  1. 6 feet
  2. 10 feet ✔
  3. 15 feet

Why: 1926.451(g)(1) requires scaffold fall protection at heights above 10 feet, using guardrail systems or personal fall arrest.

Huh, didn't know that: The scaffold trigger height is different from the general 6 foot construction fall protection trigger.

Why did the scaffold get a raise? It was above the lower level.
