Cutting flame and sparks can cause FIRE OR EXPLOSION:
• Fire and explosion can be caused by hot slag, sparks, oxygen fueled cutting flame, or the plasma arc.
• Have a fire extinguisher readily available. Provide a fire watch when working in an area where fire hazards
may exist.
• When not cutting or gouging, make certain no part of the electrode circuit is touching the work or ground.
Accidental contact can cause overheating and create a fire hazard.
• Be sure there are no combustible or flammable materials in the workplace. Any material that cannot be
removed must be protected.
• Sparks and hot materials from cutting or gouging can easily go through small cracks and openings to
adjacent areas.
• Avoid cutting or gouging near hydraulic lines.
• Do not cut or gouge tanks, drums, or containers until the proper steps have been taken to ensure
that flammable and/or toxic vapors from substances inside have been completely removed. They can
cause an explosion even though they have been "cleaned." For information purchase "Recommended
Safe Practices for the Preparation for Welding and Cutting of Containers and Piping That Have Held
Hazardous Substances", AWS F4.1 from the American Welding Society

historical).
• Vent hollow castings or containers before heating, cutting, or gouging. They may explode.
• Do not add fuel to engine-driven equipment near an area where plasma cutting or gouging is being done.
• Connect the work cable to the work as close to the cutting or gouging area as practical. Work cables
connected to the building framework or other locations away from the cutting or gouging area increase the
possibility of the current passing through lifting chains, crane cablesm, or other alternate circuits. This can
create fire hazards or overheat lifting chains or cables until they fail.
• Hydrogen gas may be formed and trapped under aluminum work pieces when they are cut underwater or
while using a water table. DO NOT cut aluminum alloys underwater or on a water table unless the hydrogen
gas can be eliminated or dissipated. Trapped hydrogen gas that is ignited will cause an explosion.
• Read and follow NFPA 51B " Standard for Fire Prevention During Welding, Cutting and Other Hot Work,"
available from NFPA, 1 Batterymarch Park, PO box 9101, Quincy, Ma 022690-9101.
CYLINDER may EXPLODE if damaged:
• Use only compressed gas cylinders containing the correct gas for the process used and properly operating
regulators designed for the gas and pressure used. All hoses, fittings, etc. should be suitable for the
application and maintained in good condition.
• Always keep cylinders in an upright position, securely chained to an undercarriage or fixed support.
• Cylinders must be located away from areas where they may be struck or subjected to physical damage.
• They must be a safe distance from plasma cutting or gouging, arc welding operations and any other source
of heat, sparks, or flame.
• Never allow any part of the electrode, torch, or any other electrically "hot" parts to touch a cylinder.
• Keep your head and face away from the cylinder valve outlet when opening the cylinder valve.
• Valve protection caps should always be in place and hand tight except when the cylinder is in use or
connected for use.
Read and follow the instructions on compressed gas cylinders, associated equipment, and CGA publication P-1,
"Standard for Safe Handling of Compressed Gases in Cylinders,"available from the Compressed Gas Association,
1235 Jefferson Davis Highway, Arlington, VA 22202.

AIR LINES UNDER PRESSURE:
• Some tools use compressed air or gas. Flexible tubing (lines) bring the pressurized air and gas to the machine.
Inspect all lines prior to machine operation. Damaged lines should be replaced prior to operation.
• Hot sparks, flying debris, or wear can melt, burn, or puncture these lines and cause damage to the operator.
• Route air and gas lines to keep away from traffic and from underfoot.
