Trench & Excavation Safety Training in Phoenix, AZ
OSHA 1926 Subpart P-compliant trench and excavation safety training for construction employers across Arizona — group and corporate bookings for crews of any size, at your jobsite or our Phoenix training facility.
Cave-Ins Are Among the Most Deadly Construction Hazards
Trench cave-ins kill dozens of workers every year and injure hundreds more. A cubic yard of soil weighs up to 3,000 pounds — an unprotected trench can collapse without warning, leaving no time to react. OSHA 1926 Subpart P requires that every excavation five feet deep or greater be protected by an adequate protective system, and that a trained Competent Person inspect the excavation daily and after any event that could affect its stability.
P3 Safety Solutions delivers trench and excavation safety training to construction contractors, utility companies, municipalities, and excavation subcontractors across Phoenix, Arizona, and the Southwest. We offer both awareness-level courses for workers who work in and around excavations, and the full Competent Person course for the supervisors legally required to be on site.

Built for Construction Employers in Arizona
Our trench and excavation safety training is used by general contractors, excavation and grading subcontractors, utility and pipeline contractors, municipal public works crews, and any employer whose workforce digs or works in trenches. Arizona's construction market — including water and sewer infrastructure, commercial site development, and telecom underground installation — puts crews in excavations regularly. Every one of those jobs requires a trained Competent Person on site before work begins.
We deliver group courses at your jobsite or facility anywhere in Arizona, or at our Phoenix Safety Training Center. The Competent Person course can incorporate practical soil classification and protective system exercises on an actual excavation at your site. Contact us to discuss scheduling and on-site logistics.
