SECTION 8: Exposure controls/personal protection
8.1. Control parameters8.2. Exposure controls

Protective and hygiene measures
Take off contaminated clothing. Wash hands before breaks and after work. When using do not eat or drink.
Eye/face protection
Wear eye protection/face protection.
Hand protection
When handling with chemical substances, protective gloves must be worn with the CE-label including the fourcontrol digits. The quality of the protective gloves resistant to chemicals must be chosen as a function of thespecific working place concentration and quantity of hazardous substances. For special purposes, it isrecommended to check the resistance to chemicals of the protective gloves mentioned above together with thesupplier of these gloves.
Skin protection
Wear suitable protective clothing.
Respiratory protection

In case of inadequate ventilation wear respiratory protection.
