The International Agency for Research on Cancer’s re-classification of welding fume as a Class 1 carcinogen has emphasized the health risks welders face. Previously classified as “possibly carcinogenic to humans,” welders should take every precaution possible to protect their health.

Many manufacturers use one of two options to clear the air of welding fumes – filter the dirty air and recirculate clean air inside the facility, or exhaust the dirty air outside and provide clean replacement air from outside.
