Is the confined space entry permit completed, signed, and dated by an authorized entry supervisor?

Is a comprehensive hazard assessment documented, addressing potential atmospheric, physical, and engulfment hazards?

Has the entry team (entrant, attendant, supervisor) been thoroughly briefed on the permit, hazards, and emergency procedures?

Is an entry log available to track entry and exit times for all personnel?

Is a non-entry rescue plan documented and readily available?

Is there a log documenting the inspection of all entry equipment (gas monitors, retrieval systems, PPE) prior to use?

Is the communication system between the entrant and attendant tested and confirmed to be working effectively?

Are isolation procedures (lockout/tagout) verified to be in place for all potential energy sources and flow hazards?

Is the oxygen level within the acceptable range (19.5% - 23.5%)?

Is the H2S level below the permissible exposure limit (PEL) as defined by OSHA?

Are combustible gases below 10% of the Lower Explosive Limit (LEL)?

Is the gas monitor calibrated within the manufacturer's recommended timeframe, and is calibration documented?

Is atmospheric testing documented before entry and at regular intervals during entry?

Are the gas monitor's audible and visual alarms functioning correctly?

Was a bump test performed on the gas monitor prior to entry to verify sensor response?

If ventilation is required, is it in operation and positioned to effectively remove contaminants?

Is the tripod or retrieval system properly set up, stable, and anchored (if necessary)?

Is the retrieval line in good condition, free from cuts, abrasions, or other damage?

Is the entrant wearing a properly fitted full-body harness with a retrieval attachment point?

Is a mechanical advantage system (e.g., winch) available for non-entry rescue?

Is fall protection adequate for the specific entry point and potential fall hazards?

Is the retrieval system rated for the weight of the entrant plus any equipment?

If a self-retracting lifeline (SRL) is used, is it inspected and functioning correctly?

Is edge protection in place to prevent the retrieval line from being damaged?

Are rescue personnel trained in the proper use of the retrieval system?

Is appropriate respiratory protection (e.g., SCBA, supplied air respirator) available and properly fitted if atmospheric hazards cannot be controlled?

Is appropriate eye protection (e.g., safety glasses, goggles) provided and worn?

Are chemical-resistant gloves worn to protect against potential contact with sewage or other contaminants?

Is appropriate protective clothing (e.g., coveralls, Tyvek suits) worn to prevent skin contamination?

Is head protection (hard hat) worn and in good condition?

Is appropriate foot protection (e.g., steel-toed boots) worn?

Is hearing protection available if noise levels exceed permissible limits?

Has all PPE been inspected for damage or defects prior to use?

Are barricades or warning signs in place to prevent unauthorized access to the confined space?

Is emergency contact information readily available at the site?

Is a fully stocked first-aid kit available at the site?

Is a reliable method of communication established between the entrant, attendant, and emergency services?

Has the local rescue team been notified of the entry and potential hazards?

Is adequate lighting provided at the entry point and within the confined space?

Is the ventilation equipment positioned so that it does not create a trip hazard or obstruct the entry point?

Is traffic control in place to protect the entry team from vehicular traffic?
