Question: A carpenter is working on a roof with a 6:12 pitch. The work requires kneeling and moving across the roof surface to install shingles. What type of fall protection is most appropriate and effective for this specific task, assuming no guardrails are installed?

Answer options:

• A safety net positioned below the work area. ✅ A full-body harness with a fall arrest lanyard anchored to a peak anchor point.
• Warning lines and safety monitors.
• Personal flotation device (PFD) and safety helmet.

Correct answer: A full-body harness with a fall arrest lanyard anchored to a peak anchor point.

Explanation: On a roof with a 6:12 pitch (26.5 degrees), fall arrest systems are generally required whenever there is a risk of falling 3 metres or more. A full-body harness with a fall arrest lanyard anchored to a suitable peak anchor point provides the most effective personal fall protection for a worker actively moving and working on such a sloped surface. Warning lines are typically for flat roofs, and safety nets are a collective protection measure, often used when individual fall arrest is impractical.
