•
Wear dark safety glasses or goggles with side shields. Replace glasses/goggles when lenses are
pitted or broken.
•
Warn others not to look directly at the arc unless wearing appropriate safety glasses.
•
Prepare cutting area to reduce reflection and transmission of ultraviolet light.
•
Paint walls and other surfaces with dark colors to reduce reflections.
•
Install protective screens or curtains to reduce ultraviolet transmission.
BURN HAZARD.
The plasma and oxy-fuel cutting processes can cause severe burns during or after the cutting
sequence.
•
Keep hands clear of torch during and after operation. Allow torch ample time to cool.
•
Do not touch plate or cut parts immediately after cutting. Allow metal time to cool, or douse with
water. Wear gauntlet style gloves when picking up cut parts.
•
Plasma arcs can cause burns. Keep yourself and others away from the plasma process during
operation.
NOISE HAZARD.
Noise generated from plasma and oxy-fuel cutting can damage your hearing.
•
Wear proper hearing protection.
EXPLOSION HAZARD.
Oxy-fuel torches can create explosive gas pockets if flowing gas is not burned.
•
Never leave gases turned on if a torch fails to ignite.
•
If unignited gas has been flowing from a torch more than a few seconds, allow gas time to
dissipate before re-igniting the torch.
•
Explosive gas mixtures can accumulate underneath plate and inside cutting table. Use fans to
dissipate any possible gas pockets.
•
If plasma cutting Aluminum on a water table, hydrogen gas pockets may be formed below the
plate. These pockets will explode if ignited by sparks or plasma arc. Explosions can cause serious
personal injury or death.
•
If cutting Aluminum over a water table, use fans to circulate air between plate and water surface.
•
If water table has not been used for several hours, vibrate or jolt it to break up hydrogen pockets.
•
Clean slag (especially fine particles) from bottom of water table frequently.
•
All hoses and cables should be inspected regularly & replaced if necessary.
ALUMINUM EXPLOSION HAZARD.
Certain molten aluminum lithium (AlLi) alloys can cause explosions when plasma cut in the presence of
water.
•
Do NOT plasma cut AlLi alloys with or near water. These alloys should only be dry cut on a dry
table.
•
Do NOT dry cut over water.
