A confined space entry permit is a written authorization required under OSHA's Permit-Required Confined Spaces standard (29 CFR 1910.146) before an employee enters a space with known or potential atmospheric, engulfment, or entrapment hazards. It documents hazard testing, isolation steps, authorized entrants, and rescue procedures, is signed by a trained entry supervisor, and is valid for one shift only. Below is what the permit actually has to include, and a free template.
I checked what's currently ranking for this search before writing anything. Position two and three are raw PDFs straight off osha.gov and gsa.gov. Right underneath them is a wall of Google Shopping results for printable permit tags running $12 to $58. There's no small-business-focused explainer in the top results, and nothing that walks through the standard in plain language while still giving you something usable. That's the gap this post fills.
What Actually Requires a Permit
Not every enclosed space is a "permit-required confined space" under 29 CFR 1910.146. OSHA's definition has two layers, and mixing them up is the single most common mistake small crews make:
| Classification | Definition | Permit Required? |
|---|---|---|
| Confined space | Large enough to enter and work in, has limited or restricted means of entry/exit, and isn't designed for continuous occupancy (tanks, silos, pits, vaults, crawl spaces, sewers) | Not automatically; this is just the baseline definition |
| Permit-required confined space | Meets the confined space definition and contains, or could contain, a hazardous atmosphere, an engulfment hazard, an internal shape that could trap or asphyxiate an entrant, or any other recognized serious safety or health hazard | Yes, a permit is required before every entry |
| Non-permit confined space | Meets the confined space definition but has no hazard that could cause serious harm | No, but reclassifying a former permit space still requires its own documentation under 1910.146(c)(7) |
A storage tank that once held a hazardous chemical doesn't stop being a permit space just because it's empty and looks clean. Residual vapor, oxygen displacement, and off-gassing from whatever coated the walls are exactly the kind of atmospheric hazard the standard is written around. When in doubt, test first and assume it's a permit space until air monitoring says otherwise.
What the Permit Itself Must Include
1910.146(f) lists what has to be on the permit before anyone enters. Small crews tend to get the hazard-identification section right and skip the operational details underneath it:
| Required Element | What Goes On the Permit |
|---|---|
| Space identification and purpose | Which specific space, and why entry is needed that day |
| Date and authorized duration | The permit is only good for the task and shift described, not open-ended |
| Authorized entrants and attendant | Named individuals, not job titles ("the second-shift crew" isn't sufficient) |
| Entry supervisor | Named and signed, responsible for verifying every other line item before authorizing entry |
| Hazards of the space | Every hazard identified, atmospheric or physical, specific to that space and task |
| Isolation methods | Lockout/tagout, blanking, blinding, or disconnection steps completed before entry |
| Acceptable entry conditions | The oxygen, flammability, and toxicity readings that must be met before entry is authorized |
| Test results, with initials and time | Actual atmospheric readings recorded at the time of testing, not "checked, OK" |
| Rescue and emergency services | How to summon help, and whether it's an in-house rescue team or a called-in service |
| Communication procedures | How the attendant and entrants stay in contact throughout the entry |
| Equipment required | PPE, testing and monitoring equipment, communication devices, alarm systems, and rescue/retrieval equipment |
| Additional permits | Any related permit needed for the same job, such as a hot work permit for cutting or welding inside the space |
The line most permits get wrong isn't a missing signature. It's the test results row. "Atmosphere tested, acceptable" with no numbers doesn't hold up. OSHA wants the actual oxygen percentage, LEL reading, and toxic gas concentration logged with a time stamp, because that's the data that proves the space was safe to enter at the moment someone went in, not just that a meter was pointed at the opening at some point that day.
The Entry Supervisor's Role
1910.146 puts one named person on the hook for every entry: the entry supervisor. This isn't automatically the site foreman or the most senior person around. It's whoever is trained for the role and takes responsibility for confirming, before signing the permit, that isolation is complete, testing has been done and meets the acceptable conditions listed, rescue and communication procedures are in place, and every authorized entrant actually knows the plan. That same person also has the authority to cancel the permit and pull entrants out immediately if a condition changes that isn't covered by what's already on the permit, a duty that matters more than the signature itself.
