to pure white crystals, black kids impure goods, with special smell; vapor pressure; melting point 1300 ° C; solubility : water-soluble; density : relative density (water = 1) 1.08; Stability : stability; risk Marker 10 (case of wet flammable substances); the main purpose for the fertilizer, and for the manufacture of nitrogen and steel quenching

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : dust inhalation of the goods can cause acute poisoning. Poisoning performance for the face, neck and skin redness thoracodorsal above, eyes, throat and palate mucosal redness, chills, etc..

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leakage polluted area, located around the warning signs, cut off the source of fire. Recommended emergency personnel wearing gas masks, chemical protective clothing to wear. Direct contacts will not leak, a ban on direct to spill water, not to allow water to enter the packaging containers. Avoid dust and clean the shovel collection in a dry Clean covered containers, transferred to a safe place. If large spills, using plastic sheeting, canvas cover, with the technology sector linkages, and to determine methods to remove.

two protective measures

respiratory protection : Workers should wear dust masks. When necessary recommendations to wear self-contained breathing apparatus.
eye protection : Wear protective safety glasses.
physical protection : wear overalls.
hand protection : Wear protective gloves.
other : no smoking scene work. For pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : contaminated clothing off immediately mobile water thoroughly washed. If it burns, medical care treatment.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes.
INHALED : from the scene to fresh air. To keep warm, when necessary, respirators. Medical treatment. Fresh into
: mouthwash coverage immediately, a large number of warm water to drink, the symptoms and to seek medical treatment.

fire fighting methods : dry, sandy soil. Ban water. Prohibit the use of foam.
