Correct Answer:

72 hours, excluding Saturdays, Sundays, and legal holidays

Question 2

An operator has a valid Dig Safe ticket and a yellow line has been painted on the ground, indicating a natural gas pipeline. What is the mandatory procedure for digging within the 'tolerance zone' of this marking?

The operator may use a small backhoe bucket if a spotter is present. Excavation must be performed using non-mechanical means, such as hand digging. Mechanical digging is permitted as long as it does not go deeper than the frost line. The gas company must be on-site to supervise any mechanical excavation.

Correct Answer:

Excavation must be performed using non-mechanical means, such as hand digging.

Question 3

Before notifying Dig Safe for a project, an excavator must pre-mark the proposed area of work. According to the APWA standard used in Massachusetts, what color must be used for this pre-marking?

Red Yellow Blue White

Correct Answer:

White

Question 4

A project's Dig Safe ticket was issued and utilities were marked on April 10th. Due to unforeseen delays, the excavation has not started by May 15th. What is the status of the Dig Safe markings?

The marks are still valid as long as they are clearly visible. The excavator must contact the utility companies directly for verbal approval. The original marks are expired, and a new Dig Safe ticket must be requested for a re-mark. The marks are valid for 60 days, so work can proceed as planned.

Correct Answer:

The original marks are expired, and a new Dig Safe ticket must be requested for a re-mark.

Question 5

Which of the following situations qualifies as an 'emergency excavation' under Massachusetts law, allowing work to begin before the 72-hour notification period has passed?
