What information must be on a fire extinguisher's label?

The information that must be on a fire extinguisher's label includes the type of fire extinguishing agent and instructions for use. This is crucial because the fire extinguishing agent indicates the specific types of fires the extinguisher is designed to combat, such as those involving flammable liquids, electrical sources, or ordinary combustible materials. Providing clear instructions for use ensures that individuals know how to operate the extinguisher effectively in an emergency situation, promoting safety and potentially preventing further damage during a fire incident.

While other information, such as the expiration date or manufacturer details, might be relevant for maintenance and regulatory purposes, the most critical information directly related to the effective and safe use of the extinguisher is found in the type of agent and the usage instructions. This emphasis on functionality is essential because, in a fire emergency, clarity and quick access to the right information can save lives and property.
