Which statement best describes the relationship between energy source verification and task authorization?

• A. They should be completed after starting work
• B. They are optional
• C. They are unrelated
• D. They are part of ensuring proper authorization and energy control before starting work

Answer: (D)

Energy source verification and task authorization are pre-work safety controls that ensure proper authorization and energy control before starting work. Verifying the energy source means confirming that all energy sources are isolated and any stored energy is released or restrained, so equipment cannot unexpectedly energize during maintenance. Task authorization, often part of a permit-to-work system, ensures the person performing the task is authorized and that the job scope, hazards, and required precautions are approved. Together, they guarantee that work proceeds only under the right authority and with the energy safely controlled, preventing injuries from unexpected energization. They are not optional, not done after work starts, and they are directly related to ensuring safety through proper authorization and energy control.
