The Institution of Occupational Safety and Health (IOSH) is urging employers to ensure workers are protected from cancer-causing welding fumes as enforcement of raised control standards take effect this week.
The enforced control measures for welding operations have been introduced by the UK Health and Safety Executive (HSE). It follows an announcement from the International Agency for Research on Cancer (IARC), who have classified welding fumes and UV radiation from welding as Group 1 carcinogens.
IARC published their findings in Lancet Oncology in 2017 in a paper titled ‘Carcinogenicity of welding, molybdenum trioxide, and indium tin oxide’.
The HSE announcement was shared with the Industry and Regulatory Forum on Local Exhaust Ventilation (LEV) earlier this week, which was attended by leading organisations including IOSH, the Chartered Institution of Building Services Engineers, the Institute of Local Exhaust Ventilation Engineers and the British Occupational Hygiene Society.
The raised enforced control standards are highlighted below:
- All forms of welding fume can cause cancer.
- Control is required where:
- Indoor welding tasks require the use of LEV. If LEV is unable to control fume capture then Respiratory Protective Equipment (RPE) is also required.
- Outdoor welding requires use of RPE.
- Enforcement of the raised control standards is with immediate effect under Control of Substances Hazardous to Health (COSHH) Regulation 7.
The HSE will issue a ‘Safety Alert’ in the near future and control requirements will be communicated through the HSE website. The HSE is also currently developing an intervention plan.
Duty holders are advised to follow guidance in the BOHS Welding Fume Control Selector Tool which is available via the Breathe Freely website.
Michael Edwards, IOSH’s Occupational Safety and Health Content Developer, represents the institution on the LEV committee.
He said: “The raised control standards for welding fumes are now in effect for organisations within the UK and will have implications to a whole range of different industries where welding operations occur. Further efforts must be made to protect workers involved in welding as part of their roles.
