transparent colorless liquid; 0.67kPa vapor pressure (20 ° C); the boiling point 130 ° C (48%); solubility : Compatibility with water, immiscible in alcohol; density : relative density (water = 1) 1.84 (48%); phase right density (Air = 1) 3.0; Stability : stability; risk Marker 20 (corrosive acid); the main purposes : Pb-Sn electroplating for conductive fluid, is also used as a catalyst, metal surfactant

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, ingestion or absorption through the skin is hazardous to health. Right eye, skin, and respiratory mucosa have a strong stimulating effect. Inhalation can result 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 : H foam immediately encountered combustion. Thermal decomposition of the release of toxic fluoride gas. With strong corrosive.
combustion (decomposition) products : hydrogen fluoride, boron oxide.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
assay (EPA Method 340.1,340.3) from the other
Progeny spectrometry (EPA Method 200.7)

5. Environmental standards :
American plant health standards 2.5mg/m3 [F]

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. Do not direct contact with leakage, in ensuring the safety of plugging. Use sand or other absorbent non-flammable mixture absorption, then collect and transport the waste to disposal sites. We could also use a lot of water washing, Add Water dilution of the 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 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, by acid burns 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. Stop breathing, artificial resuscitation immediately. Medical treatment. Fresh into
: coverage to persons or egg white blues. Immediate medical treatment.

fire fighting methods : carbon dioxide, sand.
