Permit-Required Confined Space Entry Inspection Checklist [FREE PDF]

Permit-required confined spaces present serious hazards including toxic atmospheres, engulfment, and restricted egress, making strict compliance with OSHA 29 CFR 1910.146 essential before any entry. Employers must issue a written entry permit, verify atmospheric conditions, and ensure rescue services are in place prior to authorizing personnel entry. This checklist guides Entry Supervisors through every pre-entry, active-entry, and post-entry requirement to meet OSHA, NFPA 350, and ANSI Z117.1 s

Space Identification & Hazard Classification

Confirm the space meets the regulatory definition of a permit-required confined space and identify all associated hazards.

Has the space been formally identified and classified as a permit-required confined space?
Is the permit-required confined space sign posted at or near the space entrance?
Have all known atmospheric, engulfment, and configuration hazards been documented?
Has a written confined space program specific to this space been reviewed and is it current?
Have all contractors working in or around this space been informed of the hazards and required coordination procedures?

Entry Permit Completeness Review

Verify the written entry permit contains all required elements before authorizing entry.

Does the entry permit identify the space to be entered, purpose of entry, and authorized duration?
Are the names of all authorized entrants and the assigned attendant listed on the permit?
Are all acceptable atmospheric entry conditions (O2, LEL, toxic) documented on the permit?
Are the results of initial atmospheric tests, including tester name, instrument used, and calibration date, recorded on the permit?
Has the Entry Supervisor signed the permit to authorize entry?
Is a copy of the entry permit posted at the entry point for the duration of the work?

Hazardous Energy Isolation & Lockout/Tagout

Confirm all energy sources have been identified and properly isolated before entry.

Have all mechanical, electrical, hydraulic, and pneumatic energy sources been identified and isolated?
Has lockout/tagout been applied to all energy isolation points per the site LOTO procedure?
Have all lines containing hazardous substances been blanked, blinded, or double-blocked and bled?
Has the space been purged, flushed, or ventilated as required to eliminate hazardous atmospheres?
Has engulfment hazard (bulk material, liquid) been controlled by blocking, blinding, or draining?

Pre-Entry Atmospheric Testing

Document atmospheric test results in the order prescribed by OSHA regulations.

Is the atmospheric testing instrument calibrated and bump-tested within the manufacturer's recommended interval?
Is the oxygen concentration between 19.5% and 23.5% throughout the space?
Is the flammable gas/vapor concentration below 10% of the Lower Explosive Limit (LEL)?
Are toxic substance concentrations below applicable OSHA PELs or ACGIH TLVs?
Were atmospheric tests performed at multiple levels (top, middle, bottom) within the space?
Is continuous atmospheric monitoring equipment deployed inside the space for the duration of entry?

Ventilation & Personal Protective Equipment

Confirm ventilation controls and appropriate PPE are in place before entry begins.

Is mechanical ventilation (forced-air blower) operational and positioned to supply fresh air to the entrant's breathing zone?
Is combustion-powered equipment (generators, pumps) positioned to prevent exhaust from entering the space?
Have all entrants been issued and fitted with the required PPE (hard hat, gloves, chemical-resistant clothing) for identified hazards?
Is supplied-air or SCBA respiratory protection available and required for this entry?
Is each entrant equipped with a personal multi-gas monitor with audible and visual alarm?

Attendant Duties & Rescue Preparedness

Verify the assigned attendant is positioned, equipped, and that rescue services are confirmed and ready.

Is the assigned attendant stationed outside the space and maintaining continuous communication with all entrants?
Does the attendant have a current list of all authorized entrants and is tracking entry/exit?
Is non-entry rescue equipment (retrieval system, tripod, lifeline, harness) staged at the entry point?
Has a rescue service (on-site or external) been notified and confirmed available for the duration of the entry?
Does the attendant have the means to summon rescue without entering the space?
Is first aid/AED equipment accessible and is at least one qualified first-aid provider on site?

Entrant Authorization & Pre-Entry Briefing

Confirm all entrants are trained, authorized, and have received a site-specific pre-entry safety briefing.

Have all authorized entrants received documented training on confined space hazards and emergency procedures?
Has a pre-entry safety briefing covering space-specific hazards, atmospheric conditions, and rescue procedures been conducted?
Do all entrants understand and know the evacuation signal and exit procedure?
Have all entrants been fitted with a full-body harness connected to the retrieval lifeline?
Have all entrant signatures been obtained on the entry permit to acknowledge hazard awareness?

Post-Entry Permit Cancellation & Closeout

Ensure the entry permit is properly cancelled and lessons learned are documented after work is complete.

Have all entrants exited the space and been accounted for before the permit is cancelled?
Has the entry permit been cancelled and marked with the cancellation date and time?
Has all rescue equipment, monitoring instruments, and tools been accounted for and removed from the space?
Has the space been re-secured or barricaded to prevent unauthorized re-entry?
Were any problems encountered during entry documented and reported for program review?
