colorless or slightly yellow liquid smoke, pick up the sourness; 30.66kPa vapor pressure (21 ° C); melting point -114.8 ° C / net; boiling point of 108.6 ° C / 20%; solubility : Compatibility with water, soluble in lye; density : relative density (water = 1) 1.20 ; the relative density (Air = 1) 1.26; Stability : stability; risk Marker 20 (corrosive acid); the main purposes : the inorganic chemicals, widely used in dyes, medicine, food, printing and dyeing, leather, and metallurgical industries

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : contact its vapor or smoke, conjunctivitis caused eye, nose and oral mucosa, burning sensation, epistaxis, gum bleeding, bronchitis; To stimulate the skin dermatitis, chronic bronchitis and other diseases. Coverage hydrochloric acid poisoning can cause gastrointestinal burns, ulcers, gastric perforation may have, such as peritonitis.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀900mg/kg (rabbit oral); LC₅₀3124ppm, 1 hour (rat inhalation)
hazardous characteristics : Can with some active metal powder reaction and emit hydrogen. Cyanide case can produce highly toxic hydrogen cyanide gas. Alkali occurrence with a response, and release a lot of heat. With corrosion.
combustion (decomposition) products : hydrogen chloride.

3. Emergency Monitoring Methods :
gas detector tube

4. Laboratory monitoring methods :
mercuricthiocyanate colorimetry "operating environment for air toxic substances detection methods," Chen editor

5. Environmental standards :
China (TJ36-79) Workshop harmful substances in the air that the maximum allowable concentration 15mg/m3

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 masks, wearing chemical protective clothing. Direct contacts will not leak, a ban on direct to the water leakage. More Do not allow water to enter the packaging containers. Use sand, dry lime or soda ash mixture, 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 : Immediately wash with water for at least 15 minutes. Or 2% sodium bicarbonate solution rinse. If it burns, medical care treatment.
eye contact : immediately filed eyelid, mobile water rinse for 10 minutes or 2% sodium bicarbonate solution rinse.
Inhalation : rapidly from the scene to fresh air. Difficult to breathe oxygen. Give 2-4% sodium bicarbonate solution aerosol inhalation. Medical treatment. Fresh into
: coverage immediately mouthwash to milk, egg white, vegetable oil, such as oral, not the symptoms. Immediate medical treatment.

fire fighting methods : mist of water, sand.