On a small crew, this is often the site supervisor or foreman wearing a second hat, not a dedicated safety manager. That's fine under the standard, provided the person has the training to actually evaluate the conditions rather than just sign where indicated.
How Long a Permit Stays Valid
A confined space entry permit is good for the specific task and shift it was written for. Treat it as a single-use document, not a standing authorization. If the crew comes back the next day for more work in the same space, a new permit gets written with fresh atmospheric testing, even if nothing about the space appears to have changed. If conditions inside the space change mid-shift (a new odor, an equipment failure, an alarm), the entry supervisor cancels the permit on the spot and a new one is required before anyone re-enters.

Here is the structure of the permit itself, if you'd rather copy it directly:
| Field | Entry |
|---|---|
| Space identification / location | ____________________ |
| Purpose of entry | ____________________ |
| Date and authorized time period (this shift only) | ____________________ |
| Authorized entrants (names) | ____________________ |
| Attendant (name) | ____________________ |
| Entry supervisor (name, signature) | ____________________ |
| Hazards identified | ☐ Atmospheric ☐ Engulfment ☐ Entrapment ☐ Other: ______ |
| Isolation methods completed (LOTO, blanking, disconnection) | ____________________ |
| Oxygen level (acceptable: 19.5%–23.5%) | ____________________ |
| Flammability / LEL reading (acceptable: below 10%) | ____________________ |
| Toxic gas reading(s) | ____________________ |
| Time of testing and tester's initials | ____________________ |
| Rescue/emergency service and how to summon | ____________________ |
| Communication method between attendant and entrants | ____________________ |
| Required equipment (PPE, monitor, comms, retrieval) | ____________________ |
| Additional permits required (e.g. hot work) | ____________________ |
| Permit canceled / entry complete (time, signature) | ____________________ |
Copy this into a document, print it, and keep it at the entry point for the duration of the work. That's a requirement of the standard, not just good practice. Pair it with the rest of your written compliance documentation so confined space entries aren't the one program living outside your regular paperwork.
Where Small Crews Actually Get Cited
The pattern I see most in pre-audit walkthroughs isn't a crew skipping the permit entirely. It's a permit that's mostly right but thin on the details an inspector checks first: no actual gas readings recorded (just a checkbox), an attendant listed by role instead of name, or a permit dated for the whole week instead of the single shift the work happened in. Any one of those turns a documented, compliant entry into a citable violation on paper, even if the entry itself was handled safely. Our lockout/tagout procedures guide covers the isolation step in more depth, since incomplete LOTO is the hazard most often tied to a confined space incident.
Safety Team Technologies tracks hazard identification and permit-based work alongside your regular toolbox talks and training records, so a confined space entry has the same dated, retrievable paper trail as everything else in your safety program instead of living on a clipboard in a truck.
Frequently Asked Questions
What is a confined space entry permit?
A written authorization required by 29 CFR 1910.146 before entry into a space with a known or potential atmospheric, engulfment, or entrapment hazard. It records hazard testing, isolation steps, authorized entrants, and rescue procedures.
Is a confined space entry permit required by OSHA?
Only for spaces that meet OSHA's definition of a permit-required confined space: limited entry/exit, not built for continuous occupancy, and containing a serious hazard. A non-permit confined space with no serious hazard doesn't require one.
Do all confined spaces need a permit?
No. Only permit-required confined spaces do. A space can be reclassified as non-permit once every hazard is permanently eliminated, but that reclassification has its own documentation requirement.
How do you complete a confined space entry permit?
The entry supervisor verifies isolation is complete, has the atmosphere tested with results recorded, confirms rescue and communication procedures, lists entrants and the attendant by name, and signs before entry begins.
Who can authorize a confined space entry permit?
The entry supervisor, a specific role under 1910.146, often the site foreman or supervisor on a small crew, provided they're trained to evaluate the conditions rather than just sign the form.
How long is a confined space entry permit valid?
For the specific task and shift it was written for. Treat it as one shift at most. Changed conditions or extended work require the permit to be canceled and a new one issued.
Confined space permits living on a clipboard that never makes it back to the office? Safety Team Technologies keeps your hazard identification, permit-based work, and training records in one dated, searchable place, so the next time someone asks for last month's entry permits, it's a download instead of a search through a truck.
