Confined space entry records: 6 permit checks

Key takeaways: what to check today and what depends on the named source

• Verify the written document exists. Confirm you hold the specific written or printed document provided by the employer to allow and control entry, as defined by California DIR / Cal-OSHA. This definition applies to California construction-entry permits and does not establish a universal rule for every jurisdiction.
• Check for the supervisor’s signature. Ensure the entry supervisor identified on the permit has signed it to authorize entry before work begins, a requirement stated in California DIR / Cal-OSHA. Do not assume authorization is implicit; the signature is the recorded evidence.
• Note the time of exit. When a worker leaves the space, record the time of exit on the permit. CCOHS advises that this timestamp should be noted after exiting. This practice supports tracking duration but is not a universal standard.
• Confirm the issuing authority. Verify that the written authority, or confined space entry permit, was issued by the PCBU or person responsible for the work, as described by WorkSafe New Zealand.
• Plan for retention. Remember that canceled permits must be retained for at least one year to facilitate program review, according to California DIR / Cal-OSHA. This retention period is specific to California rules and may differ in other jurisdictions.

How the six record checks fit together

CCOHS describes the entry permit as an administrative tool used to document the completion of a hazard and risk assessment for each confined space entry CCOHS. This definition frames the record as a control document rather than a safety certification. The six checks organize the review sequence: first, record why entry is needed and the assessed risks; second, identify responsible roles; third, review current atmospheric information and its scope; fourth, check authorization, availability, and duration; fifth, check site-specific emergency arrangements; and sixth, record exit and retain the canceled permit. This sequence is an editorial organization for reviewing the existing document. It does not replace the applicable full entry program. The permit records the administrative controls and assessments completed before entry. It does not certify the space as safe based on a single reading or the existence of the document itself. Use the checks to verify that the required information is present and current for the planned job. Mark any missing authorization, duration, role, or emergency information for resolution before entry begins.

Checks 1–2: need for entry and responsible roles

The first two record checks focus on why the work must happen inside the confined space and who holds specific responsibility for that decision. You must review the written record to confirm that the necessity of entry was assessed before any planning began. If the task can be performed from outside the space, the record should reflect that alternative. According to HSE, wherever possible, you should avoid carrying out tasks in confined spaces. If avoidance is not possible, the record must document the specific risks of that particular space. As stated by HSE, if this is not possible, you must assess the risks of the particular confined space and plan how you will control those risks. The permit is not just a signature sheet; it is the administrative evidence that this assessment occurred. It is not a generic form; it is the specific record for that entry.

Mark the specific task description and the name of the qualified entry supervisor on your review sheet. If either is missing, flag it for immediate resolution before any other checks are completed.

Checks 3–4: atmospheric information and current permission

Check 3: review current atmospheric information and its scope. The record must document the specific atmospheric conditions that define the hazard. California Code of Regulations, Title 8, Section 1951 defines an oxygen deficient atmosphere as an atmosphere containing less than 19.5 percent oxygen by volume, according to California DIR / Cal-OSHA. The same California regulation defines an oxygen enriched atmosphere as an atmosphere containing more than 23.5 percent oxygen by volume, according to California DIR / Cal-OSHA. WorkSafe New Zealand notes that the risk of explosion or spontaneous combustion is increased if an oxygen-enriched atmosphere exists where the oxygen content is greater than 23.5%, according to WorkSafe New Zealand. These thresholds are jurisdiction-specific definitions. Verify that the permit lists the measured values and the time of measurement. If the record lacks these specific atmospheric data points, mark the gap.

Check 4: check authorization, availability and duration. The permit must show explicit authorization and be accessible to the workers entering. California Code of Regulations, Title 8, 1954 states that before entry begins, the entry supervisor identified on the permit shall sign the entry permit to authorize entry, according to California DIR / Cal-OSHA. The completed permit shall be made available at the time of entry to all authorized entrants or their authorized representatives, by posting it at the entry portal or by any other equally effective means, so that the entrants can confirm that pre-entry preparations have been completed, according to California DIR / Cal-OSHA. The duration of the permit may not exceed the time required to complete the assigned task or job identified on the permit in accordance with Section 1955(a)(2), according to California DIR / Cal-OSHA. Check that the signature is present before work starts. Confirm the permit is posted or otherwise accessible at the entry point. If the permit lacks a signature or an accessible copy, do not proceed.

