Final answer:
Firefighters should inspect and clean their tools before storing them to ensure they are in good working condition.
Step-by-step explanation:
Firefighters should inspect and put all tools in a ready state before storing. The importance of inspecting the tools is to ensure that they are in good working condition and ready to be used whenever needed. By cleaning the tools, firefighters remove any dirt, debris, or contaminants that may interfere with their performance. Modifying the tools, as mentioned in option B, is not necessary unless there is a need to improve their functionality or repair them.
