Oklahoma One-Call System, Inc. (CALL OKIE) is a non-profit corporation, incorporated in the State of Oklahoma in 1979. CALL OKIE is a valuable tool used in preventing damages to public services. It is a communication link between the excavators and operators of underground facilities. CALL OKIE is a safety and damage prevention program designed to promote public awareness and to eliminate potential hazards posed to excavators, general public, vital underground facilities and the environment, whenever excavation is done.

Excavation damage can cause injury, loss of life and environmental harm. It also causes interruptions to vital services and can involve tremendous repair costs. So please, dig safely and follow these steps:

>CALL BEFORE YOU DIG
   CALL OKIE at one of the following numbers:
   Area wide: (405) 840-5032
   Outside Area wide: (800) 522-6543

>WAIT THE REQUIRED TIME FOR MARKING
   48 hours before you dig
   RESPECT THE MARKS
   DIG WITH CARE

Every day contractors, plumbers, landscapers and homeowners are involved in some type of excavation. Since most facilities in Oklahoma are located underground, excavation activity always carries disaster potential. Prior notification of excavation and location of underground facilities are required by law, and those who choose to ignore requirements for damage prevention are breaking the law.

Most projects are completed on schedule without any site incidents; however, some excavation projects result in substantial damage to property, injury and even death.
