Which method is recommended for checking hot doors and hatches?

The recommended method for checking hot doors and hatches is to use the back of your hand. This technique allows you to gauge the temperature effectively while minimizing the risk of burns. The skin on the back of the hand is more sensitive compared to the palm, making it a safer choice for testing temperature without direct skin exposure to high heat.

When using the back of your hand, you can approach the surface cautiously, allowing for a quick withdrawal if the temperature is too high, thus reducing the chances of injury. This technique is important in safety protocols, especially in environments where heat may be hazardous.

While other methods such as using a temperature gauge or a thermal imaging camera are effective for precise measurements, they may not be as readily available in every situation. Employing the palm of your hand is less advisable due to its sensitivity and higher risk of burns, making the back of the hand the most practical and safe method for quickly assessing potentially hazardous heat levels.
