Extinguisher Type B (TFM02) 2025 – 400 Free Practice Questions to Pass the Exam

The proper method to verify the amount of recharge agent used when recharging an extinguisher is by weighing. This approach ensures an accurate measurement of the recharge agent, as manufacturers typically specify the exact weight of the agent required for each type of extinguisher. Weighing allows for precise compliance with the manufacturer's specifications, which is crucial for the extinguisher's effectiveness and safety.

Visual inspection would not provide an accurate assessment of the amount of agent inside the extinguisher, as it could lead to misjudgment. Measuring by volume can also be unreliable because different agents have varying densities, which makes it difficult to determine the correct amount without the proper weight. Likewise, a pressure test does not directly correlate with the amount of recharge agent present, and it could potentially miss discrepancies in the agent quantity.

Therefore, using weight ensures that each extinguisher is equipped with the correct amount of agent, aligning with safety standards and performance expectations.
