2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : high exposure to the commodities, inhalation or skin absorption, can cause weakness, blurred vision, ataxia, tremor, epileptic convulsion. Furthermore, the goods can cause metahemoglobin affect blood oxygen-carrying capacity, headache, dizziness, nausea, cyanosis. Eye contact and to stimulate serious burns. Right skin irritation.
chronic effects : This dust or liquid on the skin and lungs are sensitized, skin prickle, rashes and asthma.

two, toxicology information and environmental behavior

toxicity : Micro is a drug category.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industrial Press

5. Environmental standards :
former Soviet air workshop harmful substances 5mg/m3 maximum allowable concentration (piperazine adipate salt)

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leakage polluted area, located around the warning signs, the proposed emergency personnel wearing gas masks, chemical protective clothing to wear. Do not spill direct contact with the clean-shovel collection in a dry Clean covered containers, transported to the waste disposal sites. We could also use a lot of water washing, Add Water dilution of the wastewater system. If large spills, recycling or collection of sound waste treatment.

two protective measures

respiratory protection : general need special protection. If necessary, wear protective masks.
eye protection : to use safety masks.
protective clothing : wearing overalls (anti-corrosion material).
hand protection : Wear rubber gloves.
other : work, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : the pollution off clothing, immediately wash with water for at least 15 minutes. Medical treatment.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: patients to fully clear when the mouthwash, drinking water and medical treatment.

fire fighting methods : carbon dioxide, sand, foam, dry powder.
