What does a hot door mean?

Answer 1

A hot door typically refers to a door that feels warm to the touch, indicating that there may be a fire on the other side. This can be a crucial sign during a fire emergency, as it suggests that opening the door could allow smoke and flames to enter. In such situations, it's often advised to avoid opening the door and to seek an alternative escape route. Always prioritize safety and alert emergency services if you encounter a hot door.
