Section8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Control parameters 
Components with workplace control parameters 
Exposure controls 
Appropriate engineering controls 
Avoid contact with skin, eyes and clothing. Wash hands before breaks and immediately after handling 
the product. 
Personal protective equipment 
Eye/face protection 
Face shield and safety glasses Use equipment for eye protection tested and approved under 
appropriate government standards such as NIOSH (US) or EN 166(EU). 
Skin protection 
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique 
(without touching glove's outer surface) to avoid skin contact with this product. Dispose of 
contaminated gloves after use in accordance with applicable laws and good laboratory practices. 
Wash and dry hands. 
The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and 
the standard EN 374 derived from it. 
Body Protection 
Complete suit protecting against chemicals, The type of protective equipment must be selected 
according to the concentration and amount of the dangerous substance at the specific workplace. 
Respiratory protection 
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle 
respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering 
controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use 
respirators and components tested and approved under appropriate government standards such 
as NIOSH (US) or CEN (EU).
