Confined Spaces in Construction (29 CFR 1926.1200)
Confined space violations in construction address permit-required confined space entry procedures. Workers entering manholes, vaults, tanks, and similar spaces face atmospheric hazards, engulfment, and entrapment risks that require rigorous entry procedures.
What 29 CFR 1926.1200 Requires
Confined space requirements under Subpart AA were specifically written for construction — replacing the previous reliance on general industry standards. The standard requires employers to identify confined spaces, classify which are permit-required, and implement entry procedures with atmospheric monitoring, attendants, and rescue provisions:
- Competent person must identify all confined spaces on the jobsite
- Entry permit system required for permit-required confined spaces
- Atmospheric testing before entry and continuous monitoring during entry
- Attendant stationed outside the space during all entries
- Rescue plan and rescue team or service designated before entry
- Training for all entrants, attendants, and entry supervisors
Most Common Violations
Confined space violations are particularly dangerous because the hazards — toxic atmospheres, oxygen deficiency, engulfment — are invisible. Many confined space fatalities involve would-be rescuers who enter without protection. The most common citations involve the complete absence of a confined space program:
- No confined space identification or assessment on the jobsite
- Entry without a completed entry permit
- Missing or inadequate atmospheric testing before entry
- No attendant stationed outside the confined space
- No rescue plan or designated rescue service
- Inadequate training for entrants and attendants
Penalty Exposure
Penalty range: $1,190–$16,550 per serious violation; up to $165,514 per willful violation
Confined space violations are frequently classified as willful because OSHA considers the hazards well-documented and the protective measures well-established. A willful confined space citation can reach $165,514 in 2026. When a fatality occurs in a confined space without proper entry procedures, criminal prosecution is likely.
The entry permit system provides both worker protection and legal documentation. Completed permits with atmospheric test results, entrant names, and rescue provisions are powerful evidence of compliance during any investigation.
Documentation You Need
Confined space documentation is a multi-layered system — from initial space identification through individual entry permits. Every entry into a permit-required confined space must have its own completed permit:
- Confined space inventory with hazard assessment for each space
- Entry permits completed and signed for each entry
- Atmospheric testing records with calibration documentation
- Training records for entrants, attendants, and entry supervisors
- Rescue plan with designated rescue service contact information
- Annual review of confined space program and permit records
What Inspectors Look For
During an OSHA inspection, confined space operations receive immediate attention. If workers are inside a confined space during the inspection, the compliance officer will verify all elements in real time:
- Completed entry permits — are they current and properly signed?
- Atmospheric monitoring equipment at the entry point — calibrated?
- Attendant presence — is someone stationed outside the space?
- Training records distinguishing entrants, attendants, and supervisors
- Rescue equipment and plan — is a rescue service identified?
- Confined space identification — are all spaces on site assessed?
