What action should be taken when a fire extinguisher has been partially used?

When a fire extinguisher has been partially used, it is essential to recharge or service it to ensure it will function properly in the future. A fire extinguisher is designed to discharge a specific amount of its extinguishing agent to effectively combat a fire. Once it has been partially used, the remaining agent may not be sufficient to tackle another fire or may not be reliable due to potential contamination or loss of pressure. Therefore, having it recharged restores its full functionality, ensuring it is ready for future emergencies.

Proper servicing involves checking not only the pressure but also the condition of the extinguishing agent and the entire unit, which is crucial for safety. Regular maintenance by professionals ensures compliance with safety regulations and keeps the equipment in optimal working condition. Simply putting the extinguisher away without recharging or servicing could lead to a hazardous situation if it is needed again and is no longer effective.
