solution for its transparent colorless liquid smoke, irritating odor; vapor pressure; boiling point of 108.5 ° C; solubility : soluble in water; density : relative density (water = 1) 1.32 (about ); Stability : stability; risk Marker 20 (corrosive acid); the main purposes : Preparation Fluorosilicate and four fluorinated silicon materials, but also used metal plating, wood preservation, disinfection and other beer

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : direct contact with the skin, cause redness, burning sensation Locally, severe ulcers. The role of the body may hydrofluoric acid, but weaker.

two, toxicology information and environmental behavior

hazardous characteristics : heat decomposition emit toxic fluoride gas. With strong corrosive.
combustion (decomposition) products : hydrogen fluoride.

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. 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, 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. 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, dry powder, foam.
