the material to the environment may endanger the water bodies should be given special attention.

a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin is hazardous to health. Serious damage to mucous membrane, upper respiratory tract, eyes and skin. Inhalation can hose, bronchospasm, inflammation and edema, chemical pneumonia or pulmonary edema and death. Contacted after the burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

two, toxicology information and environmental behavior

hazardous characteristics : no special combustion characteristics of the explosion.
combustion (decomposition) products : hydrogen fluoride.

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 and gloves. Rinse with plenty of water, diluted Add Water Wastewater System. Leak large collection shipped to recycling or waste disposal sites disposal.

two protective measures

respiratory protection : Workers should wear protective masks.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective clothing polyethylene film.
hand protection : Wear protective gloves.
other : work site prohibit smoking, eating and drinking. After work, take a shower. Pay attention to personal hygiene. Implementation of pre-employment and periodic medical examinations.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, immediately with a large number of mobile water thoroughly washed at least 15 minutes. Medical treatment.
eye contact : immediately open from top to bottom eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Respiratory stop immediately mouth. Medical treatment. Fresh into
: to blues or egg white. Medical treatment.

fire fighting methods : Unburning. Sound can be used around the fire extinguishing media.

6 . 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 respirators-positive pressure self-sufficiency, wearing fire 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 : activated carbon or other inert materials to absorb. 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. Ex pump used to transfer 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 (half-mask). Emergency rescue or evacuation, wearing oxygen respirator.
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear latex gloves.
other : no smoking scene work. Work to complete, take a shower. Pay attention to personal hygiene.

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-extinguishing agent : carbon dioxide, dry, sandy soil. Ban water.
