How should a Repair Party Investigator check for heat?

The best method for a Repair Party Investigator to check for heat is by folding the glove back and moving their hand down the door in a "Z" pattern. This technique allows for a safer and more effective assessment of temperature without exposing skin to potential hazards. By using the back of a gloved hand and moving it in a systematic manner, the investigator can gauge heat levels along different areas of the door, helping to identify hot spots that may indicate the presence of a fire or another thermal event behind the door.

This method also minimizes the risk of burns or injury, as direct contact with the door could be dangerous, especially if extreme heat is present. Instead of relying solely on the temperature of the doorknob, which may not accurately reflect hotter areas, this approach ensures a comprehensive check of the door’s surface. Using infrared detection tools can be effective, but in situations where immediate assessment is necessary and such tools are not available, the glove method provides a practical alternative.
