Metalworking inspections from the Health and Safety Executive (HSE) are set to have an increased focus on health surveillance. Exposure to metalworking fluids can cause harm to lungs and skin. Health surveillance aims to detect any symptoms of ill health caused by work as early as possible.
HSE will be inspecting manufacturing businesses that use metalworking fluids or ‘white water’ in their machining processes until March 2024. Not providing regular health surveillance is one of the common reasons that manufacturing companies fail to demonstrate compliance, particularly smaller companies.
What does the law require?
Health surveillance is a scheme of repeated health checks which are used to identify ill health that is caused as a result of work.
The law states that, 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 local exhaust ventilation (LEV), are in place.
Focus on Lung and Skin Conditions
For those who work with metalworking fluid, exposure through mist inhalation or direct contact can cause lung diseases and irritated skin (dermatitis).
HSE’s latest statistics (2022 to 2023) show:
- an estimated 12,000 people died from lung diseases linked to exposure to hazardous substances at work
- an estimated 19,000 new cases of breathing and lung problems thought to be caused or made worse by work
- the manufacturing industry has a substantially higher rate than average for occupational asthma
- metalworking machine operatives have much higher dermatitis rates than many of the major groupings of occupations
More about Control Measures
Work-related lung diseases have a devastating impact on workers’ lives but when effective controls are in place, occupational lung diseases are preventable.
The feedback from your health surveillance can also provide information on whether your control measures are protecting workers.
Two key control measures when working with metalworking fluids are:
- Local exhaust ventilation
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.

- 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 are key to controlling risk.
