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 confined 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.
