Engineering Controls: Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the  end of workday. 

Eye/Face Protection: Tightly fitting safety goggles. Faceshield (8-inch minimum). 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.  

The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from  it.  

Full contact –  

Material: Nitrile rubber. Minimum layer thickness: 0,4 mm 

Break through time: 480 min. Material tested: Camatril® 

Splash contact –  

Material: Nitrile rubber. Minimum layer thickness: 0,11 mm 

Break through time: 120 min. Material tested: Dermatril®  

Data source: KCL GmbH, D-36124. Test method: EN374  

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 respirator with multi purpose combination type OV/AG (US) or type ABEK (EU EN 14387) 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).
