Metalworking fluids: new quiz, webinar and guidance

Issued: 11 January 2024

HSE is inspecting manufacturing businesses that use metalworking fluids in their machining processes until March.

Their Ebulletin contains facts, resources and guidance to help you make sure you are adequately protecting workers.

Quiz – test your knowledge

Exposure to metalworking fluids can cause harm to lungs and skin.

Work-related lung diseases have a devastating impact on workers’ lives, but when effective controls are in place, occupational lung diseases are preventable. Are you confident on how to protect your workers?

Webinar – managing metalworking fluid hazards

This short webinar provides information that will help you manage the health hazards from metalworking fluids.  

 It includes a case study of an HSE investigation, the control measures required to protect the health of workers and a summary of required fluid quality checks:

Three things to get right

Here’s a reminder of the main reasons that businesses fail to demonstrate compliance:

Local exhaust ventilation (LEV) 

LEV should be fitted to CNC machines where operators are exposed to metalworking fluid mist. It is the key control measure to reduce inhalation exposure.

For more information, download HSE’s guidance sheet COSHH MW1: CNC machining (.pdf).

Maintaining fluid quality 

Water-mix metalworking fluid deteriorates over time and can become contaminated with harmful bacteria and other contaminants. Monitoring and maintaining fluid quality is key to controlling risk.

For more information, download HSE’s guidance sheet COSHH MW5: Managing fluid quality (.pdf). 

Health surveillance 

Health surveillance is a scheme of repeated health checks which are used to identify ill health caused by work as early as possible. Where there is exposure to fluid or mist, it is a legal requirement to carry out health surveillance even when preventative controls, such as fluid quality checks and LEV, are in place.
