Why is it important to check behind a hot door before opening it?

Checking behind a hot door before opening it is crucial primarily to assess whether it is safe to enter the room. A hot door indicates the possibility of fire on the other side, and opening it without first checking the temperature can lead to a rapid spread of flames or smoke into the area.

By using techniques such as feeling the door with the back of the hand, a firefighter can gauge the temperature and determine whether it is safe to proceed. Additionally, a firefighter could also use a tool to crack the door slightly or observe for any signs of smoke or flames. This thorough assessment ensures that the firefighter can enter safely and effectively without risking their safety or worsening the situation.

The importance of this procedure is rooted in the need for situational awareness, which is critical in firefighting. Knowing the conditions behind the door helps in planning the proper course of action and ensures the safety of the firefighter and any potential victims inside.
