2. The impact on the environment
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : This is a strong irritant. High concentrations of mucosal serious damage, upper respiratory tract, eyes and skin. Contact can cause a burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

two, toxicology information and environmental behavior

toxicity : Production occasions broader application, but there is no such material damage caused by the report.
acute toxicity : LD₅₀400mg/kg (rat oral); > 10ml/kg (by the skin of guinea pigs)
subacute and chronic toxicity : inhalation 0.76mg / L × months, a weak, nausea, headache, mild anemia, leukopenia.

hazardous characteristics : case of fire, heat or contact with oxidants, combustion caused a risk of explosion. Heating decomposition flammable, toxic gases. "
combustion (decomposition) products : carbon monoxide, carbon dioxide.

6 environmental standards. Emergency treatment and disposal methods
a leakage contingency

rapid withdrawal from air leakage personnel to a safe area, and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators to wear protective clothing. As far as possible, cut off the source of leakage, prevent access to sewers, flood discharge trench so restrictive space. A small leak : sand or other materials Unburning adsorption or absorption. We could also use non-flammable dispersant made of latex, wash, lotion diluted Add to the wastewater system. Large leak : to build a causeway or trenching asylum. Foam coverage, lower vapor disasters. With the transfer pump to tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : its possible exposure to vapor, wear self-priming filtered gas masks (full cover).
eye protection : Respiratory Protection has been protective.
physical protection : gas-penetrating protective clothing.
hand protection : Wear gloves against chemicals.
other : work site prohibit smoking, eating and drinking. Pay special attention to the eyes and respiratory protection. Work to complete, thorough cleansing. Separate storage of toxic pollution were the clothes. Washed standby. To maintain good health habits.

three, and emergency measures

contact with the skin : immediately stripped of contaminated clothing, with a large number of mobile wash, at least 15 minutes. Medical treatment.
eye contact : immediately filed eyelid, with a large number of mobile water or saline thoroughly washed at least 15 minutes. 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
: oral intake of water were found to blues or egg white. Medical treatment.

fire fighting methods : Anti-insoluble foam, powder, CO2, sand.
