butadiene

As butadiene butadiene, is C4H6 formulas for the organic compound, an important chemical raw materials, can be used in the manufacture of synthetic rubber (styrenebutadiene rubber, butadiene rubber, butyl rubber, butyronitrile rubber). Risk category: invasion way: health hazard: this product has the anesthesia and stimulation. Acute poisoning: light person have headaches, dizziness, nausea, sore throat, tinnitus, muscle weakness, sleepiness and so on. The person that weigh appear drunken state, difficulty breathing, pulse rate, loss of consciousness and transferred after tics, sometimes also can have fidgeting, run around mental symptoms. After the break contact, rapid recovery. Headaches and sleepiness sometimes sustained over a period of time. The skin direct contact butadiene can happen burns or frostbite. Chronic influence: long-term exposure to certain concentration of butadiene can have headaches, dizziness, muscle weakness, insomnia, dream, memory loss, nausea, heart palpitations and other symptoms. I see dermatitis and multiple neuropathy. Environmental hazards: harm to the environment, the water, soil and air can cause pollution. Explosion danger: this product flammable, has excitant. Prevention measures: dangerous characteristics: flammable, mixed with air explosive mixture can be formed. Contact heat, Mars, flame or oxidant easy burning explosion. If encounter high fever, can happen polymerization, let out a lot of heat and cause containers rupture and explosion accident. Gases than air heavy, can in the lower spread to rather far away, in fire will burn on fire back. Harmful combustion products: carbon monoxide, carbon dioxide. Fire extinguishing method: cut off the air supply. If you can't cut off gas source, is not allowed to put out the flame of leakage place. Water spray cooling container, possible will be moved to the empty containers from the fire place. Agent: mist water, foam, carbon dioxide, dry powder.
