4.1.1 Underground utilities
Before starting excavation work, determine whether any utility installations such as sewer, telephone, fuel, elec-
tric, or water lines, may be encountered. Utility companies and owners must be contacted to locate utility instal-
lations.
When the excavation operations approach the estimated location of the underground installation, the exact loca-
tion must be determined by safe and acceptable means.
While the excavation is open, any underground installation must be protected, supported or removed as neces-
sary to safeguard employees.
4.1.2 Excavations
Before entering trenches, pits or other excavations, the following conditions must be met:
• The applicable safety laws, regulations, and guidelines for excavations are understood and followed.
• Be aware that site conditions can change rapidly, for example due to heavy rain, rapid thaw, vibrations or
other factors.
• Do not work in an excavation or trench unless it is properly protected against collapse. Examples of protec-
tion systems are shown in the following figures.

• Regularly check the walls of an excavation or trench for cracks, bulges and spalling. Check the shoring for
signs of distress, especially after a rainstorm.
• Do not work in an excavation that is filled or partially filled with water. Remove personnel from the excavation
during a rainstorm, and inspect the excavation carefully before re-entry.
• Do not store excavated material and equipment along the edge of the trench or excavation. Do not drive or
park vehicles along the edge of an excavation.
