Decomposition Products
Manufacturer's Instructions: In the use of cleaning materials, because of their possible toxicity or flammability, appropriate precautions such as manufacturers instructions must be followed.
Degreasing: Degreasing and other cleaning operations involving chlorinated hydrocarbons must be located so 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.
