Welding Fume Exposure
Construction and general industry · Ver en español
Talking points
- Welding fumes contain a mixture of metals and gases that can cause serious lung disease, neurological damage (from manganese), and cancer (from hexavalent chromium).
- Ventilation — local exhaust or general mechanical — is required whenever welding is performed in enclosed or confined areas.
- Welding on stainless steel, galvanized steel, or painted surfaces produces especially hazardous fumes. Respiratory protection is often required in addition to ventilation.
- The PEL for hexavalent chromium is 5 µg/m³ — extremely low. Even short-duration stainless steel welding can exceed this limit without proper controls.
- Position yourself upwind or to the side of the weld plume whenever possible. Your welding helmet does not protect you from fume inhalation.
Ask the crew
What material are we welding today, and do we have adequate ventilation — or do we need respiratory protection?

A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
