Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Full contact: Material: Nitrile rubber, Minimum layer thickness: 0,11 mm, Break through time: 480 min, Material tested: KCL 741 Dermatril® L. Splash contact: Material: Nitrile rubber, Minimum layer thickness: 0,11 mm, Break through time: 480 min, Material tested: KCL 741 Dermatril® L. This recommendation applies only to the product stated in the safety data sheet, supplied by us and for the designated use. When dissolving in or mixing with other substances and under conditions deviating from those stated in EN 16523-1 please contact the supplier of CE-approved gloves (e.g. KCL GmbH, D-36124 Eichenzell, Internet: www.kcl.de).
Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Safety glasses
required when dusts 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. Recommended Filter type: Filter type P2. 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.
