The HSE takes an ‘APC’ approach to risk management based on Avoidance (e.g. avoiding exposure through working practices), Protection (using correct personal protective equipment, or PPE)) and Checking (monitoring and reporting systems and health).
Choosing the right metalworking fluid To minimise the risk of exposure, using the ‘right’ metalworking fluid is a good starting point. Choice is largely dictated by the application, but it is important to identify the best product that combines safety, performance and economy. Metalworking fluids are developed with these principles in mind and their component make-up varies to suit the application. The components in a formulation may be critical to the application but can also be hazardous. Achieving the correct balance of effectiveness versus potential harm is always challenge.
It is important to consider the quality of the metalworking fluid during the full machining cycle. In the long term it may be safer and more economical to use a more expensive product which provides a longer fluid life and greater protection to the operator from exposure to harmful microorganisms.
The complex makeup of a metalworking fluid varies widely, and lubricant manufacturers are required to provide a CLP (classification, labeling and packaging) complaint safety data sheet which details its basic properties and gives information on hazardous components and exposure. It is important to stress that the hazard classification for soluble metalworking fluids relates to the concentrated product as supplied; when diluted, any hazard is significantly reduced.
Dangers associated with the mist generated by metalworking fluids are not always obvious. Even though some fluids are less hazardous than others, remember that there is no such thing as a healthy mist!
It is vital to maintain the concentration and optimum operating conditions for metalworking fluids within the limits recommended by the lubricant supplier. These are usually shown on a product data sheet. It is advisable to display a fluid monitoring chart which includes the recommended operating conditions on individual machines or nearby notice boards.

The Good Practice Guidance for the Safe Handling and Disposal of Metalworking Fluids was recently launched by UKLA’s Metalworking Fluid Product Stewardship Group in partnership with HSE. Q8Oils was a key member of the advisory panel of industry experts set up by the Group to compile the guide.
Q8Oils offers a wide range of high-quality metalworking fluids and cutting oils based on the latest technology, and can advise on the best option for your application. We can also offer advice through our QCare support service on how to comply with COSHH legislation and carry out fluid monitoring services, including on site visits.

system and are susceptible to contamination over time. This could be chemical contamination, such as tramp oil, or by microorganisms, in particular bacteria, fungi and yeast.
It may be obvious when a fluid is contaminated, for example a noticeable foul odour, but some changes are more subtle and difficult to detect. The only certain way to evaluate a fluid’s condition is through regular monitoring and testing, based on HSE guidelines. It is also vital to have an adequate filtration and local exhaust ventilation (LEV) extraction system in place and to carry out regular checks and maintenance, including a thorough inspection every 14 months by a qualified ventilation engineer.
