What precaution should you take before removing a fuse?

Before removing a fuse, de-energizing the circuit is the most critical precaution to ensure safety and prevent potential hazards. When a circuit is energized and a fuse is removed, there is a risk of electric shock, equipment damage, or short circuiting. De-energizing the circuit eliminates these risks, allowing for a safer working environment.

While checking circuit continuity, wearing protective gloves, and disconnecting the battery can also be important safety practices in various contexts, they do not specifically address the immediate danger posed by an energized circuit when handling fuses. De-energizing the circuit is the most direct and essential step to take prior to any interaction with the fuse.
