What is the recommended distance for hand digging around marked utilities?

• A. Within 12 inches of the marked area
• B. At least 24 inches from the marked area
• C. Typically, within 18 inches of the marked area
• D. More than 36 inches from the marked area

Answer: (C)

The recommended distance for hand digging around marked utilities is typically within 18 inches of the marked area. This approach helps to ensure that workers can safely excavate while being cautious of potential utility lines that may not be accurately represented on maps or may vary in their actual underground locations. This distance allows for a proactive approach in identifying and avoiding damage to the utilities, which is critical for maintaining safety and preventing service interruptions.

While there may be scenarios where a greater distance is needed for specific types of utilities or depending on local regulations or practices, the general guideline emphasizes this 18-inch limit as a balance between safety and practical digging space when working near marked utilities. This ensures that workers can identify and react to any utility lines present while minimizing the risk associated with accidental strikes.
