How should crews secure themselves when working on a roof during ventilation operations?

• A. Use fall protection (anchors, lifelines, harnesses) and maintain three points of contact; establish a clear escape path.
• B. Run quickly and without protection.
• C. Climb with gloves only.
• D. Sit and wait for instructions.

Answer: (A)

The main idea is keeping workers from falling by using proper fall protection and staying secure on the roof. For ventilation work, that means tying into rated anchors with lifelines and wearing a harness, so a fall is controlled if you slip or lose balance. The harness and lifeline should be chosen for the roof type and slope, and inspected before use. While moving or working, aim to keep three points of contact with the surface to maintain stability and reduce the chance of a slip. Having a clearly planned escape route ready ensures you can retreat quickly if conditions change or if you need to remove yourself from danger.

This approach is essential because it directly addresses the primary hazard on rooftops during ventilation: falls. Rushing without protection exposes you to a free fall. Gloves alone don’t prevent falls, and simply sitting and waiting delays operations and leaves you exposed to evolving hazards.
