Key prevention

  • Always utilize certified shoring, shielding, or sloping methods before any worker enters an excavation site.
  • Keep heavy equipment and excavated soil piles well back from the trench edge to prevent structural overloading.
  • Conduct daily inspections of the excavation and surrounding areas to identify signs of shifting soil or water accumulation.
  • Ensure there is a safe and unobstructed means of egress, such as a ladder or ramp, located within a short distance of all employees.
  • Train your crew to recognize the warning signs of soil instability and empower them to stop work immediately if conditions change.
