Which type of detector is often used in aircraft hangars for early fire detection?

Flame detectors are specifically designed to identify the presence of fire by sensing the infrared or ultraviolet radiation emitted from flames. In environments such as aircraft hangars, where the potential for flammable materials and fuel is significant, early detection of flames is crucial to ensuring safety and preventing extensive damage.

These detectors can respond very quickly to the presence of a fire, allowing for immediate action to be taken, which is especially important in large and open spaces like hangars. They are sensitive enough to detect flames in their early stages, making them more effective than other types of detectors, such as heat or gas detectors, in this particular scenario.

While other detection methods have their places, flame detectors are preferred in aircraft hangars due to their rapid response time and ability to cover large areas, contributing to enhanced safety protocols in aviation environments.
