Hazardous characteristics: its vapor and air can form explosive mixtures case of fire, heat burn extremely flammable explosion. Violent reaction in contact with the oxidant. Heat generated by the decomposition of toxic chloride gas. Velocity too fast, easy and accumulation of static electricity. Its vapor is heavier than air, will spread to the lower Department of considerable local, fire source will fire back.
In case of high fever, increased pressure within containers, cracking and the risk of explosion. Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene. Fire fighting methods: firefighters are required to wear gas masks, body wear firefighting suits, the wind on fire. As far as possible to move containers from the scene empty Department. Water cooling containers to keep the fire until the end of fire. At the scene container if discoloration or to produce sound from the pressure relief safety devices must evacuate immediately. Extinguishing Media: water spray, foam, powder, CO2, sand.
Stability and reactivity:
Hazardous Polymerization: No aggregation
Conditions to be avoided: Light
Incompatibility: Strong oxidant, acids, bases, aluminum.
Closed operation, strengthening ventilation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators (half-mask), wearing chemical protective safety glasses, wear anti-static overalls, wearing rubber gloves. Away from fire, heat, workplace smoking. Use explosion-proof ventilation systems and
equipment. Prevent vapor leakage into the workplace air. Avoid contact with the oxidant, acids, alkalis. Filling should control the flow rate, and a grounding device to prevent electrostatic accumulation. When moving to light light unloading, prevent damage to packaging and containers. Equipped with the appropriate variety and quantity of fire equipment and emergency equipment leakage. Empty containers may remain
Store in a cool, ventilated warehouse. Away from fire, heat source. Storage temperature should not exceed 30 ℃. Should be stored separately and oxidant, acids, bases, etc., avoid mixing reservoir. Explosion-proof lighting, ventilation facilities. Prohibit the use of mechanical equipment and tools easy to produce sparks. Storage areas should be equipped with spill response equipment and materials suitable host.
Transport vehicles should be equipped with the appropriate variety and quantity of fire equipment and emergency equipment leakage during transport. The best summer morning and evening transportation. When used in transport groove (tank) cars should be grounded chain, tank can be installed to reduce the partition hole static electricity shocks. It is strictly prohibited and oxidant, acids, bases, food chemicals mixed mixed operation. Transit should be anti-exposure, rain, high temperature. Stopovers should be away from fire, heat, hot zone. Shipment of the goods vehicle exhaust pipe must be equipped with fire retardant devices, prohibit the use of easy to produce sparks of mechanical handling equipment and tools. According to the provisions road transport routes, not in residential areas and densely populated areas. Railway transportation to prohibit humping. Forbidden to use wooden, cement and bulk transport.
Skin contact: Remove contaminated clothing, mobile water rinse. Eye contact: Did eyelid, mobile water or saline rinse. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: drink enough water, induce vomiting. Medical treatment.
ACCIDENTAL RELEASE AND DISPOSAL:
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 positive pressure self-contained breathing apparatus, wear anti-static overalls. Cut off the source of leakage as possible. Prevent entry into sewers, flood discharge trench so restrictive space. A small leak: sand, vermiculite or other inert materials to absorb. You can also use non-flammable dispersant emulsions made of latex, wash, lotion diluted into the wastewater system. Large leak: to build a causeway or trenching asylum. With the transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites. Disposal: Disposal by incineration. Mixed with the fuel, and then burned. Incinerators emit hydrogen halide removed by acid scrubber.
Engineering controls: the production process confined to enhance ventilation. Provide safety shower and eye care equipment.
Respiratory protection: concentration in air overweight, they should wear protective masks Direct (half-mask). Emergency rescue or evacuation, it is recommended to wear air respirators
Eye protection: Wear protective chemical safety glasses
Physical protection: antistatic wear uniforms
Hand protection: Wear rubber gloves
Maximum acceptable concentration MAC (mg / m3): the former Soviet Union 10
Other protection: No smoking, eating and drinking. Workers completed, take a bath. Separate storage of toxic pollution by the clothes, washed standby. Pay attention to personal hygiene.
