3.4.1 Protective Clothing
Wear gloves, suitable long sleeved shirts/jackets, safety shoes, welding
helmet, and other articles needed to shield the skin and to prevent injury
from arc burns. Wear ear plugs if welding overhead or in a confined
space. Wear a hard hat if others are working above you.
3.4.2 Eye and Head Protection
Protect your eyes and head by wearing a welding helmet fitted with a
double lens; use a clear lens outside and a colored, welding filter inside.
Use at least a number 10 filter. If welding over 100 amps, use a number
12 filter (or darker as appropriate).
Always lower the helmet before striking the arc. Wear safety glasses with
side shields under the helmet to protect the eyes from flying particles and
side arc flashes when the helmet is up.
Protect the eyes of other people in the area by use of opaque, non-
reflecting and nonflammable screens around your welding station. Allow
good air circulation, especially at floor level. Do not permit anyone to
view the arc unless he uses a correct hand shield, or helmet.
3.5 TOXIC FUME PREVENTION:
Breathing the fumes created during welding or cutting can cause illness or death
if adequate ventilation is not provided. Provide ventilation in accordance with
ANSI Standard Z49.1.
Some Fume Sources are:
3.5.1 Weldments
Metals containing lead, cadmium, zinc, mercury and beryllium can
produce harmful toxic fumes when welded or cut. Adequate local exhaust
ventilation must be used for the operator and persons in the area.
3.5.2 Coated Weldments
Remove coatings that emit toxic fumes when heated or use exhaust
ventilation and/or an air-supplied respirator.
3.5.3 Vessels That Have Contained Toxic Materials
Vapors from chlorinated solvents can be decomposed by the arc to form
the highly toxic gas called PHOSGENE or other damaging products. The
ultraviolet radiant energy of the arc can also decompose trichloroethylene
and perchloroethylene vapors to form PHOSGENE. Do not weld or cut
unless such containers have been thoroughly cleaned following AWS
Standard A6.0.
