Confined Space Lockout Tagout (LOTO) Inspection Checklist [FREE PDF]

Lockout/tagout procedures in confined spaces are governed by OSHA 29 CFR 1910.146 in conjunction with OSHA 29 CFR 1910.147, requiring all hazardous energy sources to be isolated, de-energized, and physically locked out before any worker enters a permit-required confined space. NFPA 350 and ANSI Z117.1 further specify that all energy control verifications must be documented and confirmed by the entry supervisor prior to permit issuance. Failure to properly implement LOTO in confined space operati

Hazardous Energy Source Identification

Identify and document all energy sources associated with the confined space prior to isolation.

  • Has a written energy control program specific to this confined space been reviewed prior to entry?
  • Have all electrical energy sources been identified and documented on the energy isolation list?
  • Have all mechanical, pneumatic, hydraulic, thermal, and chemical energy sources been identified?
  • Is there a current equipment-specific energy isolation diagram or P&ID available at the work site?
  • Has the total number of energy isolation points been recorded?

Energy Isolation and Lockout Application

Verify all energy isolating devices have been located, operated, and locked out in the safe (de-energized) position.

  • Have all energy isolating devices been placed in the de-energized (safe) position?
  • Has a physical lock been applied to each energy isolating device by the authorized employee?
  • Does each lock have a uniquely identified tag showing the authorized employee's name and contact information?
  • Has a lockout hasp or multi-lock device been used when more than one authorized employee is involved?
  • Has a photo of all applied lockout devices been taken and attached to the entry permit?

Stored and Residual Energy Control

Confirm all stored, residual, or re-accumulating energy has been relieved, restrained, or otherwise rendered safe.

  • Has all stored electrical energy (capacitors, UPS systems) been discharged or de-energized?
  • Have pressurized lines and vessels been bled, vented, or drained to zero energy state?
  • Have elevated parts, suspended loads, or spring-loaded components been blocked, pinned, or supported?
  • Have thermal hazards (hot surfaces, steam lines) been identified and cooled or isolated?
  • Has a pressure verification reading been recorded at all pressure points confirming zero energy?

Lockout Verification and Testing

Perform verification testing to confirm equipment is fully de-energized and safe for entry.

  • Has the authorized employee verified isolation by attempting to operate the equipment (try-out test)?
  • Has a voltage meter or test instrument been used to verify zero electrical energy at all isolation points?
  • Has the test instrument used for electrical verification been confirmed as functional before testing?
  • Has the entry supervisor signed off on the verification confirming zero-energy state?
  • Have all verification test results and instrument IDs been documented on the entry permit?

Blanking, Blinding, and Line Breaking

Verify physical isolation of piping and utility lines through blanking, blinding, or double-block-and-bleed methods.

  • Have all process piping connections to the confined space been blanked or blinded?
  • Have blind flanges or spectacle blinds been rated for the maximum system pressure and marked accordingly?
  • Has the location and number of all installed blinds been recorded on a blind register or log?
  • Where double-block-and-bleed isolation is used, has bleed valve status been confirmed as open and clear?
  • Has a photo of installed blinds and isolation points been captured and attached to the entry permit?

Entry Permit and LOTO Documentation

Confirm all permit documentation accurately reflects the LOTO controls applied and is properly authorized.

  • Does the entry permit list all energy sources identified and locked out for this space?
  • Has the entry permit been signed by the entry supervisor authorizing entry?
  • Is the entry permit posted at the entry point and visible to all personnel at the site?
  • Have all entrants and attendants been briefed on the LOTO controls in place before entry?
  • Has a LOTO log been initiated to track key issuance, returns, and lock-removal authority for this entry?

Post-Entry LOTO Restoration Procedure

Ensure a controlled and documented process for removing LOTO devices and restoring energy after all personnel have exited.

  • Have all entrants exited the confined space and been accounted for before LOTO removal begins?
  • Have all tools, materials, and equipment been removed from the confined space prior to LOTO removal?
  • Have all installed blinds been removed and the blind register updated to reflect removal?
  • Has each authorized employee removed their own lock from the isolation device?
  • Has the entry supervisor documented LOTO removal completion and permit closure on the entry permit?
