Which type of fire extinguishing system is required for a dispensing area of flammable liquids?

The correct answer is a dry chemical fire extinguishing system, which is specifically effective for extinguishing fires involving flammable liquids. This type of system functions by discharging a dry chemical agent that interrupts the chemical reaction of the fire, effectively smothering it and preventing further combustion.

In a dispensing area for flammable liquids, the risk of fire is heightened due to the presence of these liquids, which can ignite easily. A dry chemical extinguisher is optimal because it is designed to handle Class B fires, which involve flammable liquids like gasoline or oil. It works swiftly and can be used in situations where liquid fires are present, making it suitable for environments such as gas stations or fleet service stations.

While water-based systems can be effective for certain types of fires, they are not suitable for fires involving flammable liquids; water can spread the flames. Foam-based systems can also be effective against flammable liquids by creating a barrier that suppresses vapors and cools the fire, but they require specific conditions for effective use. Gas-based systems may be suitable for certain types of fire suppression, but they generally are not ideal for quickly addressing fires in dispensing areas with flammable liquids. Therefore, a dry chemical system is the most appropriate choice for effective
