When is a permit-to-work required?

• A. For high-risk tasks such as hot work, confined space entry, or working on energized systems.
• B. For routine, low-risk tasks performed during normal operation.
• C. For tasks that do not involve energy sources.
• D. Only for tasks scheduled during off-peak hours.

Answer: (A)

Permit-to-work is a formal authorization system used to control work that introduces serious hazards. It is essential for high-risk tasks such as hot work (like welding or burning), entry into confined spaces, or working on energized systems because these activities can cause fires, toxic atmospheres, explosions, or electrocution if hazards aren’t properly controlled. The permit ensures hazards are identified, controls are in place (isolation of energy sources, atmospheric testing, fire watches, etc.), qualified supervision is present, and readiness is verified before work starts. Routine, low-risk tasks performed during normal operation are typically managed by standard operating procedures and do not usually require a permit-to-work, though some workplaces may use simpler checklists or specific permits for particular steps. Tasks that do not involve energy sources generally do not require a permit-to-work unless other hazards are present. Scheduling during off-peak hours has no impact on whether a permit is needed.
