1-2. Arc Welding Hazards
Only qualified persons should install, operate, maintain, and repair this equipment. A
qualified person is defined as one who, by possession of a recognized degree, certificate,
or professional standing, or who by extensive knowledge, training and experience, has
successfully demonstrated ability to solve or resolve problems relating to the subject
matter, the work, or the project and has received safety training to recognize and avoid
the hazards involved.
Arc rays from the welding process produce intense visible and invisible (ultravio-
let and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.
Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when
welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Refer to Lens
Shade Selection table in Section 1-4.
Wear approved safety glasses with side shields under your helmet.
Use protective screens or barriers to protect others from flash, glare, and sparks; warn
others not to watch the arc.
Wear body protection made from durable, flame − resistant material (leather, heavy cotton,
wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
•
Before welding, adjust the auto-darkening lens sensitivity setting to meet the application.
•
Stop welding immediately if the auto-darkening lens does not darken when the arc is struck.
ARC RAYS can burn eyes and skin.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
