According to International Agency for Research on Cancer (IARC), all welding fumes are Group 1 carcinogenic to humans. Element’s welding fume exposure monitoring services help monitor your workers’ exposure to harmful welding fumes and ensure that you comply with the COSHH Regulations.
What is welding fume monitoring?
Welding fume monitoring measures personal exposure to airborne concentrations of hazardous substances emitted during the welding process, assesses the risks, and provides recommendations for appropriate control measures.
Is exposure to welding fumes harmful?
Research by the IARC indicates that exposure to all types of welding fumes, including fume from mild steel welding can cause several health conditions including lung cancer, kidney cancer, COPD, asthma, metal fume fever, siderosis, stomach ulcers, renal damage, and neurological effects similar to Parkinson’s disease (Manganism).
All welding fume from all types of metal should be treated as capable of causing cancer, and the IARC has reclassified all welding fume, including fume from mild steel welding, as Group 1 carcinogenic to humans.
What are welding fumes exposure limits?
The Health & Safety Executive document EH40 contains a list of Workplace Exposure Limits (WELs) for use with COSHH.
- Inhalable Fraction- Respirable Fraction
0.2 mg/m30.05 mg/m3
|Nitrogen Oxide||2.5 mg/m3|
1.91 mg/m3 STEL
||0.4 mg/m3 STEL
Some substances have Short Term Exposure Limits (STEL) where concentrations must not exceed the limit over 15 minutes.
How does this affect you?
All businesses undertaking welding activities should ensure workers are protected from the inhalation risk of welding fumes by providing effective engineering controls for risk mitigation. For example, Local Exhaust Ventilation (LEV) when provided and correctly applied, will control fumes and gases arising from welding activities.
Where engineering controls are not sufficient to control all fume exposure, adequate and suitable respiratory protective equipment (RPE) is also required to manage risk from the residual fume, including welding outdoors. You should ensure welders are suitably instructed and trained in the use of these controls.
Regardless of duration, the UK HSE will no longer accept any welding undertaken without suitable exposure control measures in place, as there is no known level of safe exposure. Risk assessments should reflect the change in the expected control measures.
