Basic properties and hazards
Basic properties	Non-caking crystals orange-red color. Non-volatile, water-soluble. Strong oxidant. Pollute the water.
Explosion and fire	Non-Flammable. Fire-and explosion-proof. When heated, decomposes to oxygen, contributing to potential combustion and rapid development of fire.
The risk to humans	Hexavalent chromium as aerosol or dust entering the body can cause severe poisoning. Prolonged exposure of hexavalent chromium compounds have a general toxic effect, causing respiratory diseases, gastrointestinal tract and skin issues. Hexavalent chromium compounds are irritating to the skin and mucous membranes of the eyes and nose. Hexavalent chromium leads to the formation of difficult to heal ulcers. Chemical burn. In case of fire and explosions can lead to burns and injuries.
Individual protection means	Insulating protective clothing FIR 5 complete with an insulating mask IP-4M. In case of fire — fire resistant suit, complete with self-rescuers SPI-20. At low concentrations in the air (with an increase in MPC 100 times) — overalls, industrial gas mask. Oil-resistant gloves, shoes. Respirator type SB-1 "petal" and Y-2K, goggles, clothing, footwear, hand protection.
