The Health and Safety Executive (HSE) issued a bulletin (No. STSU1-2019) on the 7th February 2019 warning of new scientific evidence from the International Agency for Research on Cancer that exposure to mild steel welding fumes can cause lung cancer and possibly kidney cancer in humans.
The Workplace Health Expert Committee has endorsed the reclassification of mild steel welding fume as a human carcinogen.
Subsequently and with immediate effect, there is a strengthening of HSE’s enforcement expectation for all welding fume, including mild steel welding; because general ventilation does not achieve the necessary control.
The Health and Safety Executive safety alert can be viewed here: http://www.hse.gov.uk/safetybulletins/mild-steel-welding-fume.htm
Immediate action is required now to ensure that employees, workers, employers, owners, managers and directors or contractors’ undertaking welding activities in any industry are aware of the risks, expectations, outcomes and actions that are now required, as detailed below:
-Control of the cancer risk will require suitable engineering controls for all welding activities indoors e.g. Local Exhaust Ventilation (LEV). Extraction will also control exposure to manganese, which is present in mild steel welding fume, which can cause neurological effects similar to Parkinson’s disease.
-Where LEV alone does not adequately control exposure, it should be supplemented by adequate and suitable respiratory protective equipment (RPE) to protect against the residual fume.
-Appropriate RPE should be provided for welding outdoors. You should ensure welders are suitably instructed and trained in the use of these controls.
-Regardless of duration, HSE will no longer accept any welding undertaken without any 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.
-Make sure exposure to any welding fume released is adequately controlled using engineering controls (typically LEV).
-Make sure suitable controls are provided for all welding activities, irrelevant of duration. This includes welding outdoors.
-Where engineering controls alone cannot control exposure, then adequate and suitable RPE should be provided to control risk from any residual fume.
-Make sure all engineering controls are correctly used, suitably maintained and are subject to thorough examination and test where required.
-Make sure any RPE is subject to an RPE programme. An RPE programme encapsulates all the elements of RPE use you need to ensure that your RPE is effective in protecting the wearer.
Clearly welding and cutting can be extremely dangerous if you are not correctly protected, there are a variety of chemicals which when melted can create dangerous substances. The dangerous substances and radiation generated during the welding process can be extremely hazardous to a welders’ health.
There are a variety of brands including Kemper, Parweld and Electac which provide protective equipment for welders. Our largest supplier of welding and cutting protection is Kemper who are pioneers and a leader in the technology of the welding smoke extraction industry
