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.

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 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 
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the 
environment must be avoided.
