20 FM Global Hot Work Losses ( ) How many of these were Hot Work Permit System No. of Losses Est. Gross 2010$ preventable? Average Permit System 192 $1,040,384,613 $5,418,670 Deficient 100% Permit System 9 $2,816,027 $312,892 Effective Grand Total 201 $1,043,200,639 $5,190,053 The average loss where Hot Work Permit System was deficient was 17 times larger than the average loss where Hot Work Permit System was effective.

36 Key Steps Part 2 Fire Watch Signoff Final Checkup

37 Leading Ignition Sources Controlled by Contractors at the Time of Loss, FM Global loss history shows the risk of fire more than DOUBLES when 7% 5% 4% 3% Hot Work 7% Electricity Arson Smoking contractors perform hot work without supervision. Contractors account for 74% 74% of hot work losses. (Total Losses > US$1.1Billion) Hot Surface Burner Flame

38 Hot Work Control Responsibilities Before Fire Safety Supervisor Decides if there is a safer way to complete the job Determines if hot work can be performed in area identified Verifies precautions Authorizes and signs permits Communicates to other employees Fire Watch Prepared to continuously monitor area for 60 minutes after the hot work is complete Ready to sound alarm and use an extinguisher Trained to Respond

39 Hot Work Control Responsibilities - During Fire Watch Maintain constant watch of area Watch for stray sparks and smoldering Stop hot work if unsafe conditions develop Provide initial fire response if necessary Be prepared to sound alarms and notify emergency personnel

41 Leading Ignition Sources Controlled by Contractors at the Time of Loss, % 5% 4% 3% Hot Work 7% Electricity Arson Smoking 74% Hot Surface Burner Flame (Total Losses > US$1.1Billion)

42 Fire Watch Hot Work Control Responsibilities - After Remains in the area for 60 minutes and inspects the area for smoldering Signs permit and leaves it posted for the 3-hr monitoring period Monitor for 3 hrs after completion - methods of monitoring can be smoke detectors, security rounds, security cameras, operators in area Fire Safety Supervisor 4 hrs. after hot work Conducts final inspections of area Signs off on permit retains permit for records
