Study Notes

Dig Safe Overview

  • Dig Safe® is a not-for-profit organization facilitating communication between excavators and utility companies regarding excavation projects.
  • It offers a free service to notify relevant utilities for marking underground lines.

Contact Information

  • Dig Safe phone number: 811 or 1888-DIG-SAFE.

Notification Requirements

  • Advance notice for excavation must be given at least 72 hours prior, excluding weekends and holidays.
  • Emergency notifications are required as soon as possible, with no emergency ticket needed unless it is a true emergency.

Definition of Excavation

  • Excavation involves earth movement or removal by powered equipment, excluding human or animal-powered tools and agricultural tilling.

Marking and Premarking

  • Premarking the excavation area is essential using white paint, flags, or stakes, with the company's identification included.
  • A single stake can be used to mark smaller excavation sites (50' radius or less), detailing the excavator's name and site radius.

Ticket Management

  • Obligation to maintain utility marks at the excavation site falls on the excavator.

Safety Protocols

  • If markings are compromised, establish offset marks and communicate with all personnel involved.

Gas Leak Recognition

  • Gas leaks can be detected by smell (distinctive odor added for safety), sight (white clouds, dying vegetation), or sound (roaring, hissing noise).
  • In case of a suspected gas leak, evacuate the area and call 911, avoiding actions that could ignite gas.

Pipeline Safety Measures

  • Pipeline safety includes coordination with One Call Centers, comprehensive inspections, workforce qualifications, and public education on excavatory safety.

  • Color coding system for utility types:
    • Yellow: Gas, Oil, Steam, Petroleum
    • Orange: Communication lines
