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 potentially

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 decreasing components, where
practicable, before handling them.
Other precautions:
D Avoid prolonged and repeated contact with oils,

particularly used engine oils.

D Wear protective clothing, including impervious

gloves where practicable.

D Avoid contaminating clothes, particularly

underpants, with oil.

D Do not put oily rags in pockets, the use of

overalls without pockets will avoid this.

D Do not wear heavily soiled clothing and

oil-impregnated foot-wear. Overalls must be
cleaned regularly and kept separate from
personal clothing.

belt.
Furthermore, the oil level sensor is located in the
oil pan, and a system is equipped whereby an
indicator gives a warning when the oil level drops.

harmful contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities must be provided.

D Where 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.

D Obtain First Aid treatment immediately for open

cuts and wounds.

D Wash 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.

D Do not use petrol, kerosine, diesel fuel, gas

oil, thinners or solvents for cleaning skin.

D Use barrier creams, applying them before each

work period, to help the removal of oil from
the skin after work.

D If skin disorders develop, obtain medical advice

without delay.
