7. Wear insulated gloves when adjusting
equipment. Power should be shut off
and insulated gloves should
be worn when making any equipment adjustment to assure shock protection.
8. Follow recognized safety standards.
Follow the recommendations in American National Standard
Z49.1, ”Safety in Welding and Cutting,”
available from the American Welding Society, P. O. Box 351040,
Miami, FL 33135, and also the National
Electrical Code, NFPA No. 70, which is available from
the National Fire
Protection Association, Batterymarch Park, Quincy, MA 02269.
ARC RAYS and SPATTER can injure eyes
and burn skin. Wear
correct eye, ear, and body protection. Electric
arc radiation can burn eyes and skin the same way as strong sunlight. Electric
arcs emit both ultraviolet
and infrared rays. Operators, and particularly those people susceptible to sun-
burn, may receive eye
and skin burns after brief exposure to arc rays. Reddening of the skin by ultraviolet
rays becomes apparent
seven or eight hours later. Long exposures may cause a severe skin burn. Eyes
may be severly burned
by both ultraviolet and infrared rays. Hot welding spatter can cause painful skin
burns and perma- nent
eye damage. To
be sure you are fully protected from arc radiation and spatter, follow these precautions:
1. Cover all skin surfaces and wear
safety glasses for protection from arc burns and burns from
sparks or spatter.
Keep sleeves rolled down. Wear gloves and a helmet. Use
correct lens shade to prevent eye
injury. Choose the correct shade from the table below. Observers should also use
proper protection. See
Filter Recommendations on page 5. 2.
Protect against arc flashes, mechanical injury, or other mishaps.
Wear spectacles or goggles with
No. 2 shade filter lens and side shields
inside the welding helmet or hand shield. Helpers and observers
should wear similar protection.
