FUME HAZARDS 1.5
WARNING: FUMES, GASES, AND VAPORS CAN CAUSE
DISCOMFORT, ILLNESS, AND DEATH! To reduce risk of
discomfort, illness, or death, read, understand, and follow the
following safety instructions. In addition, make certain that anyone
else that uses this welding equipment or is a bystander in the
welding area, understands and follows these safety instructions as
well.
Do not weld in an area until it is checked for adequate ventilation as •
described in ANSI standard #Z49.1. If ventilation is not adequate to
exchange all fumes and gasses generated during the welding process
withfreshair,donotweldunlessyou(thewelder)andallbystandersare
wearing air-supplied respirators.
Do not heat metals coated with, or that contain, materials that produce •
toxicfumes(suchasgalvanizedsteel),unlessthecoatingisremoved.
Make certain the area is well ventilated, and the operator and all
bystanders are wearing air-supplied respirators.
Do not weld, cut, or heat lead, zinc, cadmium, mercury, beryllium, or •
similar metals without seeking professional advice and inspection of
the ventilation of the welding area. These metals produce EXTREMELY
TOXIC fumes that can cause discomfort, illness, and death.
Do not weld or cut in areas that are near chlorinated solvents. •
Vapors from chlorinated hydrocarbons, such as trichloroethylene and
perchloroethylene, can be decomposed by the heat of an electric arc or
its ultraviolet radiation. These actions can cause PHOSGENE, a HIGHLY
TOXIC gas to form, along with other lung and eye-irritating gases. Do not
weld or cut where these solvent vapors can be drawn into the work area
or where the ultraviolet radiation can penetrate to areas containing even
very small amounts of these vapors.
Donotweldinaconnedareaunlessitisbeingventilatedandthe•
operator(andanyoneelseinthearea)iswearinganair-supplied
respirator.
Stop welding immediately if you develop momentary eye, nose, or •
throat irritation as this indicates inadequate ventilation. Stop work and
take necessary steps to improve ventilation in the welding area. Do not
resume welding if physical discomfort persists.
