Appropriate engineering controls 
Individual protection measures, such as personal protective equipment
Eye/face protection - Avoid eye contact. Wear safety glasses with side shields (or goggles).
Skin protection
Hand protection - Wear protective gloves. Suitable gloves can be recommended by the glove supplier.
Other - Wear suitable protective clothing.
