A signal that your gear is superheated is indicated by what?

The correct answer is off-gassing. This phenomenon occurs when the materials in your gear, such as gloves or turnout coats, begin to break down due to exposure to extreme heat. As the synthetic fibers and chemicals used in the manufacture of firefighting gear reach high temperatures, they can produce gases as they decompose, which is known as off-gassing. This is a critical signal indicating that the gear has been subjected to superheated conditions and may not provide adequate protection anymore.

Understanding this aspect is crucial for firefighter safety, as it serves as a warning that the integrity of the gear has been compromised. Recognizing off-gassing can help firefighters make timely decisions about the usability of their equipment in hazardous environments. Monitoring for this sign can significantly mitigate the risks associated with wearing compromised gear.
