What could occur if water-based substances are used to extinguish electrical fires?

Using water-based substances to extinguish electrical fires can lead to receiving an electrical shock for several reasons. Water is a conductor of electricity, and when it comes into contact with energized electrical equipment, it can allow the electrical current to flow through the water. If a person is using water to try and extinguish an electrical fire, the current could travel through the water and potentially lead to an electrical shock.

Additionally, electrical fires often involve live wires or malfunctioning equipment, and the introduction of water can create unsafe conditions that increase the risk of electrocution. Therefore, it's crucial to use appropriate extinguishing agents, such as dry chemical extinguishers specifically designed for electrical fires, instead of water-based substances to ensure safety.
