OSHA to Increase Awareness of Trench-Related Hazards

Excavation and trenching are among the most hazardous construction operations. The Occupational Safety and Health Administration’s (OSHA) Excavation standards, 29 Code of Federal Regulations (CFR) Part 1926, Subpart P, contain requirements for excavation and trenching operations.

OSHA’s Agency Priority Goal for 2018 aims to reduce trenching and excavation hazards. According to the Bureau of Labor Statistics, excavation and trench-related fatalities in 2016 were nearly double the average of the previous five years.

The primary hazard of trenching and excavation is employee injury from collapse. Soil analysis is important in order to determine appropriate sloping, benching, and shoring.

Additional hazards include:

  • Working with heavy machinery;
  • Manual handling of materials;
  • Working in proximity to traffic;
  • Electrical hazards from overhead and underground power lines; and
  • Underground utilities, such as natural gas.

OSHA plans to issue public service announcements, support the National Utility Contractors Association’s 2018 Trench Safety Stand Down, update online resources on trench safety, and work with other industry associations and public utility companies to create an effective public-private effort to save lives.

OSHA’s trenching and excavation national emphasis program is also currently under revision.
