Hot Work Fire Prevention
What is Hot Work?
Hot work involves any operation that where heat is produced. This includes open flames, sparks, hot slag, etc. Specific examples include cutting, welding, brazing, soldering, grinding, sawing, etc. Open flame torches and other heat producing devices are also used for the application of some roof coverings as well
The following are tips to help prevent a hot work related fire from
occurring:
First consider another alternative to a hot work
operation. For example, consider cutting with hand or electric saws or pipe
cutters rather than torches. Consider using mechanical means of joining nuts and
bolts, screwed fittings or couplings. Consider installing threaded pipe instead
of welded or soldered pipe.
Do not conduct hot work in any area involving an
operation or processes such as those involving flammable liquids, gases and
dusts. If there are no alternative methods, first eliminate the hazardous
operation or process.
Identify combustible construction. Pay particular
attention to concealed areas behind walls, above ceilings or beneath roofs.
Consider insulating materials and finishes.
Relocate or move combustible materials and storage prior
to the start of work.
Maintain an area of at least 35 feet that is clear of
combustibles in all directions.
Shield combustible flooring with wet sand, fire
retardant tarpaulins or sheet metal.
Block off any duct openings where sparks can spread.
If your facility is (or is to be) protected with an
automatic sprinkler system, be sure it is installed and in service prior to the
start of work.
Portable extinguishers should be available in the hot
work area.
A person (or persons) should be designated as a fire
watch. This person should be positioned near the person doing the hot work.
This individual and possibly others as deemed necessary will watch for possible
ignition and stop hot work operations if necessary. Most importantly, this
person will ensure all the procedures are followed.
After work is complete, a fire watch should continue to
check the area for a period of no less than three hours.
A written policy and use of a "Permit Form -
Checklist" should be used established to help ensure the above tips are
considered for each and every hot work operation.
