8.1 Control parameters
Components with workplace control parameters
Contains no substances with occupational exposure limit values.
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: 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.
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 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. Use respirators and components tested and approved under appropriate government
standards such as NIOSH (US) or CEN (EU).
Control of environmental exposure
Do not let product enter drains.
