Exposure to metalworking fluids (MWF) can cause harm to lungs and skin, while breathing in the mist generated by machining can lead to lung diseases.
Our series of 4 short videos aims to help you control worker exposure to MWF mist when Computer numerical control (CNC) machining. In addition, they show how you can use monitoring methods to assess control of MWF mist and check local exhaust ventilation (LEV) is working effectively.
The videos cover:
LEV helps control exposure to gas, vapour, dust, fume and mist in workplace air by extracting the clouds of contaminant at source before people breathe them in.
‘Commissioning’ is proving that the LEV system is capable of providing adequate control. As an employer, you should commission your LEV system to make sure it adequately protects people from breathing in harmful substances.
Under the Control of Substances Hazardous to Health Regulations, 2002 (COSHH) dutyholders must adequately control exposure to substances in the workplace that cause ill-health.
In Great Britain, occupational lung disease accounts for around 12,000 annual deaths, estimated to be linked to past exposures at work. A crucial part of our 10-year strategy 'The HSE Strategy - protecting people and places' is to reduce work-related ill-health, with a priority of tackling occupational lung disease.
