Trenching and Excavation

Excavating is recognized as one of the most hazardous construction operations. OSHA revised Subpart P, Excavations, of 29 CFR 1926.650, 29 CFR 1926.651, and 29 CFR 1926.652 to make the standard easier to understand, permit the use of performance criteria where possible, and provide construction employers with options when classifying soil and selecting employee protection methods. Trenching and excavation hazards are addressed in specific OSHA standards for the general and Construction industries.

Workers who dig or excavate trenches are at risk of death if they enter an unprotected trench and the walls collapse. However, hazards associated with trench work and excavation are well defined and preventable. The OSHA standard for excavation and trenching, known as 29 CFR* 1926 Subpart P, describes the precautions needed for safe excavation work. There is no reliable warning when a trench fails. The walls can collapse suddenly, and workers will not have time to move out of the way. Even though small amounts of dirt may not seem *Code of Federal Regulations. See CFR in References treacherous, a single cubic yard of dirt can weigh more than 3,000 pounds, which can fatally crush or suffocate workers [Deatherage et al. 2004]. Even small, solid pieces of dirt can cause serious injuries. From 2000-2009, 350 workers died in trenching or excavation cave-ins—an average of 35 fatalities per year [BLS 2010]. Most incidents involve excavation work or "water, sewer, pipeline, and communications and power-line construction" [CDC 2004]. An analysis of OSHA data from 1997-2001 showed that 64% of fatalities in trenches occurred at depths of less than 10 feet [Arboleda and Abraham 2004].

Lack of a protective system was the leading cause of trench-related fatalities in a review of OSHA inspections [Deatherage et al. 2004]. OSHA requires that all excavations 5 feet deep or greater make use of one of the following protective system options. (1) sloping the ground; (2) benching the ground;† (3) shoring the trench with supports such as planking or hydraulic jacks, or (4) shielding the trench (using a trench box). Workers should never enter a trench that does not have a protective system in place designed and installed by a competent person.‡ Factors such as type of soil, water content of soil, environmental conditions, proximity to previously backfilled excavations, weight of heavy equipment or tools, and vibrations from machines and motor vehicles can greatly affect soil † Not all protective systems can be used in all types of soil. Benching cannot be used in Type C soil. ‡ A competent person is one who understands OSHA regulations, can recognize hazards, and is authorized to correct them. Figure 1.

When the sides of trenches are shored, the type of soil and width and depth of the trench affect how far apart the supports should be spaced. Different OSHA regulations apply to the different types of supports used for shoring. Consult 29 CFR 1926 Subpart P Appendices C and D for more information. Appendix F provides a flow diagram for making decisions. Section V, Chapter 2 of the OSHA Technical Manual provides a guide on recognizing and preventing trenching and shoring hazards.
