Now we are always hearing about road accidents，and when we’re in the car, we try to drive carefully, but how many of us take the same degree of care in our homes? Any large hospital will tell you the number of accidents that happen in the home is almost the same as those on the road. I don’t pretend to be an expert, but I've thought a lot about how and why these accidents happen and what we do to prevent them.

One of the commonest and most dangerous causes of home accidents is wrong and careless use of electrical equipment.People will continue to use a loose plug(插头)or pull out a plug without first turning off the power. Although there are warnings, one will carry an electric heater into the bathroom when he is going to have a bath. Sometimes one forgets to cut off the power before mending a lamp or something else. All this will cause accidents. So the rule about anything that works by electricity is: Switch off before you touch anything and don’t pretend you know when you actually don’t. If you’ve got children in the house, it’s always best to keep medicines of any kind out of their reach. Or, they may be taken for candies or new kind of drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy. Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can easily be knocked over. And don’t forget to keep the children away from fire. Smoking, too, may cause fire. So you’d better give it up. Safety first may mean more time and care, but it may save you a bit of trouble.
