What is the required condition for fire extinguishers according to safety standards?

The requirement for fire extinguishers according to safety standards is that they must be fully charged. This condition is crucial because a fire extinguisher is only effective when it is filled with the appropriate extinguishing agent and is ready for use in the event of a fire emergency.

A fully charged extinguisher ensures that it can deliver the necessary suppression agent effectively, which is vital for extinguishing different types of fires safely and reliably. Regular inspections and maintenance are typically part of safety protocols to confirm that extinguishers remain in a charged state and are operational.

In contrast, extinguishers that are empty, deteriorated, or improperly stored do not meet safety requirements and pose a significant risk during an emergency, as they would fail to function effectively when needed.
