Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Immediately change contaminated clothing. Apply preventive skin protection. Wash hands and face after working with substance.
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. Full contact: Material: Nitrile rubber, Minimum layer thickness: 0.4 mm, Break through time: 480 min, Material tested: Camatril® (KCL 730 / Aldrich Z677442, Size M). Splash contact: Material: Nitrile rubber, Minimum layer thickness: 0.11 mm, Break through time: 69 min, Material tested: Dermatril® (KCL 740 / Aldrich Z677272, Size M). Test method: EN374.
Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Tightly fitting safety goggles.
Recommended Filter type: Filter type ABEK. The entrepreneur has to ensure that maintenance, cleaning and testing of respiratory protective devices are carried out according to the instructions of the producer. These measures have to be properly documented. Required when vapours/aerosols are generated. Our recommendations on filtering respiratory protection are based on the following standards: DIN EN 143, DIN 14387 and other accompanying standards relating to the used respiratory protection system.
