Engineering controls
Facilities storing or utilising this material should be equipped with an eyewash facility and safety shower. Use adequate ventilation to keep airborne concentrations low. A local exhaust system which captures the contaminant at its source is recommended to prevent dispersion of the contaminant into the workroom air.
Personal protective equipment
Eye and face protection
Use chemical safety goggles. Contact lenses should not be worn when working with this material. Maintain eye wash fountain and quick?drench facilities in work area.
Skin protection
Wear protective gloves. 0.11mm thick nitrile.
Body protection
Wear a clean body?covering clothing.
Respiratory protection
For conditions of use where exposure to the dust is apparent, a dust/mist respirator may be worn. For emergencies, a self?contained breathing apparatus may be necessary.
