According to the Department of Labor, 39 people died while performing excavation and trench work in 2022 – more than doubling the 2021 total.
Among the procedures listed in DOB’s recent safety advisory:

- Notify DOB of any construction-related incident.
- Follow approved and permitted Support of Excavation documents and don’t deviate from them.
