Wear ear plugs to protect ears from sparks. Where work permits, the operator should be enclosed in an individual
boothpainted with a lowreectivematerialsuch as zinc oxide.See safetyand operatingreferences1, 2, and3.
WELDING SPARKS CAN CAUSE FIRES AND EXPLOSIONS
Combustiblesreachedbythearc,ame,yingsparks,hotslag,andheatedmaterialscancausere
and explosions. Remove combustibles from the work area and/or provide a re watch. Avoid oily
or greasy clothing as a spark may ignite them. Have a re extinguisher nearby, and know how to
use it. Ifwelding/cutting isto bedone ona metal wall,partition, ceiling, or roof, precautionsmust
be taken to prevent ignition of nearby combustibles on the other side. Do not weld/cut containers
that have held combustibles. All hollow spaces, cavities, and containers should be vented prior to
welding/cutting to permit the escape of air or gases. Purging with inert gas is recommended. Never use oxygen in a
weldingtorch.Useonlyinertgasesorinertgasmixesasrequiredbytheprocess.Useofcombustiblecompressedgases
can cause explosions resulting in personal injury or death. Arcing against any compressed gas cylinder can cause
cylinder damage or explosion. See safety and operating references 1, 2, 5, 7, and 8.
NOISE CAN DAMAGE HEARING
Noise from the air carbon-arc process can damage your hearing.Wear protective hearing devices to
ensure protection when noise levels exceed OHSA standards. Adequate hearing protection devices
must be worn by operators and surrounding personnel to ensure personal protection against noise.
