745 Welding, Cutting, and Brazing Safety

Decomposition Products

Manufacturer's Instructions: When using cleaning materials that are possibly toxic or flammable, appropriate manufacturer precautions and instructions must be followed.

Degreasing: Degreasing and other cleaning operations involving chlorinated hydrocarbons must be located so that no vapors from these operations will reach or be drawn into the atmosphere surrounding any welding operation. In addition, keep trichloroethylene and perchloroethylene out of atmospheres penetrated by the ultraviolet radiation of gas-shielded welding operations.

Stainless Steel: Use mechanical ventilation that is adequate to remove the fumes generated by oxygen cutting when using either a chemical flux, or iron powder, or gas-shielded arc cutting of stainless steel.

First-aid Equipment

First-aid equipment must be available at all times. Report all injuries as soon as possible for medical attention. Perform necessary first aid until medical attention is available.
