Safe handling and disposal of metalworking fluids and what the law requires
It is essential to maintain the quality of metalworking fluids to prevent ill-health in machine workshops, as well as ensuring good fluid performance and comply with health and safety laws. Changes in appearance and odour are indications of microbial contamination in metalworking fluids and can cause operators to contract skin diseases such as dermatitis, as well as lung disease (occupational asthma and occupational hypersensitivity pneumonitis) if they are regularly exposed to or inhale the mists of the contaminated fluids.
Metalworking fluids deteriorate with use over time, due to tramp oil contamination, soluble metals, metal fines, and microorganisms (bacteria, yeast and fungi). Overuse of biocides to discourage microorganisms in metalworking fluids may also increase the possibility of health risks to operators.
The law requires that employers should carry out a suitable risk assessment for operators exposed to metalworking fluids. It should identify the measures required to ensure that exposure is either prevented or kept to a minimum.
In summary, this means
- Reducing skin contact with metalworking fluids.
- Reducing inhalation of metalworking fluids mist to levels “as low as reasonably practicable” (ALARP).
- Applying COSHH principles of good control practice such as control measures that are proportionate to the risk and are the most reliable in minimising the escape and spread of MWF mist.
