  8. 8. Shall be carried out prior to work involvingentry into confined spaceShall be carried out by assessor if there is anychemicals hazardous to health used in theconfined spaceTo be revised whenever there is evidence toindicate the assessment is no longer valid /every 5 years / when directed by DG, DDG orDirector of DOSHAppendix A – example of risk assessmentAppendix B – sample of risk assessment form
  9. 9. Risk assessment Nature Emergency of Actual method Hazards and rescueconfined Factors selected and plan procedure identified space proposed number of AE/SP duration Proposed operations and work procedures status of fitness and training Steps needed to bring c/space to atmospheric pressure adequacy of instructions Cleaning and purging availability and adequacy of PPE Hot work method rescue equipment Soundness and security of overall structure, and the need for illumination and visibility Need for additional protective measures Method of ventilation Evaluation of gases / substances
  10. 10. Specifying acceptable entry conditionsVerifying RISK (Gas CONTROL Isolatingtesting) (3) Purging, inerting, flushing or ventilating
  11. 11. At least one SP outside the confined spaceFor monitoring of multiple confined spaces by a singleSP, programme shall include means and procedures toenable SP to respond to an emergency affecting one ormore of the confined spaces monitored withoutdistraction from the SP’s responsibilitiesWritten system for preparation, issuance,implementation and cancellation of PTW
  12. 12. Warning signages shall be posted atconspicuous places when work is carried outafter the issuance of PTWAll employees who are involved in confinedspace operation shall undergo training onconfined space safety course approved by DGand passed the examination

  14. 14. Employer shall designate and identify the dutiesof employees to be AE/SP/ES/AGT/PI or otherrelated personnel in entry operation These personnel shall carry out their duties as in specifiedEmployer shall provide and brief contractorswith information about the confined spacehazards, safety rules and emergency procedures
  15. 15. Procedures shall be developed andimplemented when employees are working atthe same time as AEs in a confined space, sothat employees of 1 contractor do not endangerthe employees of any other contractorProcedures for concluding the entry shall bedeveloped and implementedDebriefing shall be conducted after the closing ofPTW
  16. 16. Programme shall be reviewed whenemployer has reasons to believe thatmeasures taken under it may not protectemployees and that there is a need torevise the programme to correctdeficiencies found to exist beforesubsequent entries are authorised
  17. 17. Shall contain the following information: Confined space to be entered Purpose of entry Date and the authorised duration of the permit AEs within the confined space, by name / by such other means as will enable the SP to determine quickly and accurately, for the duration of the PTW, which AEs are inside the confined space Permit issuer who signs the PTW ES Hazards of the confined space to be entered Measures used to isolate the confined space The acceptable entry conditions --> refer USECHH Reg, 2000
  18. 18. Shall contain the following information: Results of initial and periodic tests performed and accompanied by the names of AGTs and by an indication of what tests were performed Communication procedures used by AE and SP Equipment, such as PPE, testing equipment, communication equipment, emergency alarm system and rescue equipment to be provided Any information which is necessary to be included SP and rescue arrangements Any additional permit, such as for hot work that has been issued to authorise work in the confined space Appendix C – additional info on hot work Appendix D – example of PTW
  19. 19. Prevent accidental introduction of hazardousmaterial / substances into the confined spaceDe-energise and lock out or de-energise and tagout all machinery that has moving partsIsolate any other external energy sources
  20. 20. Initial cleaningVentilation Requirements Purging to ensure safety of atmosphere Retest Testing and/or and monitoring evaluation
  21. 21. Shall only be allowed under the following conditions… Atmosphere inside the confined space could not be brought to safe working conditions despite all reasonable effort made to purge, clean and ventilate the space Nature of work procedure within the confined space is likely to degrade or contaminate the atmosphere in the confined space Introduction of air into the confined space would pose additional risk to health and safety aspect of AE and the activities carried out therein / would detrimentally affect the product, equipment or other substances contained in the confined space
  22. 22. AE entering shall use SCBA, compressed airlinebreathing apparatus or special life supporting system,depending on the nature of works and hazardsinvolvedContinuous gas monitoring for LEL shall be carried outduring entry Proper type of explosimeter that can give true indication of the flammable gas level shall be used Hot work shall not be undertaken if explosimeter reading > 1% LEL Confined space shall not be entered if explosimeter reading > 10% LEL (If entry is still necessary, appropriate positive pressure air-supplied breathing apparatus shall be used and entry shall be made under inert atmosphere as in slide # 26)
  23. 23. Additional requirements for rescue plan: AE shall wear a safety harness with lifeline attached to facilitate rescue operation in an emergency situation Appropriate number of air-supplied breathing apparatus shall be put on standby outside the confined space for use by the rescuer Min. rescuer = 2 AE shall carry with him an escape set / additional supply of breathing air cylinder for use in case of emergency In certain circumstances, such as work inside spheres / tall columns, it may be necessary to use a safety harness in conjunction with a special winch / pulley / additional manpower Shall be set up before entry starts
  24. 24. Where compressed airline breathing apparatus is used, theairline coupling shall operate on breathing air system usingdedicated coupling with double locking mechanism. Coupling shall not be compatible with N2, O2 or other gas systemsConditions of compressed airline system such as the hoses andfitting, air purifying element (filter), pressure relief valve,pressure regulator, pressure gauge and the compressed aircylinder or compressor shall be monitored at all times by trainedpersonnel to ensure continuous air supply whenever the airlinesystem is in use during entryNumber of AE permitted to enter a confined space shall belimited according to the available space, the number of escaperoutes and the rescue facilities
  25. 25. Purpose for introduction of inert atmosphere insideconfined space: Prevention of flammable and explosive conditions through elimination of fuel, air or O2 and energy in the form of heat, spark or flame Prevention of chemical reaction or oxidation of substances contained in the confined space Prevention of other hazardous conditions through elimination of corrosive, toxic, infectious / harmful gasesSelection and application of inert gas requires carefulmatching of processes and products so as not tointroduce other hazards resulting from chemicalreactions
  26. 26. Special safety considerations: When working near open manhole where inert gas / other asphyxiant gas is used or contained in confined space, area shall be barricaded and warning signage shall be conspicuously posted, and appropriate respiratory protection must be used When working with inert atmosphere containing toxic substances, concentration shall also be measured at locations in close proximity of open manholes outside the confined space If inert gas is constantly introduced and vented, a system shall be established to effectively maintain atmospheric pressure, and to monitor and reduce potential pressure built-up Inert atmosphere is IDLH hence, SP and two other who are dedicated emergency response personnel who is trained in rescue techniques shall be present and equipped with equivalent / superior protective equipment Independent back up supply of inert gas must be provided to allow the confined space to be evacuated and made safe in the event of a loss of primary supply
  27. 27.
