OSHA Welding and Cutting

Moving all flammables and combustibles away from the welding area is ____________.

An example of effective fire prevention

Gas welding cylinders should be stored and secured in

Metal cutting

Cylinders may be used as rollers or supports when?

Never

Arc Welding cables in need of repair must _________.

Not be used and effectively repaired by a qualified person or effectively disposed of.

Permissible exposure levels are established by _______ for many compounds to minimize or prevent adverse health exposures.

Occupational Safety and Health Administration (OSHA)

Activity which depends on the heat produced by the combustion of a fuel gas in the presence of oxygen.
