Trench collapse is one of the most preventable serious construction injuries — and one of the most prosecutable under Labor Law §241(6).
TL;DR
- Trench and excavation collapse injuries trigger workers’ compensation against the employer plus Labor Law §241(6) claims against owners and general contractors for Industrial Code violations.
- NY Industrial Code 23-4 governs excavation work. Violations are typically clear and well-documented post-incident.
- OSHA 29 C.F.R. §1926 Subpart P requires shoring, sloping, or shielding in trenches over 5 feet deep — and these violations are routinely the cause of collapse injuries.
- Common injuries: crush, asphyxiation, fracture, fatal injuries.
Mechanism
Soil is heavier than most workers realize — roughly 100 pounds per cubic foot. A cubic yard of soil weighs about 2,700 pounds. A trench cave-in instantly buries the worker with hundreds to thousands of pounds, producing crush injuries, asphyxia, and rapid fatalities.
Labor Law §241(6) violations
The Industrial Code provisions most often cited:
- 12 NYCRR 23-4.2 — sloping, benching, or shoring of trenches over 5 feet
- 12 NYCRR 23-4.4 — protective systems
- 12 NYCRR 23-4.5 — utility-line work requirements
- 12 NYCRR 23-1.7 — protection from falling objects
OSHA Subpart P requirements track largely the same. Violations are typically findable in post-incident OSHA investigations.
Common scenarios
- No shoring or shielding in trench over 5 feet
- Inadequate shoring for soil type
- Material stockpiled too close to trench edge (within 2 feet)
- Equipment or vehicle vibration triggering collapse
- Water infiltration weakening trench walls
- Spoil pile collapse burying workers
Injuries
- Crush injuries — chest, abdominal, pelvic
- Asphyxia
- Fracture — particularly spine, pelvis, lower extremity
- Closed head injury
- Internal injuries
- Fatal injuries
What to do next
Trench collapses are typically investigated by OSHA promptly. The OSHA report and any DOB or DEP findings are critical evidence. Contact me directly — these cases often involve multiple potential defendants (employer, GC, excavation contractor, equipment provider).
Frequently asked questions
Why are trench collapses preventable?
Soil weighs about 100 pounds per cubic foot. Industrial Code §23-4 and OSHA Subpart P require shoring, sloping, or shielding for trenches over 5 feet. When these requirements aren’t met, collapses occur — and Labor Law §241(6) claims against owners and contractors typically succeed because the Code violation is well-documented post-incident.
What’s the typical cause of a trench collapse?
No shoring or inadequate shoring for soil type, material stockpiled too close to the trench edge, equipment vibration triggering wall collapse, water infiltration weakening walls, or spoil pile collapse. Each is a typical Industrial Code violation.
