ENGINE OILS

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

.

Recommended Precautions

The most effective precaution is to adapt working 
practices which prevent, as far as practical, the risk 
of skin contact with mineral oils i.e. use enclosed 
systems for handling used engine oil and degrease 
components, where practical, before handling them.

.

Other precautions:

• Avoid prolonged and repeated contact with oil, 

particularly used engine oil.

• Wear protective clothing, including impervious 

gloves where practical.

• Avoid contaminating clothes with oil.

• Do not put oily rags in pockets.

• Do not wear heavily soiled clothing and 

oil-soaked foot-wear. Overalls must be cleaned 
regularly and kept separate from personal cloth-
ing.

• Where there is a risk of eye contact, eye protec-

tion should be worn i.e. chemical goggles or face 
shields. In addition, an eye wash facility should 
be provided.

• Obtain first aid treatment immediately for open 

cuts and wounds.

• Wash regularly with soap and water to ensure all 

oil is removed (skin cleansers and nail brushes 
will help). After cleaning, apply lotion, etc., con-
taining lanolin to replace natural skin oils is 
advised.

• Do not use gasoline, kerosene, diesel fuel, gas 

oil, thinners or solvents for cleaning skin.

• Apply barrier creams before each work period.

• If skin disorders develop, obtain medical advice 

immediately.

ENGINE OIL CHECK

M1121000900397
1. Pull out the oil dipstick slowly and check that the oil level is 

within the marks on the oil dipstick.

2. Check that the oil is not excessively dirty, that there is no 

coolant or gasoline mixed in, and that it has sufficient 
viscosity.

ENGINE OIL REPLACEMENT

M1121001000706
