Metalworking fluids guidance

The Health and Safety Executive (HSE) has announced it is developing guidance on reducing the health risks to workers exposed to metalworking fluids, following a study of 31 engineering companies which the HSE said gave 'cause for concern'. However, despite the evidence that large numbers of workers are being exposed to unacceptable risks, the guidance will not be available for about 18 months.

The HSE study, carried out in conjunction with the Health and Safety Laboratory, measured workers' exposure to mineral oil and water-mix metalworking fluid mix and looked at control measures.

It found that many of the companies had poor control of fluid strength, poor sump replenishment methods and poor control of contamination. According to Martin Stear of the HSE's Occupational Hygiene Unit, failing to manage sump fluid conditions 'increases the risk of ill health among operators'.

Around 200 cases of contact dermatitis associated with metalworking fluids are reported every year, and there is an association between exposure to these fluids and respiratory effects, including asthma and bronchitis.

The guidance will develop new standards and describe good practice methods for controlling exposure to mist and managing sump fluids.

Copies of the study, Metal working fluids (MWFs) - exposure assessment document, can be ordered from HSE Books (see box) or from bookshops, price £7.50.
