Appropriate engineering controls:   Safety shower and eye bath. Use non-sparking tools. Mechanical exhaust required. 
Individual protection measures, such as personal protective equipment: 
Eye/face protection:   Chemical safety goggles. 
Hand protection:   Use chemical resistant gloves. Examples of preferred glove barrier materials include: Butyl rubber,
Neoprene, Nitrile/butadiene rubber, Polyethylene, Ethyl vinyl alcohol laminate, polyvinyl alcohol, Polyvinyl chloride. 
Body protection:   Not necessary under normal conditions of use. 
Respiratory protection:   Use respirators and components tested and approved under appropriate government
standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use
a full-face particle respirator type N100 (US) or type P3 (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.
