Which tasks are critical to be performed before removing bus jumpers?

The correct answer focuses on the importance of safety procedures before removing bus jumpers. Having power removed and verifying that the power removal has been successfully performed is critical to preventing any accidental electrical hazards. This step ensures that no live current is present, which could lead to electric shock or create a risk of electrical arcs when the jumpers are removed. Verifying that the power is removed involves checking circuit indicators, using appropriate test equipment, and following proper lockout/tagout procedures to ensure the work environment is safe for personnel.

While notifying personnel, getting verification from the control center, and documenting the removal process are also important steps in maintaining safety and accountability, they do not address the immediate concern of ensuring that power is indeed removed, which is the foremost priority when dealing with electrical systems. Performing these other tasks becomes relevant after confirming that the area is safe for work.
