Complete an Excavation Design Checklist (see page 3 of this procedure) regardless of
location/client facility. One-Call Services must be notified two working days (Monday
through Friday, except holidays) before digging/excavating.
2.1 Before digging/excavating re-contact area One-Call Service for final verification.

The Trained and Certified Competent Person is responsible for:
(A person that is capable of identifying existing and predictable hazards and one who has the authority to take
prompt measures to correct the unsafe conditions).
3.1 All excavations over 4 ft. in depth will be excavated as a type “C” soil with a 1 ½ -1
slope (34 degrees). Any excavation requiring shoring or if an excavation of other type
soil, the Competent Person is responsible for design and contacting the Safety Director
for approval.
3.2 When determined appropriate by the Competent Person, a spotter will be used while
excavating. A probe will be used to locate underground utilities/structures when within
two feet of their estimated depth. Once located, hand digging will be used to visually
expose the utilities or structures that are to be protected from damage. No one is to work
beneath the loads of digging equipment.
3.3 All materials removed from an excavated area must be kept at least 2 ft. away from the
edge of an excavated area. This includes all tools, equipment and any materials that may
be needed in the excavated area. Non-entry areas are to be flagged with red “Danger”
tape.
3.4 A Competent Person shall place barricades at least 6 ft. away from the excavation with
yellow “Caution” tape, or as deemed necessary. Personnel that are exposed to public
vehicle traffic near excavations shall wear reflective warning vests.
3.5 Trenches and excavations that are over 4 ft. in depth require a safe means of access and
escape no more than 25 ft. apart. This can include, but is not limited to, structural ramps,
stairs, ladders and dirt ramps. Walkways over excavations will be secured and include
toe-boards and handrails, use the Scaffolding Safety Procedure, as a reference.
3.6 A Confined Space Entry Permit in conjunction with atmospheric testing must be obtained
before entering excavations over 4 ft. in depth if the Competent Person identifies an
Immediate Danger to Life and Health (IDLH) environment. Use the Confined Space
Policy as a reference.
3.7 Excavations that are below the footing of any foundation or retaining wall shall be
designed by the Competent Person and approved by the Safety Director.
3.8 Daily approval by a Competent Person must be documented for each excavation on an
Excavation Daily Inspection and Entry Permit before any personnel enters. Reinspection must be performed when any condition changes. Personnel shall be protected
from hazards created by water.
3.9 Document Excavation Safety Training shall be kept at the local service area office.
