Eye and face protectors for welding and related tasks, such as grinding and chipping, should comply with the requirements of ANSI Z87.1. Look for labels or markings indicating compliance. Depending on the specific work task, appropriate eye/face protection may include safety glasses with side protection (side shields or wrap-around frames), goggles, face shields, welding helmets, curtains, or combinations of the above.
Choose a tight fitting helmet to help reduce light reflection into the helmet through the space between the shell and the head.
Wear the helmet correctly. Do not use it as a hand shield.
Protect the shade lens from impact and sudden temperature changes that could cause it to crack.
Use a cover lens to protect the filter shade lens. Replace the cover lens if it gets scratched or hazy.
Make sure to replace the gasket periodically if your helmet uses one.
Replace the clear retaining lens to protect your eyes from broken pieces.
Clean lenses periodically.
Discard pitted or damaged lenses.
The correct filter shade is selected according to the welding process, wire diameter, and operating current. The table below gives the correct shade numbers for different situations.
ALWAYS use suggested shade numbers instead of minimum shades.
Provide additional task lighting that suits welders' needs.
ALWAYS use the same shade as the welder's if you are directly observing the welding arc.
