Specific Excavation Training Requirements
All excavation surface encumbrances that are located so as to create a hazard to employees must be removed or supported, as necessary, to safeguard employees.
The estimated location of utility installations, such as sewer, telephone, fuel, electric, water lines, or any other underground installations that reasonably may be expected to be encountered during excavation work, must be determined prior to opening an excavation.
Access and egress
Structural ramps that are used solely by employees, as a means of access or egress from excavations, must be designed by a designated Competent Person. Structural ramps used for access or egress of equipment must be designed by a Competent Person qualified in structural design, and must be constructed in accordance with the design. Ramps and runways constructed of two or more structural members must have the structural members connected together to prevent displacement.
Structural members used for ramps and runways must be of uniform thickness.
No employee must be permitted underneath loads handled by lifting or digging equipment. Employees must be required to stand away from any vehicle being loaded or unloaded to avoid being struck by any spillage or falling materials. Operators may remain in the cabs of vehicles being loaded or unloaded when the vehicles are equipped, in accordance with OSHA, to provide adequate protection for the operator during loading and unloading operations.
Warning system for mobile equipment
When mobile equipment is operated adjacent to an excavation, or when such equipment is required to approach the edge of an excavation, and the operator does not have a clear and direct view of the edge of the excavation, a warning system must be utilized such as barricades, hand or mechanical signals, or stop logs. If possible, the grade should be away from the excavation.
