Locate Buried Utilities
Call Your One-Call System First
Before you start any digging project, contact 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 utility companies or national regulating authority to locate and mark underground
installations. If all utilities are not properly located, 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.
Utilities will then mark their underground facilities by using the following international marking codes:
OSHA CFR 29 1926.651 requires that the estimated location of underground utilities be determined before
beginning excavation or underground drilling operation. When actual excavation or bore approaches an estimated
utility location, the exact location of the underground installation must be determined by a safe, acceptable and
dependable method. If utility cannot be precisely located, it must be shut off by the utility company.
WARNING: Striking an electrical line can cause electrocution. Striking gas line can
cause an explosion. Cutting a fiber optic cable could result in eye damage caused by
laser light. Death or serious injury possible.
Locate utilities before digging. Call 811, 1-888-258-0808, or access www.call811.com
(U.S. only); or contact local utility companies or national regulating authority.
