What is the purpose of self-checking?

• A. To slow down work to ensure accuracy.
• B. To prevent human errors, especially in tasks that could cause problems if performed incorrectly.
• C. To replace supervisor oversight.
• D. To ensure compliance with paperwork only.

Answer: (B)

Self-checking is about pausing to verify your work so mistakes don’t slip through. Its purpose is to prevent human errors, especially in tasks where an error could cause problems if done incorrectly. In a plant safety setting, taking a moment to confirm steps, measurements, and settings helps protect people and equipment and keeps the process running reliably. This habit supports safety and quality without relying on slowing everything down for no reason; it’s about doing the task correctly the first time. It doesn’t replace supervisor oversight, nor is it only about paperwork—self-checking adds a personal safeguard that catches mistakes you can fix yourself before they become bigger problems.
