
ARC RAYS can burn

Avoid eye and body damage. Arc rays and infrared radiation can cause
injury to the eyes and burn the skin. Wear ANSI approved eye and body
protection. Do not allow viewing by visitors without proper eye and body
protection.

Use a shield with the proper filter and cover plates to protect your eyes
from sparks and the rays of the arc when plasma cutting or observing open arc plasma cutting.

Use suitable clothing made from durable flame-resistant material to protect your skin and that of
your helpers from the arc rays.

Protect other nearby personnel with suitable, non-flammable screening and/or warn them not to
watch the arc nor expose themselves to the arc rays or to hot spatter or metal.

WELDING SPARKS can cause fire or explosion

Remove fire hazards from the cutting area. If this is not possible, cover
them to prevent the welding sparks from starting a fire. Remember that welding
sparks and hot materials from cutting can easily go through small cracks and
openings to adjacent areas. Avoid cutting near hydraulic lines. Have a fire
extinguisher readily available. Do not operate the electric arc welder in areas where
flammable or explosive vapors are present.

Where compressed gases are to be used at the job site, special precautions should be used to
prevent hazardous situations.

Do not heat, cut or weld tanks, drums or containers until the proper steps have been taken to
insure that such procedures will not cause flammable or toxic vapors from substances inside.
They can cause an explosion even though they have been “cleaned”.

Always keep a fire extinguisher nearby while welding.

Use welding blankets to protect painted surfaces, dashboards, engines, etc.

Please make sure there are no combustible items around your welding area.

CYLINDER may explode if damaged

Use only compressed gas cylinders containing the correct shielding 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 should be located:

Away from areas where they may be struck or subjected to physical damage.

A safe distance from arc welding or cutting operations and any other source of heat, sparks,
or flame.

Never allow any 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.
