2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health risks : cyanide and similar goods, cytochrome oxidase and other enzyme inhibition, and allowing the body oxygenated hemoglobin formation blocked, there were significant antihypertensive effect. Eye and skin irritation. If inhaled, swallowed or absorbed through the skin, can cause poisoning. Hypertensive patients with oral administration of the goods significantly reduce blood pressure. The materials in organic synthesis can azide acid gases escape, inhalation poisoning after vertigo and weak, blurring of vision, difficulty in breathing, fainting flu, lower blood pressure, such as bradycardia.

two, toxicology information and environmental behavior

toxicity : high toxicity category.
acute toxicity : LD₅₀27mg/kg (rat oral); 20mg/kg (rabbit percutaneous)
hazardous characteristics : heat, contact the fire, or by friction, vibration, the impact can be an explosion. The goods and acids have seen explosive azide acid. With the formation of salts of heavy metals and sensitive compounds.
combustion (decomposition) products : NO.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
ion chromatography (azide) "environmental monitoring," Zhou Chong-series
ion selective electrode (azide) "environmental monitoring," Zhou Chong-series
sodium azide Spectrophotometric Determination of [published in the British] / Terpinski E.A. / / Analyst (Lonkon) .- 1985,110 (11). from 1405 -1403, "Analytical Chemistry Digest" 1987.7.

5. Environmental standards :
American plant health standards 0.3mg/m3
China (GB4279-84) lead azide industrial water pollutant discharge standards of not more than 0.5 mg / L (azide. N dollars)

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators to wear protective clothing. Do not direct contact with leakage. A small leak : to avoid dust, carefully scan, bag placed transfer to a safe place. Large Leak : plastic sheeting, canvas cover and reduce dispersion. Then the collection, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to dust, must wear headgear electric powered air-purifying respirators and dust. Emergency rescue or evacuation, it is recommended to wear self-contained breathing apparatus.
eye protection : Respiratory Protection has been protective.
physical protection : Cruise-wear protective clothing 52,400.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, take a shower. Separate storage of toxic pollution by the clothes, washed standby. 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 and to seek medical treatment.

fire fighting methods : fire officers must wear body fire protective clothing. Because of the fire may occur Yung moved to the bursting of the firefighters in a blast of operating shelters. Extinguishant : mist of water, carbon dioxide, foam. Prohibit the use of sand gland.
