This image is a clear example of how demanding underground utility work can be and why strong safety practices matter on every job.
Relevant WAC codes for work like this include:
WAC 296‑155‑657 — Protective Systems: Requirements for trench protection such as sloping, shoring, shielding, or trench boxes.
WAC 296‑155‑655 — General Excavation Safety: Covers safe access, soil stability, spoil placement, water control, and equipment distance from trench edges.
WAC 296‑155‑615 — Earth‑Moving Equipment Operation: Rules for safe excavator operation, operator training, communication, and worker clearance.
These guidelines exist to protect workers in exactly these kinds of high‑risk environments. Following them consistently helps ensure everyone goes home safe at the end of the day.
