A multipurpose dry chemical extinguisher is rated for which class of fires?

A multipurpose dry chemical extinguisher is designed to effectively combat Class A, B, and C fires. This type of extinguisher is versatile because it can be used on ordinary combustibles (like wood and paper, which fall under Class A), flammable liquids (Class B), and electrical fires (Class C). The dry chemical agent, often monoammonium phosphate, interrupts the chemical reaction in the fire and is effective across these different fire classes, making it a crucial tool for firefighters and for use in various environments where multiple fire hazards may be present.

This capability to handle diverse types of fires is what sets a multipurpose dry chemical extinguisher apart and underscores its importance in firefighting procedures. Understanding the ratings of fire extinguishers helps users select the appropriate extinguisher for the specific type of fire they may encounter, reducing risks and enhancing safety during fire incidents.
