What is the most common fire suppression system used to combat galley fires?

The most common fire suppression system used to combat galley fires is the local application, pre-engineered wet chemical system. This system is specifically designed for combating fires involving cooking oils and fats, which are often present in galley environments. Wet chemical agents effectively cool the fire and form a barrier between the fuel and the oxygen, often leading to a saponification reaction that helps to extinguish the flames.

Each component of this system is tailored to handle the unique hazards found in kitchens, making it particularly effective compared to other systems like foam, water spray, or standard extinguishers. While foam suppression systems can control some types of fires, including liquid flammable materials, they are not specifically designed for the high-temperature cooking oils found in galleys. Water spray systems can be ineffective or even hazardous when used on grease fires because they can spread the flames. Likewise, while standard fire extinguishers can be used in various fire situations, they do not offer the specialized application and effectiveness of the wet chemical suppression system in dealing with the specific challenges posed by galley fires.
