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

Vapors of these solvents are a concern in welding and cutting because the heat and ultraviolet radiation from the arc will decompose the vapors and form highly toxic and irritating phosgene gas.
Chlorinated hydrocarbons
Heat from an electric arc, a steam of ionized gas called plasma, or burning gases to trim metal objects to specific dimensions
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.
Oxygen and fuel gas welding
Welders helmets and respirators are examples of what type of controls?
Personal Protective Equipment
Whenever practicable, all arc welding and cutting operations shall be shielded by noncombustible or flameproof screen which will _____________.
Protect workers from the direct rays of the arc.

Respiratory system
When a structure or pipeline is employed as a ground return circuit, it must be determined that _______________.
The required electrical contact exist at all joist
In arc welding the arc which produces the heat to melt metal produces intense light. This light can be a combination of three forms of non-ionizing radiation known as?

Process in which metals are fused together by heating them with electricity that is generated between an electrode and the surface of the base metal.
Arc welding
The most common and simplest type of welding today is _________.
Arc welding
Before a regulator is removed from a cylinder valve, the cylinder valve must always ____________.
Be closed and the gas released from the regulator
