Blog 3: Permit-to-Work Systems – Controlling Confined Space Hazards

A Permit-to-Work (PTW) system is one of the most effective safety measures for confined space entry. It’s a formal document that ensures no work starts until all HSE confined space requirements are met.

What a Confined Space Entry Permit Includes

• Identification of the confined space location and nature of work.
• Known hazards and risk control measures.
• Authorized worker names and roles.
• Validity time and date.
• Confirmation of rescue and emergency procedures in place.

Why PTW Saves Lives

Many confined space fatalities happen because workers enter without checking air quality, PPE, or rescue readiness. The PTW process acts as a safety checklist, ensuring every hazard is considered before entry.

Best Practices for PTW in Confined Spaces

• Train workers on reading and following permits.
• Display permits at the worksite entrance.
• Revalidate permits if work conditions change.

Golden Rule: No permit, no entry. This simple control prevents countless confined space incidents.
