Get in a ditch and lay face down protecting your head with your hands.
Yes so long as you stay in it.
It isn't. Although the eye of a tornado is relatively calm, to get to it you have to go through the core winds of the tornado. It would be impossible to stay in the eye for very long.
You can go in a place without glass like windows
Storm spotters can help tell exactly were a tornado is and where it is going, so people in the path can be warned and get to safety.
A "fire tornado" is not a true tornado but a whirlwind spawned by an intense fire. If such a fire is approaching the area where you live you should evacuate immediately.
You would want to go to an under ground celer where the tornado can't reach.
Stay indoors, listen to the radio, take in loose objects that are outside, etc. But remember that even in a tornado watch, the odds that you actually get hit by a tornado are very low.
Head to the lowest floor of the apartment building, preferably a basement if possible. Stay away from windows.
No. It is not safe to be outdoors in a tornado, and outdoor elevators are often made largely of glass, which is dangerous to be near during a tornado.
They are very well practiced in how to stay safe in a tornado and known where to go when a tornado threatens. Schools in such areas hold regular tornado drills, just like other schools hold fire drills.
The makers on I-Doser say it is 100% safe but just to stay on the safe side I would not go for the drug ones :)
You should probably stay at least a quarter mile away from any tornado. This keeps you safe from debris and can give you some time to move if the tornado changes direction. Note, however, that you cannot judge the intensity of a tornado based on its appearance. It is a common misconception that a narrow tornado will be weak, when in fact it can be of any intensity. Even an F5 tornado can be skinny.
