SET-UP AND SAFE OPERATING PROCEDURES
2-5
0056-0114
Flying sparks can travel up to a distance of 35 feet or more. Remove all combustible materials 4.
away from areas where oxy-fuel operations are being performed.
Operators may not become aware of a fire starting while operating apparatus. Their vision 5.
is seriously hampered by the welding goggles and dark lenses. Depending upon the
circumstances of the work location, it may be advisable to have a fire watcher to operate
an extinguisher and sound a fire alarm in case of a fire.
Keep an approved fire extinguisher of the proper size and type in the work area. 6.
Inspect it regularly to ensure that it is in proper working order. Know how to use the fire
extinguisher.
Use heat resistant shields or other approved material to protect nearby surfaces, ceilings 7.
and equipment from sparks and hot metal.
Only use oxy-fuel equipment with the fuel gas it was designed for.8.
After the equipment has been properly set up, open the acetylene cylinder valve approximately 9.
3/4 of a turn, but NO MORE than 1-1/2 turns. Keep the cylinder wrench, if one is required,
on the cylinder valve so the cylinder may be turned off quickly if it becomes necessary.
All gases 10. EXCEPT ACETYLENE: Open the fuel gas cylinder valve completely to seal the
cylinder back seal packing.
Never test for gas leaks with a flame. Use an approved leak-detector solution.11.
Never perform welding, cutting, and heating operations on a container that has held toxic 12.
or combustible liquids or vapors.
Never perform welding, cutting, and heating operations in an area containing combustible 13.
vapors, flammable liquids, or explosive dust.
Never perform welding, cutting, and heating operations on a closed container or vessel, 14.
which may explode when heated.
Avoid operating the equipment in rooms with sprinkler systems unless there is sufficient 15.
ventilation to keep the area cool.
When the work is complete, inspect the area for possible fires or smoldering materials.16.
2.04 CYLINDERS
All Government and insurance regulations relating to the storage of oxygen, acetylene and LPG
cylinders should be closely observed.
Industrial gas cylinders are made to rigid specifications and are inspected each time they are refilled
by your supplier. They are safe if properly handled.
For additional information on the safe handling of gas cylinders, contact your gas supplier or refer to the
Compressed Gas Association publication P-1, “Safe Handling of Compressed Gases in Containers”.
Keep all cylinders, empty or full, away from radiators, furnaces and other sources of heat.•
Avoid contact with electrical circuits.•
