Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
For full contact, use Viton gloves with a minimum layer thickness of 0.7 mm and a breakthrough time of 480 min (Material tested: Vitoject, KCL 890 / Aldrich Z677698). For splash contact, use Nitrile rubber gloves with a minimum layer thickness of 0.4 mm and a breakthrough time of 10 min (Material tested: Camatril, KCL 730 / Aldrich Z677442). When dissolving in or mixing with other substances and under conditions deviating from those stated in EN374, contact the supplier of CE-approved gloves.
Safety glasses. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Recommended Filter type: Filter A (acc. to DIN 3181) for vapours of organic compounds. 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.
Protective clothing.
