Basic properties and hazards
Basic properties Monolithic mass, flakes, granules, from light brown to dark brown. It is soluble in water, in contact with acids liberates hydrogen sulfide — flammable explosive gas.
Nonvolatile. Corrosive to some metals.
Explosion and fire Not flammable.
The risk to humans Harmful by inhalation (cough, chest tightness, runny nose, watery eyes), skin contact (skin burn) and eyes (eyelid edema, conjunctiva redness, damages the iris). Chemical burns.
Individual protection means Insulating protective clothing FIR 5 complete with an insulating mask IP-4M or-arms protective suit L-1 and L-2, complete with industrial gas mask with a cartridge in the gloves of the variance of butyl rubber, shoes.
At low concentrations in the air (with an increase in MPC 100 times) — clothing, self-protective individual set-fed into the breathing zone of the purified air ROM cartridges, PZ-2, filter respirator "FORT-P", the universal respirator "Snowball-KU -M".
