NCIt definition : Any fluid that is used for lubrication and cooling during metalworking and machining
processes. They may be made from petroleum distillates, animal fats, plant oils, water,
or other ingredients. Toxicity or irritation can result from contact with cutting
fluids. The hazard can be the result of the fluid itself, the metal particles that
are borne in the fluid, the bacterial or fungal contaminants that tend to grow in
the fluid over time, the biocides that are added to inhibit those life forms, or the
corrosion inhibitors that are added to protect the machine and tooling.;
