCEDURE

• An accident in a confined space

demands immediate action. One of

the most important goals of confined

space rescue training is learning to

work as a team.

31

Mechanical equipment is required for rescue when the

depth is more than 1.5 m

RESCUE AND EMERGENCY PROCEDURE

EMERGENCY AND RESCUE EQUIPMENT

• Suitable clothing • Breathing and resuscitation apparatus

+ O2 • Safety harness + rope + tripod • Torches, lamps • Breathing apparatus – SCBA • First aid equipment • Audible alarm • Communication sets • Others…

32

RESCUE AND EMERGENCY PROCEDURE

SHORTFALLS

• Any system is only as good as the people who use it

• Some operators may be required to sign hundreds of PTW documents at the start of shifts. It is so easy to fill out a tick box, and not check it out at all, physically.

• Two thousand years ago workers were dying in confined spaces due to asphyxiation. Sadly today, it is still happening.

• Technological advances can and should stop this from happening, but cost constraints mean that these equipment are often not made available.
