SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Control parameters
Components with workplace control parameters
Contains no substances with occupational exposure limit values.
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 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
Impervious clothing, 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 fullface
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.
