Exposure controls: 
Appropriate engineering controls:   Safety shower and eye bath. Use only in a chemical fume hood. 
Individual protection measures, such as 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). 
Hand protection:   Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
(w ithout 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.
