Question: A carpenter is working on a roof with a 6:12 pitch (26.5 degrees) at a height of 4 metres (13 feet). Which of the following fall protection methods is generally considered inadequate by itself for this task in Canada?
Answer options:
- Full body harness with a shock-absorbing lanyard and anchorage point
- Safety net system below the work area
- Temporary guardrail system meeting OBC/NBC standards ✅ Warning line system 2 metres (6.5 feet) from the leading edge
Correct answer: Warning line system 2 metres (6.5 feet) from the leading edge

For a 6:12 pitch, more robust protection like a harness, nets, or guardrails is required.
