Excavation work remains one of the highest-risk activities in construction, with a fatality rate that OSHA consistently cites as more than twice the rate for general construction. The Excavation and Trenching for the Competent Person course prepares designated competent persons to eliminate or control cave-in, engulfment, atmospheric, struck-by, and access or egress hazards before crews enter a trench.

Participants learn how to classify soil using both visual and manual field tests, how to select the correct protective system (sloping, benching, shoring, or shielding), and how to apply tabulated data and engineered designs for excavations deeper than 20 feet. The course walks through the requirements of 29 CFR 1926.651 (specific excavation requirements) and 1926.652 (protective systems), including the duties and authority of the competent person, the inspection cadence before each shift and after any hazard-increasing event, and the documentation expected during OSHA, state-plan, or owner-controlled audits.

Learners also practice recognizing the secondary hazards that account for a large share of trench fatalities: struck-by spoils and equipment, falls into the excavation, hazardous atmospheres from sewer and utility work, underground utility strikes, water accumulation, adjacent structure surcharge loads, and mobile-equipment loading at the edge. By the end of the course the competent person can write a site-specific excavation plan, conduct a compliant daily inspection, stop work when conditions change, and brief the crew on ladder placement, spoil setback, traffic control, and emergency response.

Employers benefit from a defensible training record that supports the qualified-competent-person designation required by 1926.650(b), lowers the likelihood of a serious or willful citation, and reduces the frequency and severity of cave-in, utility-strike, and equipment-related incidents.
