Protections in entering the hot zone

There are a lot of protections when you enter a hot zone. First you have to make sure that you have your protective suit on so that you can not breath the air of the hot zone. You have to make sure that your siut does not have a tear  because if you breath the air you automaticially get infected. That is exactly why the scientists put on the suit and the tape the wrists of their siut and they tape the ankle jut to be very secure that they can not get infected. The last thing that the scientists do so they can honestly secure themselves is using the oxygen so they won't die.
