The correct answer is D. The fire hose should be fully charged before deploying it from the fire station. Explanation: The proper procedure in handling a fire hose requires the hose to be fully charged, meaning the hose is pressurized with water, before it is deployed from the fire station. Partially charging the hose can lead to dangerous situations, as the hose may not be able to withstand the full pressure once it is deployed and can potentially burst or cause other issues. The other answer choices are correct procedures for handling a fire hose, but option D is the only false statement in the given list.
