Final answer:
The statement is true; while using safety mechanisms is important, one should never solely rely on them and should always practice comprehensive safety measures.
Step-by-step explanation:
The statement 'It is a good idea to always use the safety, but never rely on it' is true. While safety mechanisms such as safety catches on equipment or procedures are crucial, one should not rely solely on them. It is always best to follow comprehensive safety practices. This includes not performing experiments alone, always checking the safety data of any chemicals, and following instructions precisely. Let's consider an example from rock climbing: even if a climber's equipment has a safety mechanism, they should always double-check their gear, as relying solely on the safety could lead to a false sense of security and dangerous situations.
