2010165438+1October 15 A fire broke out in a 28-story teacher apartment in Jiaodong Road, Shanghai, killing 58 people. The cause of the accident was that the workers violated the rules and ignited sparks during welding. (1) Polyurethane is an organic synthetic material, which is flammable, so the answer is: organic;

(2) The electric spark plays the role of igniting polyurethane, that is, providing its combustion temperature.

(3) Once a fire is found, it should be considered: keep a good attitude, use evacuation passages and safety exits to help yourself escape, cover your nose and mouth with a wet towel, and crawl to escape. Never jump off a tall building or take an ordinary elevator to escape quickly. Even if it doesn't burn, it may be killed. This way is absolutely not desirable. Therefore, cover your nose and mouth with a damp cloth as soon as possible and evacuate to a safe place.
