If you are in a building get to a basement, crouch down, cover your head and try to make your self as small as possible..
If no basement is available got to a room in the center part of the lowest floor and stay away from windows. Closets and bathrooms offer good protection.
If you are in a car abandon it and seek a sturdy shelter. If no shelter is available lie down in a ditch.
u should be somwhere he ground so u can be safe
You should not be in a mobile home if there is a tornado coming. Mobile homes are very susceptible to tornado damage and should be abandoned for sturdier shelter during a tornado warning.
I'd be looking for safe shelter.
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.
There are saferooms, more often called storm shelters. These are reinforced or underground rooms that are designed to keep people safe during a tornado. Ideally, one should be able to withstand an EF4 and perhaps an EF5 tornado.
To some degree. You should only take cover in a ditch from a tornado as a last resort if no shelter is available.
cellar. or if it comes to it your bathtub cover yourself with a mattress
You should get to your basement or cellar, and if you don't have one, get in a bathtub with a mattress over you.
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.
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.
Nothing guarantees safety in a tornado and most habitable places on earth can and do get them. However, most of the time you will be safe if you can get to an underground shelter. That said tornadoes are very dangerous and you should always take the threat of one seriously.
Farmers should have a designated safe shelter for their livestock during a tornado, such as a sturdy barn or underground bunker. They should also ensure that their animals have identification tags and are securely fenced in to prevent them from wandering during a tornado. Additionally, farmers should have a plan in place to quickly evacuate their livestock to a safe location if necessary. Special precautions should be taken for tornado cows, such as ensuring they are securely tethered or housed in a sturdy structure that can withstand strong winds.
