The fumes and mists generated during mechanical processing are complex mixtures of airborne substances composed mainly of mineral oils, polycyclic aromatic hydrocarbons, aldehydes, heterocyclic compounds of various kinds (PCB, N-nitrosamines, etc.), metals coming from tools and material being processed (Ni, Cr, Co, Pb, Fe, etc.). As for biological agents, anaerobic bacteria, especially sulphite-reducing bacteria, can produce hydrogen sulfide and other foul-smelling toxic gases. Water-based coolant fluids are also excellent nutrient sources for many bacteria and fungi.
The health risk deriving from exposure to cooling lubricating oils is linked to:
– To the refining processes to which the oil has been subjected.
– To additives that are added to the base oil.
– The manner in which it is used and the protective measures that are adopted.
The main risk factors deriving from exposure to coolant oils are attributable to skin contact with the fluid and the inhalation of mists, deriving from oil aerosol, and fumes, resulting from thermal degradation.
Dermatitis, acne, asthma, irritation of the upper airways and various types of cancer have been associated with exposure to coolant oils. The severity of the disease is related to various factors, such as the type of fluid, the degree of contamination, the duration and level of exposure.
Fumes and oily mists are emissions that are generated as a result of friction and heating of particular substances such as cooling lubricant oils used in many industrial processes, especially in the metalworking sector. Often the spread of pollutants within the work environment is related to both of these factors.
Oil mist
Oil mist consists of airborne oil droplets.The size of these varies from 1 to 10 μ m.La oil mist is normally formed in processes where coolant oil is used for chip removal and the most common and effective way to capture it is to purify polluted air as close as possible to the source.
Oil smoke
Oil smoke, like oil mist, consists of airborne droplets of oil. The difference is that these particles are smaller than oil mist particles and usually arrive in larger quantities. The size of oil mist particles varies from 0.1 to 1 µm. The threshold limit for the amount of oil smoke allowed in a workshop is normally the same as for oil mist
Dust
Dust formed during a variety of applications where dry materials are processed. For example, during welding, laser and plasma cutting,dry grinding, sanding or painting. Dust consists of airborne particles down to 100 microns, which is equivalent to one tenth of a millimetre.
Larger particles that are not airborne are also considered dust particles.
