What must you check before using a fire extinguisher?

Before using a fire extinguisher, it is essential to check that it is charged and operable. This ensures that the extinguisher is in proper working condition and contains the necessary agent to effectively combat the fire. A charged extinguisher indicates that there is enough pressurized extinguishing agent available, while operability confirms that the nozzle and other mechanisms function correctly.

Using a non-charged or malfunctioning extinguisher could lead to failure in containing or extinguishing the fire, thereby putting the user and others at risk. Regular inspections and maintenance checks should be part of standard safety protocols to ensure that firefighting equipment is always ready for use when needed.
