Step-by-step explanation:
The statement that the first rule of safety when handling firearms is to assume every firearm to be loaded is True. This fundamental rule is crucial for ensuring safety to prevent accidental discharges that may lead to injury or death. Whenever handling firearms, it's important to always follow this rule in addition to others, such as keeping the firearm pointed in a safe direction, keeping your finger off the trigger until you're ready to shoot, and knowing your target and what is beyond it.
Some legal codes, such as those that police could issue one-year licenses for handguns, may include provisions for firearms safety that are related to storage and usage.

These provisions reinforce responsible firearm ownership and usage.
