ENGINE OILS
Health Warning
Prolonged and repeated contact with mineral oil
will result in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis.
In addition, used engine oil contains potentiallyharmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.
Recommended Precautions
The most effective precaution is to adapt working
practices which prevent, as far as practicable, the
risk of skin contact with mineral oils, for example
by using enclosed systems for handling used engine
oil and by degreasing components, where
practicable, before handling them.
Other precautions:
DAvoid prolonged and repeated contact with oils,
particularly used engine oils.
DWear protective clothing, including impervious
gloves where practicable.
DAvoid contaminating clothes, particularly
underpants, with oil.
DDo not put oily rags in pockets, the use of
overalls without pockets will avoid this.
DDo not wear heavily soiled clothing and
oil - impregnated foot - wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.DWhere there is a risk of eye contact, eye
protection should be worn, for example,
chemical goggles or face shields; in addition
an eye wash facility should be provided.
DObtain First Aid treatment immediately for open
cuts and wounds.
DWash regularly with soap and water to ensure
all oil is removed, especially before meals (skin
cleansers and nail brushes will help). After
cleaning, the application of preparations
containing lanolin to replace the natural skin
oils is advised.
DDo not use petrol, kerosine, diesel fuel, gas
oil, thinners or solvents for cleaning skin.
DUse barrier creams, applying them before each
work period, to help the removal of oil from
the skin after work.
DIf skin disorders develop, obtain medical advice
without delay.
