red rhombus crystallization deliquescence easy; boiling point decomposition; the temperature 55 ° C; solubility : dissolve in water, acid; density : the relative density (Water = 1) 1.87; Stability : stability; risk Marker 11 (oxidizer); the main purposes : pigments, catalysts and ceramics for industrial

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : ocular, respiratory and skin irritation. After inhaling the cause shortness of breath, coughing. Oral cause abdominal pain, vomiting.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀434mg/kg (rat oral); 400mg/kg · (rabbit oral)
reproductive toxicity : poisoning mice were injected subcutaneously with the lowest dose (TDL0) : 14 .6mg/kg (30 days, male), arising from testis, epididymis, vas deferens change.
cancer : IARC carcinogens comments : human carcinogen lack of evidence.

hazardous characteristics : inorganic oxidizer. The fire which will burn any long deadlock on the fire. With organic, reductant, combustibles such as sulfur, phosphorus or metal powders can be mixed to form an explosive mixture. At 74 ° C begin to decompose and emit toxic nitrogen oxides.
combustion (decomposition) products : nitrogen oxides.

3. Emergency Monitoring Methods :
water rapid colorimetric tube (Japan system, nitrate)

4. Laboratory monitoring methods : acid
phenol two spectrophotometry (GB7480-87, Water) (nitrate)
ion chromatography (GB13580.5-92, Water) (nitrate)

5. Environmental standards :
China (GB5749-85) drinking water standard 20 mg / L (nitrate, N dollars)
China (GB/T14848-93) groundwater quality standards (mg / L) Class I 2.0; Type II 5.0; Class III 20; class IV 30; category V 30 above (nitrate, N dollars)
China (GHZB1-1999), surface water quality standard ( mg / L) Class I 10; Class II 10; Class III 20; class IV 20; category V 25 (nitrate, N dollars)

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Recommended emergency personnel wearing self-contained breathing apparatus to wear uniforms for the general operations. Rendering leakage and reductant, organic material, combustible material or metal powder contacts. A small leak : clean shovel collection in a dry, clean, covered containers. Large Leak : recycling or collection shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : higher concentration in air, should wear self-priming filtered respirators. When necessary, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective clothing 52,400.
hand protection : Wear rubber gloves.
other : work to complete, take a shower. To maintain good health habits.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: warm water to drink enough, the symptoms. Medical treatment.

fire fighting methods : firefighters must wear a gas mask filter type (full cover), or isolated respirators, wearing fire protective body suits, upwind of the fire. Do not flow directly from radio to melt, to avoid serious fire or the flow causes intense boiling splash. Extinguishant : mist of water, sand.
