The HSE has said it will “no longer accept any welding undertaken without any suitable exposure control measures in place, as there is no known level of safe exposure”. As such, employers found not to be following the guidance can expect an improvement notice as a minimum.

First, make sure to update your risk assessment. The Control of Substances Hazardous to Health Regulations 2002 (COSHH) require employers carry out a suitable and sufficient risk assessment for those exposed to welding fumes and metalwork fluids. The HSE says it expects suitable engineering controls to be in place for all indoor welding activity such as local exhaust ventilation (LEV). Where LEV alone doesn’t adequately control exposure, it should be supplemented by adequate and suitable respiratory protective equipment (RPE) to protect against residual fume. Where LEV is installed, ensure you have had the required statutory thorough examination and test by a competent person, at least every 14 months.

For outdoor welding, inspectors will expect suitable RPE to be used. Workers should be trained to correctly use the provided RPE and LEV – it should be suitable for the task and maintained in good condition.

Exactly what controls are required in managing metalworking fluids will depend on the circumstances. However, as a general rule, work activities and operations should be designed to minimise emissions and contact with metalworking fluids. This may involve enclosing a process or the use of LEV. Where exposure can’t be adequately controlled, controls should be in place to minimise exposure and suitable personal protective equipment provided. Workers should receive adequate information, training and supervision.

Use the HSE’s welding guidance and resources to prepare for inspection.
