2026 Construction Confined Space Training: What OSHA Requires on Site

Frequently Asked Questions

Who must be trained for confined-space work in construction?

Anyone with a role in the entry process or exposure to the hazard needs training matched to that role. That commonly includes entrants, attendants, entry supervisors, testers, certain supervisors, and any designated rescue personnel.

When does OSHA expect confined-space training to happen?

Training must be provided before a worker performs confined-space duties. Retraining is needed when duties change, hazards change, or there is reason to believe the worker’s knowledge is not adequate.

Does confined-space training on a construction site need to be site-specific?

Yes, in practice it should be tied to the actual spaces, hazards, equipment, and trades on the project. Generic awareness training alone is not enough for workers assigned to entry-related duties.

What should be documented after confined-space training?

Employers should document who was trained, when the training occurred, and what topics or duties were covered. Documentation should support the specific roles workers will perform on site.

Why do confined-space problems often show up on construction projects?

Construction sites involve changing conditions, multiple employers, and overlapping hazards. Confined-space controls can break down when permits, atmospheric testing, rescue planning, and nearby trade activities are not well coordinated.
