What is the first thing you should check before using a Type B extinguisher?

Before using a Type B extinguisher, checking if it is fully charged and in good working condition is critical. This ensures that when you activate the extinguisher, it will function effectively and provide the necessary firefighting capability. A fully charged extinguisher has the correct amount of extinguishing agent and is pressurized correctly, allowing for the optimal range and direction of the discharge. If an extinguisher were to be undercharged or malfunctioning, it could lead to ineffective firefighting efforts, placing the user and others at greater risk in a fire situation.

While knowing the extinguisher type, having support nearby, and ensuring the extinguisher is accessible are also important considerations, the priority is to confirm that the extinguisher is operational and ready to use immediately. This check directly impacts your ability to respond effectively to a fire emergency.
