One of the deadliest jobs in construction is getting safer, and the data backs it up. Worker deaths in trench collapses have fallen nearly 70% since 2022, from 39 that year to 15 in 2023 and about 12 in 2024. That’s a steep drop for a hazard that kills in seconds when a wall lets go.
OSHA points to its excavation National Emphasis Program as the lever. The agency runs more than 1,000 trench inspections a year and has held a zero-tolerance line on unprotected excavations, with immediate inspections and referrals for criminal prosecution where the facts warrant it. The message to contractors has been blunt: shore it, slope it or shield it, every time.
Penalties with teeth
The enforcement isn’t abstract. In a January 2026 case, OSHA found an unprotected excavation along with workers handling suspended loads without hard hats and no barriers at the trench edge. The agency classified the violations as willful and proposed $170,145 in penalties. Cases like it are why the numbers are moving.
The fix hasn’t changed
None of this is new engineering. A trench box, a properly sloped wall, a competent person on site: the protective systems that prevent cave-ins have been required for decades. The shift is enforcement and habit, not technology. See our coverage of the NYCOSH ‘Deadly Skyline’ report on construction fatalities. Source data from OSHA.
