What safety considerations apply when trenching within the ROW near a roadway?

• A. PPE and daylight operations only.
• B. Trench safety (OSHA) and shielding/shoring; safe distances from traffic; avoiding undermining pavement.
• C. Safe distances only from traffic.
• D. Trench safety (OSHA), shielding/shoring, safe distances from traffic, and avoiding undermining pavement.

Answer: (D)

When trenching near a roadway, safety considerations must address the excavation hazards, protection from traffic, and the integrity of the roadway itself. Excavation work is governed by OSHA, which requires a documented plan and a competent person to oversee daily inspections, steps to prevent cave-ins, and appropriate protective systems. Using shielding or shoring is part of that protective approach to prevent a trench from collapsing and injuring workers. Protecting workers from traffic is another critical piece. Work zones along roadways need clear, effective traffic control to keep vehicles and equipment at a safe distance and to prevent errant vehicle incursions into the work area. This includes barriers, channelizing devices, and proper spacing so workers aren’t exposed to moving traffic or debris kicked up from passing traffic. Finally, you must avoid undermining the pavement. Disturbing the soil beneath or adjacent to a road can compromise the road’s foundation, subgrade, or edge support, leading to pavement failure or collapse. Keeping excavation work and spoil piles away from the pavement edge, ensuring proper backfill and compaction, and planning work to protect the roadway structure are essential. So, a comprehensive approach that includes trench safety per OSHA, shielding/shoring, safe distances from traffic, and avoiding undermining pavement best addresses the risks present when trenching within the ROW near a roadway.
