21.3 Safety regulations for the handling of cooling lubricant

1. Pay particular attention to leaked coolant as this can quickly cause people to slip and caused
accidents as a result.
2. Secure your coolant system in such a way that it cannot be switched on by children. Persons who
have not been trained may not operate the coolant system.
3. Ensure you have a clean workplace, dirty areas can quickly lead to accidents.
4. Never use the coolant system when processing magnesium alloys. In combination with water-
mixed coolants, this may result in flammable gas mixtures which may explode under certain
circumstances.
5. Avoid longer skin contact with the coolant.
6. Use skin protecting creams when handling coolants.
7. Regularly monitor the concentration of the water-mixed coolant.
