Under the work health and safety legislation, a person conducting a business or undertaking (PCBU) must ensure no person at a workplace is exposed to an airborne contaminant above the concentration listed in the Workplace exposure standards (WES) for airborne contaminants

To protect workers and others from the adverse health risks of welding fumes, PCBUs must ensure exposure levels to welding fumes and other chemicals released during welding processes are below their respective exposure limits.

In addition, reasonably practicable steps must be undertaken to eliminate or minimise the risks of exposure. The Welding processes: Code of practice provides guidance to help manage these risks.
