Massachusetts Hoisting License Practice Test

What is indicated by white lines, flags, or stakes in a work area?

1. Hazard warnings

2. Pre-mark lines for Digsafe

3. Area for equipment storage

4. Delimitations for pedestrian access

The correct answer is: Pre-mark lines for Digsafe

The presence of white lines, flags, or stakes in a work area primarily indicates that these markings are pre-mark lines for Digsafe. Digsafe is a program in Massachusetts designed to promote the safe digging practices by notifying utilities of upcoming excavation work. When a contractor plans to dig, they must call Digsafe, which then instructs utility companies to mark their underground lines in order to prevent accidental damage. The white markings serve as a visual guide to ensure that workers are aware of where underground utility lines are located, helping to mitigate the risk of accidents and damages during excavation. Other choices, while they might sound plausible, do not align with the specific use of white markings. Hazard warnings would typically employ different colors, and equipment storage areas would not be designated through such markings. Similarly, delimitations for pedestrian access are more likely to be marked with specific safety signs or barriers rather than just white lines, flags, or stakes. Thus, the indication of white lines, flags, or stakes as pre-mark lines for Digsafe aligns accurately with industry standards and safety practices.
