Why water fire extinguisher is notsuitable for confined electrical machinery room?

A water fire extinguisher is not suitable for a confined electrical machinery room because water conducts electricity, which poses a significant risk of electrocution when used on electrical fires. Additionally, water can cause further damage to electrical equipment and create hazardous conditions. Instead, appropriate extinguishers, such as CO2 or dry chemical types, should be used to safely address electrical fires without the risk of electrical shock or equipment damage.
