On May 1, 2015, OSHA finalized a comprehensive new rule addressing confined spaces in the construction industry — 29 CFR Part 1926, Subpart AA. This rule is a significant update for construction employers and fills a long-standing gap in worker protection standards.

About the Final Rule

The OSHA Confined Spaces in Construction Final Rule establishes requirements for construction industry employers to protect workers from the hazards of working in confined spaces. A "confined space" is defined as a space large enough for a worker to enter, has limited means of entry or exit, and is not designed for continuous occupancy — such as manholes, tunnels, pipes, vaults, and excavations.

Key Requirements

The rule requires construction employers to:

  • Evaluate work sites for confined spaces before work begins
  • Implement a permit program for permit-required confined spaces
  • Address both atmospheric hazards (such as toxic or oxygen-deficient air) and physical hazards (such as engulfment or moving parts)
  • Provide training for all workers who may work in or near confined spaces
  • Coordinate with other employers working at the same site who may affect confined space conditions

Training Requirement Update

The rule replaces a previous training requirement with a more comprehensive training standard requiring workers to understand the specific hazards they may encounter and the procedures used to protect them.
