Components with workplace control parameters

8.2 Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at
the end of workday.
Personal protective equipment
Eye/face protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested andapproved 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.
Body Protection
Impervious clothing, flame retardant antistatic protective clothing. The type of protective equipment must
be selected according to the concentration and amount of the dangerous substance at the specificworkplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator withmultipurpose combination (US) or type AXBEK (EN 14387) respirator cartridges as a backup toengineering controls. If the respirator is the sole means of protection, use a full-face supplied airrespirator. Use respirators and components tested and approved under appropriate government
standards such as NIOSH (US) or CEN (EU).
