transparent colorless liquid smoke, the irritating odor; boiling point of 163.5 ° C; -87.3 ° C melting point; solubility : soluble in water; density : relative density (water = 1) 1.74; Stability : stability; Adversity risk Marker 20 (corrosive acid); the main purposes : for the manufacture of drugs used in organic synthesis and

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : the eyes, skin, and respiratory mucosa have a strong stimulating effect. Inhaling, ingestion or absorption through the skin after severe potentially lethal. Inhalation may throat, bronchial spasms, edema, inflammation, chemical pneumonia, pulmonary edema and death. Poisoning performance burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

two, toxicology information and environmental behavior

hazardous characteristics : Lu home air smoke, even heating, the irritating and corrosive.
combustion (decomposition) products : hydrogen fluoride and sulfur oxides.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
reference fluoride analysis

5. Environmental standards :
reference fluoride standards

6. Emergency treatment and disposal methods :
a leakage contingency

leak contaminated areas evacuated personnel to a safe area, not to prohibit access to the contaminated area, the proposed emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. A reasonable ventilation, not direct contact with the spill, rendering leakage and combustible materials (wood, paper, oil, etc.) contacts to ensure the safety of plugging. Water fog slowed volatile (or spread), but not to spill or leak water directly point. Use sand, vermiculite or other inert materials to absorb and then collect and transport the waste to disposal sites. If large spills, not the best treatment, the technical staff under the guidance of removals.

two protective measures

respiratory protection : its possible exposure to vapor or smoke, wearing gas masks or gas-helmet. Emergency rescue or escape, it is recommended to wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing overalls (anti-corrosion material).
hand protection : Wear rubber gloves.
other : work, take a shower. Separate storage of toxic pollution by the clothes, washed reuse. To maintain good health habits.

three, and emergency measures

contact with the skin : the pollution off clothing, immediately wash with water for at least 15 minutes. If it burns, medical care treatment.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. Difficult to breathe oxygen. Give 2-4% sodium bicarbonate solution aerosol inhalation. Medical treatment. Fresh into
: coverage to persons or egg white blues. Immediate medical treatment.

fire fighting methods : carbon dioxide, sand. Ban water.
