   • Cave-in protection measures are in place.
   • There is a safe way to enter and exit.
   • Equipment and materials are away from the edge.
   • It is free of standing water and atmospheric hazards.
   • Prevent trench collapses:
   • Trenches 5 feet deep or greater require a protective system.
   • Trenches 20 feet deep or greater require a protective system designed by a registered professional engineer.
   • Protective systems for trenches:
   • SLOPE or bench trench walls by cutting back the trench wall at an angle inclined away from the excavation.
   • SHORE trench walls by installing aluminum hydraulic or other types of supports to prevent soil movement.
