OSHA

OSHA's excavation standards are found in 29 CFR 1926 Subpart P and apply to all excavation work, including hydrovac operations. Key requirements include having a competent person on site to inspect excavations, providing cave-in protection for excavations deeper than 5 feet, and ensuring safe access and egress for workers entering excavations. Violations of OSHA standards can result in citations and fines ranging from thousands to hundreds of thousands of dollars.

For hydrovac operations specifically, OSHA regulations address several critical safety areas: atmospheric testing in excavations that could contain hazardous gases, confined space entry procedures for workers entering deep or enclosed excavations, traffic control requirements for roadway work, and personal protective equipment requirements for operators.

OSHA provides guidance documents and compliance assistance resources specific to excavation work. Hydrovac contractors should be familiar with OSHA's "Trenching and Excavation Safety" publication and should train all employees on the specific OSHA standards that apply to their work. Regular safety meetings and tailgate talks that address OSHA requirements are a best practice in the hydrovac industry.
