What if there is a fire in your house? Would you know what to do? Here are several suggestions which might help you escape (逃生) from the fire.
Leaving the house through a door should be your first choice as an escape route. Windows on a higher floor may be a safe escape route if you could get help from another person.
If you can see smoke in the house, stay low to the ground as you go to the door. In a fire, smoke and poisonous air hurt more people. You’ll breathe less smoke if you stay close to the ground.
If fire or smoke is blocking (阻塞) an escape route, you do this, firefighters (消防队员) will have difficulty finding you. The sooner they find you, the sooner you can get out.
Meanwhile, keep heat and smoke from getting through the door by blocking the cracks (缝隙) around the door with blankets, or clothing. If there is a window, open it all the way and stand in front of it. If you can get a piece of clothing, cover your mouth to keep from breathing in the smoke. This works even better if you wet the cloth first.
If your clothed catch fire during a fire, don’t run! You had better stop, drop to the ground, and roll. This will cut off the air and put out the fire.
