Trench & Excavation

Posted on Jul 11, 2023 in Main

HIOSH and OSHA is focusing on reducing trenching and excavation hazards. Trench collapses, or cave-ins, pose the greatest risk to workers’ lives. To prevent cave-ins:

  • SLOPE or bench trench walls
  • SHORE trench walls with supports, or
  • SHIELD trench walls with trench boxes

Employers should also ensure there is a safe way to enter and exit the trench. Keep materials away from the edge of the trench. Look for standing water or atmospheric hazards. Never enter a trench unless it has been properly inspected.

29 CFR 1926.65029 CFR 1926.651, and 29 CFR 1926.652 are applicable OSHA standards (incorporated into HIOSH standards)