Mark any missing signature, threshold value, or duration limit for the entry supervisor to resolve.

Checks 5–6: emergency arrangements, exit and retention

Check 5: verify site-specific emergency arrangements Before authorizing entry, confirm the record includes a plan for what happens if something goes wrong. You should have emergency arrangements where necessary, according to HSE. For every confined space job, have a site-specific emergency procedure and emergency equipment, according to WorkSafe New Zealand. Related site checks include extinguisher travel rules and Portable ladder checks: 4 steps before climbing. The record should show that the procedure is specific to the site and the equipment is present, not just a generic reference. If the permit lists a rescue team or specific gear, note that these are site-specific requirements rather than universal standards.

Check 6: record exit and retain the canceled permit When the work is done, the record must reflect that the worker has left the space. After exiting the confined space, the time of exit should be noted on the entry permit, according to CCOHS. This timestamp closes the loop on the duration of the entry. Once the permit is canceled, the employer must keep it. The entry employer shall retain each canceled entry permit for at least 1 year to facilitate the review of the permit-required confined space program required by Section 1953(a)(14), according to California DIR / Cal-OSHA. This retention period applies specifically to California rules under Title 8, Section 1954.

Editorial recommendation Mark the emergency procedure and equipment on the permit if they are not already listed. Note the exit time as soon as the worker clears the space. File the canceled permit in a location where it can be retrieved for the required review period. You can also record the day on the Construction Daily Log Checklist for Supervisors.

Record requirements by publisher and jurisdiction

The following table organizes record requirements by publisher and jurisdiction. Each row summarizes specific documented practices from the cited sources. These entries reflect the stated scope of each publisher and do not establish a universal jobsite rule.

Review the existing permit against these jurisdiction-specific requirements to identify gaps in documentation, authorization, or emergency planning.

Illustrative example: six marks on one permit

A reviewer has one permit for one planned entry and uses the six checks as a mark-up, not as a new rule. Check 1: the task line is empty, so the necessity of entry is unresolved. Check 2: no supervisor name is on the sheet. Check 3: no measurement time is listed. Check 4: the signature line is blank and no duration is written, so the job waits. Check 5: emergency equipment is not listed. Check 6: exit time is still blank because the entry has not happened. The reviewer marks those six gaps and holds the entry until the signature is present. These marks only illustrate a review of one document. They do not certify the space.

Today’s next step: review the existing record and mark unresolved gaps

Take the existing permit for one planned job and mark missing authorization, duration, role or emergency information for the entry supervisor to resolve before entry. Start by locating the signature line. If that signature is absent, mark the gap and hold the task until the identified supervisor signs.

Next, verify that the completed permit is accessible to the people who will enter. Check whether the permit is physically posted at the portal or provided by another method that lets entrants see the pre-entry status.

FAQ about how to review confined space entry permit records on a construction site

Who signs the entry permit before work starts?

Under California Code of Regulations, Title 8, 1954, the entry supervisor identified on the permit must sign the document to authorize entry before work begins, according to California DIR / Cal-OSHA. This signature requirement applies specifically to the permitting process defined in that section. You should verify that the specific supervisor named on your site’s permit has provided this signature prior to any authorized entry.

Can one oxygen reading prove a space is safe?

A single measurement does not certify a space as safe for entry. California Code of Regulations, Title 8, Section 1951 defines an oxygen-deficient atmosphere as one containing less than 19.5 percent oxygen by volume, according to California DIR / Cal-OSHA. The definition provides a specific threshold for deficiency, but it does not establish a universal rule for safety based on a single data point.

May the permit last longer than the assigned task?

The duration of the permit may not exceed the time required to complete the assigned task or job identified on the permit, according to California DIR / Cal-OSHA. This limit is tied to the specific job description within the permitting process. If the task changes or extends beyond the original scope, the permit duration must be reviewed to ensure it remains consistent with the assigned work.

What should be recorded when a worker exits?

This guidance is part of the confined space program documentation. Recording the exit time creates a clear record of when the individual left the space, which is a standard element of the permit tracking process.

How long does California require canceled construction-entry permits to be retained?

The entry employer shall retain each canceled entry permit for at least 1 year to facilitate the review of the permit-required confined space program, according to California DIR / Cal-OSHA. This retention period is specified in the permitting process regulations.
