71. What is the different Hazardous Area Classification? (as per KOC) What you mean by Hazardous Area? What is Zone 0, 1 and 2. 

Hazardous Area: Hazardous area is the zone in which a flammable atmosphere may be present during normal operation or under abnormal conditions. Classification of Hazardous Area: 

Zone - 0: Zone in which a flammable atmosphere is continuously present or present for a long period. (Typically more than 1000 hours/year.) 

Zone - 1: Zone in which a flammable atmosphere is likely to occur in normal operations. (Typically 10 to 1000 hours/year) 

Zone- 2: Zone in which a flammable atmosphere is not likely to occur under normal operations and if it occurs, it will only exist for a short time. (Typically less than 10 hours/year)


72. Incase of Fire, Accident, Gas leak or Explosion what you will do? 

How you will safeguard your people at the site incase of any leak? Whom & How do you communicate this emergency.

 Inform to nearest fire station / Burgan fire station with clear details about the incident and emergency evacuation plan will be following up.

 All will wait in the safe area until further instruction come from the emergency officer/KOC for either to return back to the work or to a safe area.

73. Enlist precaution to be taken prior to start the WELDING and GRINGDING works on the pipeline inside GC & why it is required? 
OR 
Explain Safety Precaution for a Hot Work? OR What are the safety precautions you will take for a hot work? Following precaution should be taken during Welding / Hot Work.

 Hot Work will start with a valid hot work permit.

 If it is inside GC or Refinery then need to cover the welding point with proper fire blanket.

 Frequent gas test to be carried out

 Wet the area with water and pressurized firewater hose to be kept near the hot work area.

 Combustible materials to be removed from welding point.

 Keep the certified and valid fire extinguisher near the hot work area.

 Trained and certified fire watcher should be present.

 Equipment, which will be used for hot work to be inspected before starting up the job.

 All welding machine must be connected with GFCI (Ground Fault Circuit Interrupter) or ELCB (Earth Leakage Circuit Breaker) and approved spark arrester.

 All welding machines must be ground with static-earthing device.

 All cable must be properly insulated and electrode holder, plugs and sockets must be in good condition.

 The equipment or pipe, spool should be supported on a secured and firm base during welding or grinding.

 All valves, flanges, drains, canals etc. where gas leaks or presence of flammable atmosphere is possible should be covered.


74. What are the Safety Precautions taken GAS WELDING & CUTTING?

 Any hot work will start with a valid hot work permit.

 Frequent gas test to be carried out.

 In a gas welding or cutting operations, the oxyacetylene flames shall be
