Safety Precautions L 1 .^—y^
Safety Precautions (continued)
Used Engine Oil
Prolonged and repeated contart with mineral oil will result in the removal of natural fats from the
skin,
leading to
dryness, irritation and dermatitis. In addition, used engineoii contains potentially harmful contaminants which may
cause skin cancer. Adequate means of skin protection and washing facilities should be provided.
Health protection precautions:

1.
Avoid prolonged and repeated contact with oils, particularly used engine oil.

2.
Wear protective clothing, including impervious gloves where practicable.
3. Do not put oily rags in pockets.

4.
Avoid contaminating clothes with oil.
5. Overalls must be cleaned regularly. Discard unwashable clothes and oil impregnated footwear.
6. First aid treatment should be obtained immediately for open cuts or wounds.
7. Use barrier creams, apply before each work period to help the removal of oil from the
skin.

8. Wash with soap and water to ensure all oil is removed. Preparations containing lanolin replace the natural
skin oils which have been removed.
9. Do not use petrol, kerosene, diesel
fuel,
gas oil, thinners or solvents for washing
skin.

10.
If skin disorders develop, obtain medical advice.

11.
Where practicable, degrease components prior to handling.

12.
Where there is a risk of eye contact, eye protection should be worn, in addition, an eyewash facility should
be provided.
Environmental Protection
It is illegal to pour used oil on the ground, down sewers or drains, or into water courses. The burning of used engine
oil in small space heaters or boilers is not recommended unless emission control equipment is
fitted;
in case of doubt,
contact the Local Authority for advice on disposal facilities.
