Risks present when lubricating
If risk of splashing is present, make sure to wear protective eyewear with side guards.
When lubricating protect eyes and skin against contact with the substance. Therefore use
adequate protective wear with long sleeves and protective footwear. Also use protective gloves.
In case of a contact with skin, immediately wash the infected area with plenty of water with
soap.
Do not allow the product to contaminate water outlets, water courses and soils.
In case of an unintentional release to the environment plug the leak, limit the spillage, and then
collect the oil with non-flammable absorbent material (e.g. sand).
The product is flammable. In case of fire, use adequate fire-extinguishing means (e.g. foam,
water mist, extinguishing powders). Do not use water jets.
Disposal of the used product must be made according to official regulations. Improper disposal
of the used oil poses danger to the environment.
