EEF guide to safe working with metalworking fluids

Metalworking fluids (MWF) are essential to many machining processes. However, they can also cause ill health, affecting both the respiratory system and the skin. Effective control of MWF is therefore vital to prevent ill health and to comply with the law.

This guidance is relevant to any business that uses water-based metalworking fluids (also known as suds, coolants, slurry or soap), including wash fluids. Anyone working with metalworking fluids, or close to where they are being used, may be at risk of exposure and therefore of potentially harmful effects.

All users of metalworking fluids need to be especially aware of the risks of respiratory disease which may arise from exposure to mist, as well as the risk of dermatitis from direct contact with the skin.
