2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin may cause death. Steam or smoke ocular mucosa, upper respiratory tract and skin irritation. To enter the body can lead to the formation of high methemoglobinemia. High concentrations can cause hair purple, symptoms sustainable 2-4 hours or more.

hazardous characteristics : case of fire, combustible high fever. With strong oxidant may react. Heat released by the decomposition of toxic gases.
combustion (decomposition) products : carbon monoxide, carbon dioxide, nitrogen oxides, hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
gas chromatography, liquid chromatography

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

leak contaminated areas evacuated staff to safety, not to prohibit access to the contaminated area, cut off the source of fire. Recommended emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. Do not direct contact with leakage, in ensuring the safety of plugging. Spray-water, reduce evaporation. Use sand or other absorbent non-flammable mixture absorption, then collect and transport the waste to disposal sites. Also a large number of irrigation water, diluted Add Water Wastewater System. If large spills, using a causeway asylum, and then to collect, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : its possible exposure to vapor, wearing gas masks. Emergency rescue or escape, wear positive pressure self-contained breathing apparatus.
eye protection : Wear protective safety glasses.
protective clothing : wearing tight sleeve dress, length boots.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Timely changed or washed overalls. Work was not drinking, bathing with warm water. Monitoring toxic. For pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : the immediate pollution of clothing off with soap and water thoroughly washed. Attention to hands, feet and other parts of the nail.
eye contact : immediately filed eyelid, with a large number of mobile or saline irrigation water.
Inhalation : rapidly from the scene to fresh air. Difficult to breathe oxygen. Breathing stopped immediately when respirators. Medical treatment. Fresh into
: coverage to persons mouthwash, water, activated carbon oral after gastric lavage, or give to catharsis. Medical treatment.

fire fighting methods : water mist, foam, carbon dioxide, dry, sandy soil.
