Interragator II GPR System Safety Messages 10-3
Before you start any digging project, don’t forget to call the local One-Call system in your area and any utility
company that does not subscribe to the One-Call system. For areas not represented by One-Call Systems
International, contact the appropriate utilities company or national regulating authority to locate and mark the
underground installations. If you don’t call, you may have an accident or suffer injuries; cause interruption of
services; damage the environment; or, experience job delays.
The One-Call representative will notify participating utility companies of your proposed digging activities. If
you are in the U.S. or Canada, and do not know the number for the local One-Call representative in your area,
dial the North American One-Call number, 1-888-258-0808, for this information. Utilities will then mark their
underground facilities by using the following international marking code:
WARNING: Always contact your local One-Call system before the start of your digging
project. The Interragator II GPS system is intended to be used with other utility locating
methods, such as the use of the One-Call system and potholing.
Electric shock or gas explosion can kill.
