What type of fire extinguishers should not be used on flammable liquid fires?

• A. Foam extinguishers
• B. Water extinguishers
• C. Powder extinguishers
• D. CO2 extinguishers

Answer: (B)

Water extinguishers should not be used on flammable liquid fires because water can spread the burning liquid and exacerbate the fire. Flammable liquids, when combined with water, not only can create a more hazardous situation but also may not effectively suppress the fire. Instead, extinguishers designed for flammable liquid fires, such as foam, powder, or CO2 extinguishers, can smother the flames or displace oxygen, effectively putting the fire out without causing further harm. Foam extinguishers encapsulate the liquid preventing vapors from igniting, powder extinguishers interrupt the combustion process, and CO2 extinguishers displace the oxygen, all of which are effective strategies for extinguishing flammable liquid fires.
