What is the purpose of sign-off accountability in PQS?

• A. It eliminates need for safety checks
• B. It ensures accountability lies with the person who verifies task completion and with the supervisor who endorses it
• C. It assigns blame for errors to management
• D. It ensures the trainee is solely responsible

Answer: (B)

Sign-off accountability in PQS creates a documented chain of responsibility by requiring both the verifier and the endorsing supervisor to be accountable for a task's completion. The person who signs off on the task confirms it was performed correctly and safely, while the supervisor who endorses verifies that the trainee meets the required standard and is ready to move forward. This shared accountability preserves safety, ensures quality control, and provides a traceable record of who validated the work. It doesn't eliminate safety checks, assign blame to management, or make the trainee solely responsible.
