Free MASS Test Dig Safe Regulations Questions and Answers 1 — Questions and Answers
Question 1: According to Massachusetts Dig Safe law (M.G.L. c. 82, § 40A), what is the minimum required notice an excavator must provide to the Dig Safe system before starting a non-emergency excavation?
- 48 hours, including weekends and holidays
- At least 24 hours, but not more than 30 days
- 72 hours, excluding Saturdays, Sundays, and legal holidays (Correct answer)
- One full business week (5 business days)
Correct answer: 72 hours, excluding Saturdays, Sundays, and legal holidays
Massachusetts law requires excavators to notify Dig Safe at least 72 hours in advance of a planned dig. This calculation specifically excludes weekends and legal holidays to ensure utility companies have three full business days to respond and mark their underground facilities.
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. (Correct answer)
- 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.
The tolerance zone is defined as the width of the utility plus 18 inches on each side. Within this zone, Massachusetts law explicitly prohibits the use of mechanized equipment to prevent damage. Excavators must use non-mechanical means, like hand tools or vacuum excavation, to carefully expose the utility.
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)
Correct answer: White
The American Public Works Association (APWA) Uniform Color Code designates white for marking the proposed area of excavation. This allows the utility locators to know the precise boundaries of the planned work, ensuring they mark all relevant facilities within that scope.
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. (Correct answer)
- 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.
In Massachusetts, Dig Safe markings and the associated ticket are valid for 30 calendar days from the date of issuance. Since more than 30 days have passed, the excavator is legally required to notify Dig Safe again to obtain a new ticket and have the utilities re-marked before any digging can legally begin.
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?
- A project is falling behind its contractual deadline.
- An unexpected sinkhole appears, exposing a broken and leaking sewer main. (Correct answer)
- A homeowner wants to plant a large tree before a weekend party.
- Scheduled replacement of an old, but currently functional, fire hydrant.
Correct answer: An unexpected sinkhole appears, exposing a broken and leaking sewer main.
An emergency is legally defined as a condition presenting an imminent danger to life, health, or property, or requiring immediate correction to restore essential public utility service. A broken, leaking sewer main causing a sinkhole fits this definition. Project deadlines, routine landscaping, and scheduled maintenance do not constitute emergencies.
Question 6: During a site walk-through, an excavator observes several utility markings. Which of the following correctly pairs the utility type with its designated APWA color code?
- Yellow: Potable Water
- Green: Electric Power Lines
- Red: Electric Power Lines (Correct answer)
- Blue: Communications or Cable TV
Correct answer: Red: Electric Power Lines
The APWA Uniform Color Code, used in Massachusetts, designates specific colors for different utilities to prevent confusion. Red is the correct color for electric power lines, cables, conduit, and lighting cables. Yellow is for gas/oil, Green is for sewer/drains, and Blue is for potable water.
