What type of extinguisher should not be used on electrical fires?

• A. Foam extinguishers
• B. Dry chemical extinguishers
• C. Water extinguishers
• D. CO2 extinguishers

Answer: (C)

Water extinguishers should not be used on electrical fires due to the conductive nature of water. When water is applied to an electrical fire, it can conduct electricity, which poses a significant risk of electrocution to the person using the extinguisher. In addition to threatening the safety of the individual, using water in this situation can spread the fire, as water can create steam and potentially cause further ignition of nearby combustible materials. In contrast, other types of extinguishers, such as dry chemical and CO2 extinguishers, are safe for use on electrical fires. They do not conduct electricity and effectively suppress the fire without creating additional hazards. Foam extinguishers can be used with caution depending on the circumstance, but water extinguishers are explicitly not suitable for this type of fire.
