The workplace exposure standard (WES) for aluminium welding fumes has been reduced from 5 mg/m³ to 1 mg/m³, measured as an 8-hour time-weighted average. This change is now in effect.
Aluminium welding, commonly used in boat building and repair, produces hazardous fumes that can harm workers' health. This reduction aligns the WES for aluminium welding fumes with the existing standard for welding fumes (not otherwise classified), providing better protection for workers.
What Persons Conducting a Business or Undertaking need to do
- Review and update welding fume controls to ensure exposure remains below the new 1 mg/m³ limit. Take all reasonably practicable steps to eliminate or minimise risks.
- Consider respiratory protective equipment (RPE) when determining compliance, but only after implementing all higher-level controls in the hierarchy of risk management.
- Seek expert advice, such as from an occupational hygienist, if you are unsure whether your controls meet the new standard.
