5.14 Contact Names and Numbers


Practice Statement:

The excavator’s designated competent person at each job site has access to the names and phone numbers of all facility owner/operator contacts and the one call center.

Practice Description:

Situations arise on the job site that require immediate notification of the facility owner/operator, one call center, or local emergency personnel. To avoid costly delays, the excavator ensures that the designated job site personnel have all appropriate names and phone numbers. If telephone communication is unavailable, radio communication to the “home office” is available so that timely notification can be made. The “home office” also has immediate access to all appropriate names and telephone numbers.
