What spacing is specified for flagging around a hazard?

• A. 12 inches apart
• B. 18-24 inches apart
• C. 6 feet apart
• D. 36 inches apart

Answer: (B)

Flagging around a hazard is laid out to create a clear, continuous warning line so the danger stands out and is hard to miss as people approach. Placing flags at 18–24 inches apart provides enough density to prevent large gaps while keeping the line easy to inspect and maintain. If flags were much closer, it would be unnecessarily cluttered and harder to manage; if they were much farther apart, gaps could form that someone might not notice. So the spacing specified is 18–24 inches apart.
