Metalworking fluids...a series of oils and other liquids used to cool and lubricate metalwork when being machined. Metalworking fluids are sometimes referred to as "Straight Oil" or "neat" oils. All metalworking fluids classes may contain additives such as stabilizers, biocides, dispersants, dyes, and odorants. When metalworking fluids are used there are a couple very serious concerns. There is a potential for oils to be heated high enough where the cutting tool works on metal workpieces to form polynuclear hydrocarbons. Also, it's presence of contaminants can encourage the growth of bacteria and fungi.

There are many metalworking fluid companies that are very aware of the dangers of these fluids. Extreme caution needs to be taken when utilizing these products. These products are used by hundreds of thousands of workers safely. Problems can occur due to improper hygiene or when the products are not maintained properly. Major health concerns of that can persist are skin irritation, allergic contact dermatitis, irritation of the eyes, nose and throat, and, occasionally, breathing difficulties such as bronchitis and asthma. Hypersensitivity pneumonitis from improperly managed fluids has been contracted in rare cases. This is an allergic type reaction in the lungs that is thought to be contracted due exposure to certain microbial products. Hypersensitivity pneumonitis symptoms include fever, chills, and shortness of breath and a deep cough.

Metalworking fluids can be very hazardous, but like so many products, prevention and simple care while using will go a long way in neutralizing its possible negative effects and allow you to enjoy their overall benefits.
