Which type of system is commonly used in aircraft hangars to manage fire suppression?

An automatic deluge system is specifically designed for fire suppression in environments like aircraft hangars where large amounts of flammable materials, such as aviation fuel and lubricants, are present. These systems are advantageous because they provide a rapid and extensive water discharge over a wide area, which is essential in combating significant fires that may occur in such facilities.

Automatic deluge systems consist of open sprinklers connected to a water supply, and they activate simultaneously when the detection system identifies heat or smoke. This type of system is particularly effective for protecting high-risk areas, as it can cover large spaces quickly, preventing the spread of flames and minimizing damage.

In contrast, other fire suppression options may not offer the same level of efficiency or coverage. A manual suppression system relies on human intervention, which can introduce delays in response times. A typical sprinkler system may not be equipped to handle the specific fire hazards present in aircraft hangars, and foam suppression systems, while effective for flammable liquids, may not deliver the immediate water flow and coverage provided by an automatic deluge system.
