What is the function of a heat sensor label on a ladder?

The function of a heat sensor label on a ladder is to change color when exposed to a specific degree of heat. This technology is designed to provide a visual indication of whether the ladder has been subjected to excessive temperatures that could weaken its structural integrity. When the heat sensor responds to high temperatures, it changes color, alerting firefighters and other users to the potential hazards of using the ladder after it has been compromised.

This feature is crucial in ensuring safety, as it helps workers quickly assess whether equipment is still safe for use after exposure to conditions that may have reduced its strength. Proper understanding and use of heat sensor labels can prevent accidents and ensure that firefighters utilize safe and reliable equipment during their operations.
