Which extinguisher is commonly used for a Class "C" fire?

A Class "C" fire involves electrical equipment, such as wiring, circuit breakers, and appliances. The use of the correct type of fire extinguisher is crucial for safety. The reason the choice of carbon dioxide is appropriate for a Class "C" fire is that carbon dioxide extinguishers work by displacing oxygen, which is necessary for the fire to continue burning, and they do not conduct electricity, making them safe to use on electrical fires.

Carbon dioxide extinguishers are effective for suppressing flames without leaving a residue that could damage sensitive electronic equipment. This is particularly important when dealing with electrical fires, as other extinguishing agents could pose risks of electrocution or could leave behind substances that might cause further harm or damage to electronic systems.

Understanding the characteristics and appropriate uses of fire extinguishers can greatly enhance safety protocols in environments that involve electrical equipment. Hence, carbon dioxide is the recommended choice when dealing with Class "C" fires.
