Entry Permit and Authorization

Verify permit issuance per OSHA 1910.146(f).

  • Has space been evaluated and classified as permit-required (atmospheric hazard, engulfment, entrapment, other recognized hazard)?
  • Is written entry permit issued and signed by Entry Supervisor with all required sections completed?
  • Is trained attendant assigned to remain outside space for entire duration of entry?
  • Is non-entry rescue procedure established before entry begins (tripod with lifeline or mechanical retrieval)?
  • Is procedure in place to cancel permit and require evacuation if unanticipated hazard is detected?

Atmospheric Testing and Monitoring

Test atmosphere per OSHA 1910.146(d)(5).

  • Is oxygen concentration between 19.5-23.5% as required by OSHA 1910.146?
  • Are flammable gas concentrations below 10% of Lower Explosive Limit?
  • Are all toxic substances below PELs for CO, H2S, and other specific contaminants?
  • Is continuous monitoring in place for atmospheric hazards for duration of entry?
  • Has atmosphere been tested at multiple depths and locations accounting for stratification of heavier gases?

Isolation and Hazard Control

Verify hazard isolation per OSHA 1910.146(d).

  • Are all energy sources (electrical, mechanical, pneumatic, hydraulic) locked out and tagged per LOTO procedures?
  • Are all pipes and lines blanked, blinded, or disconnected to prevent inadvertent flow into space?
  • Has space been purged and ventilated before entry to achieve safe atmospheric levels?
  • Are free-flowing materials (grain, sand, ore) controlled to prevent engulfment during entry?

Entrant PPE and Communication

Verify entrant equipment per OSHA 1910.146(d)(4).

  • Is entrant wearing full-body harness with retrieval line attached to mechanical retrieval device outside space?
  • If IDLH atmosphere possible, is entrant equipped with SCBA rather than air-purifying respirator?
  • Is two-way communication between entrant and attendant maintained throughout entry?
  • Has entrant been trained on confined space hazards, permit requirements, and emergency procedures?
