What safety precautions do you need to take so that you will be safe during a tornado?

The first safety precaution you need to take during a tornado is to have the weather channel on loud or have a weather radio so that you know when the storm is coming, how severe it is, and when it is ending. The second precaution is to hide in a room with no windows so that the tornadoes air pressure doesn't break the glass. Another precaution would be to put a mattress ontop of your body. You don't neccessarily have to put a mattress on your head, just anything that would protect you from falling objects or materials that the tornado may make. Also if you have a tornado shelter then you have an obvious answer to this question.

If you are in a car and you somehow figure out that a tornado is coming then you can take these basic precautions. First you pull over if you are in a rural area. Then you find a secluded area or a ditch that you can lay down in until it is over. Also if you can find cushiony materials where you are, or have some in your car bring them with you. Whatever material you find bring it with you and protect yourself. One of the biggest mistakes you can make is trying to beat the tornado in a car race. Some tornadoes can travel up to 100 mph.
If you are in the city during a tornado follow these safety procedures. Find a safe place (if possible) to park your car. Find the nearest biggest building in town. Also metallic structures are much more study than wooden structures. Go into a small room secluded with no windows. If others do not know of the tornadoes presence then tell them. Keep someone constantly monitoring the weather channel. Most importantly, be patient and wait until you know the storm has ended.
