Before opening a door when fire is suspected on the other side, you should feel the?

Before opening a door when fire is suspected on the other side, feeling the top of the door is a crucial step. This is because the heat from a fire rises, so checking the top helps you assess whether there is significant heat and potentially a fire source just on the other side. If the top of the door is hot, it indicates that it may be unsafe to open the door due to potential flames or rapidly spreading heat.

Feeling the bottom of the door, the door knob, or the door jamb also provides important information, but they are not as effective as checking the top. The door knob could be hot, indicating heat from a fire, but the heat might not have fully penetrated to the lower area of the door yet. The door jamb could also be checked, but the upper part of the door is a more direct indicator of what to expect as you open it. Checking the top is part of a systematic approach to ensure your safety and that of others before entering a potentially dangerous environment.
