Which detectors are typically used in high hazard areas?

Flame detectors are specifically designed to identify the presence of flames, making them particularly effective in high hazard areas where flammable materials are present or where rapid ignition could lead to dangerous situations. They work by detecting the ultraviolet (UV) or infrared (IR) radiation emitted by flames, allowing for quick response to potential fire hazards. This rapid detection is crucial for areas where the risk of combustion is heightened, ensuring that emergency measures can be initiated swiftly to mitigate the threat.

In comparison, smoke detectors are more suited for early detection of smoldering fires and may not respond as effectively in environments that are prone to conditions that could hinder smoke formation. Photoelectric detectors, while useful for certain types of fires, are also not as effective in high hazard atmospheres compared to flame detectors, as they rely on the presence of smoke particles rather than direct flame detection. Heat detectors can detect increases in temperature but may not respond quickly enough to flaming situations, making them less suitable than flame detectors for immediate identification of fire in high risk settings.
