OSHA’s Trenching and Excavation Standard

Trenching and Excavation is some of the most dangerous work taking place on a construction site. It’s also some of the most frequently OSHA-cited working conditions, and with good reason – trenching and excavation hazards are easily managed, but can turn deadly in an instant.

The full trenching and excavation standard can be viewed on OSHA’s website.

Cave-ins pose the greatest risk to excavation workers. Just one cubic yard of soil can weight as much as a car. Other trenching and excavation hazards include falling loads, hazardous atmospheres, and hazards from mobile equipment. If a trench is deeper than 20 feet, a registered professional engineer is required to inspect the excavation, to ensure work is being completed safely.

OSHA’s trenching and excavation standard does not require a protective system when an excavation is less than five feet deep or if a competent person determines that the excavation is made entirely in stable rock and found no indication of a potential cave-in.

Check out Appendix A to Subpart P of Part 1926 – Soil Classification for all of the nitty-gritty details concerning the classification of soil and rock deposits.

Never enter a trench unless:

  • It has been properly inspected by a competent person
  • Cave-in protection is in place
  • A safe entrance and exit exists
  • Equipment, materials and machinery are away from the edge of the trench
  • The trench is free of standing water and other environmental hazards

There are many ways to safely comply with the excavation standards. Here are a few of the most popular and effective:

  • Slope the sides of the excavation to an angle not steeper than 1½ : 1. Simply put, for every foot of depth, the trench must be excavated back 1½ feet. This is safe for any soil type.
  • Design a sloping and benching system that follows tabulated data that is approved by a registered professional engineer
  • Use a trench box or shield approved by a registered professional engineer, or one that is designed in accordance with tabulated data and approved by a registered professional engineer
