*As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives
sufficient view of the weld zone without going below the minimum.

1.6 Protective Clothing

Like other jobs or careers, welders must wear suitable protective equipment. In
general, Personal Protective Equipment (PPE) must protect against hazards
such as burns, sparks, spatter, electric shock, and radiation. The use of PPE is a
good safe practice and may be required by regulatory agencies.
•
Wear clothing made from heavyweight, tightly woven, 100% wool or cotton
to protect from UV radiation, hot metal, sparks and open flames. Flame
retardant treatments become less effective with repeated laundering.
•
Keep clothing clean and free of oils, greases and combustible contaminants.
•
Wear long-sleeved shirts with buttoned cuffs and a collar to protect the neck.
Dark colors prevent light reflection.
•
Tape shirt pockets closed to avoid collecting sparks or hot metal or keep
them covered with flaps.
