Question 84Safety & Environmental - 1st Asst/Chief

The correct answer is D) the powder is not caked and there is a full charge. When servicing a cartridge-operated dry chemical fire extinguisher, it is important to ensure that the powder is not caked and that there is a full charge. This is because caked powder can reduce the effectiveness of the extinguisher, and a full charge is necessary to ensure that the extinguisher has the appropriate amount of dry chemical to effectively extinguish a fire. The other answer choices are incorrect because they do not address the specific issue of the powder condition and charge level. Checking the pressure gauge and cartridge weight are also important maintenance tasks, but they do not directly address the condition of the dry chemical powder itself.
