Making sure your children know exactly what is required of them cuts down the chaos of the emergency situation and helps keep your family safe and secure. All children should know about important fire safety procedures. For example, tell your children to stay low to the ground in a smoky room, which keeps them from breathing smoke, as smoke always rises towards the ceiling. Also tell them that they can put a damp towel or a piece of clothing over their faces and breathe in through it to cut down the effects of breathing smoke even more. In addition, make sure your children know how to correctly stop, drop and roll when their clothes catch fire. Because it results in loss of oxygen, which puts out the flames. Also your children should know to touch door handles before opening the doors to see if they’re hot. If they are, it means there’s a fire in the next room, and they should leave the door closed and find another route out of the house. Make sure your children never play with lighters or matches. Usually, many children are attracted by lighters and matches and want to experiment with setting things on fire to see what happens. So hide lighters and matches in some place your children can’t reach. Do regular fire drills to act out and improve your evacuation（疏散）plan. Make sure everyone knows all the possible exits of the house they can use, and that all members of your family know your evacuation plan well enough so that they don’t have to waste time thinking if a fire starts. Quick, determined response to a fire will save your family members’ lives.
