Trenching & Excavation Safety

Compliance with OSHA’s Trenching & Excavation Standards saves lives, and can help your company avoid costly OSHA citations & Penalties.

OSHA’s excavation standard requires your company to have a “Competent Person” on the site during critical operations, and all employees must be trained on the hazards of trenching & excavation work.

AGC Safety Training Program:


Trenching & Excavation

“Competent Person Training”

Training time: 4 Hours. Information to be presented: There is no excuse for a worker to be hurt or killed by a cave-in. OSHA regulations (1926.651) require that all “daily inspections of excavations, the adjacent areas, and protective systems shall be made by a competent person for evidence of a situation that could result in possible cave-ins, indications of failure of protective systems, hazardous atmospheres, or other hazardous conditions. An inspection shall be conducted by the competent person prior to the start of the work and as needed throughout the shift.” This course provides the knowledge to meet this requirement.
