Trench and Excavation Safety
The Trench and Excavation Safety course provides vital training on managing and securing excavation sites. It covers proper techniques for trenching, hazard identification, and safety measures to prevent collapses and accidents, ensuring safe and compliant excavation operations.
What is the Trench and Excavation Safety?
The Trench and Excavation Safety course from the American Institute of Safety Professionals provides dedicated, in-depth training on OSHA 29 CFR 1926 Subpart P (Excavations), the standard that prevents trench cave-in fatalities. While the Focus Four Caught-In/Between course covers excavation cave-in as one of several caught-in hazards, this dedicated course provides the comprehensive Subpart P competency that excavation competent persons, supervisors, and safety officers need: soil classification methodology, all four protective system types with tabulated data, competent person duties in detail, access/egress requirements, water accumulation management, and the inspection programme that prevents the cave-in fatalities that continue to kill construction workers every year despite being entirely preventable.
Trench cave-in is the most predictable and most preventable cause of construction fatalities. A cubic yard of soil weighs approximately 3,000 pounds. A trench wall collapse buries workers under thousands of pounds of earth with virtually zero survival time. Every trench fatality follows the same pattern: unprotected trench, no competent person inspection, no protective system, and a wall that failed as soil physics predicted it would. This course teaches the soil science, protective engineering, and inspection discipline that breaks that pattern.
The curriculum covers excavation hazards (cave-in, falling into excavations, falling materials, hazardous atmospheres, water accumulation, utility strikes), soil classification per Subpart P Appendix A (Type A, B, C, stable rock, visual and manual tests, layered soils), protective system selection per Appendices B–E (sloping/benching, timber shoring, aluminium hydraulic shoring, trench shields), competent person requirements (daily and event-triggered inspections, soil classification authority, worker removal authority), access/egress (§1926.651(c)(2): ladder, ramp, or stairway within 25 feet of lateral travel), utility location (811/One-Call, hand digging tolerance zones), water accumulation management, fall protection at excavation edges, and the excavation permit system. All training is delivered 100 percent online through Microsoft Teams and the American Institute of Safety Professionals LMS.
Upon completion, graduates receive a certificate, wallet card, and transcript, employer-verifiable at amiosp.com/student-verifications.
