Show answer & explanationAnswer & explanation
Correct answer: B. Following the reverse order of erection, component by component

Why the other options are wrong
- A. Workers must continue to use fall protection during dismantling, especially when working at heights.
- C. Dropping scaffold components is unsafe and can cause damage to equipment or injury to workers on the ground.
- D. Removing all guardrails simultaneously compromises fall protection and is extremely dangerous.
