EXPOSURE CONTROLS/PERSONAL PROTECTION8.1 Control parameters
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
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 gloves 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.
The selected protective gloves have to satisfy the specifications of Regulation (EU)
2016/425 and the standard EN 374 derived from it.
Material: Nitrile rubber
Minimum layer thickness: 0,11 mm
Break through time: 480 min
If used in solution, or mixed with other substances, and under conditions which
differ from EN 374, contact the supplier of the CE approved gloves. This
recommendation is advisory only and must be evaluated by an industrial hygienist
and safety officer familiar with the specific situation of anticipated use by our
customers. It should not be construed as offering an approval for any specific use
scenario.
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 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
Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
Discharge into the environment must be avoided.
