Confined Space Entry Permit Template (OSHA 1910.146 Compliant)

Quick answer: Every entry into a permit-required confined space needs a written entry permit signed before work begins. This guide covers exactly what OSHA 29 CFR 1910.146 (general industry) and 1926.1204 (construction) require on your permit — and where to get a compliant template.

Why Confined Space Kills More Workers Than It Should

Confined space fatalities have a horrible pattern: 60% of the deaths are would-be rescuers who entered without protection to help the first victim. Written permits and rescue plans exist specifically to prevent this cascade.

OSHA takes confined space seriously. When something goes wrong, the citation is often willful — because the standard has been on the books since 1993 and everyone knows the rules.

The 3 Elements That Make A Space "Permit-Required"

Under 1910.146(b), a confined space needs all 3 general traits:

Large enough to enter and perform work
Limited or restricted means of entry/exit
Not designed for continuous occupancy

Then it becomes PERMIT-REQUIRED if it also has:

Hazardous atmosphere (flammable, toxic, oxygen-deficient below 19.5% or enriched above 23.5%)
Material that could engulf an entrant
Configuration that could trap or asphyxiate (converging walls, sloped floors)
Any other recognized serious safety or health hazard

What Must Be On A Confined Space Entry Permit

Under 1910.146(f), the permit must document:

Space Identification

Specific location and description
Purpose of entry (inspection, cleaning, repair, etc.)
Date and duration of entry

Authorized Personnel

Entry supervisor (signature)
Authorized entrants (names)
Attendants (names)
Rescue service contact

Hazards And Controls

Identified hazards
Isolation procedures completed (LOTO, blanking, blinding)
Ventilation type and equipment
Atmospheric testing results (oxygen, LEL, toxic gases)
PPE and rescue equipment required

Communication

Method (radio, direct visual, tap signal, etc.)
Rescue procedure summary
Contact numbers

Atmospheric Testing

Must be done in this order:

Oxygen (19.5-23.5% acceptable)
Combustible gases (<10% LEL)
Toxic gases (below PEL)

Retest at intervals appropriate to the operation. If conditions change, retest and re-permit.

Common Confined Space Mistakes That Kill

No pre-entry atmospheric test — Or the test was done from outside, not inside the space.
Untrained attendants — Attendant left post to "help" and became second victim.
No rescue plan — "Call 911" is not a rescue plan. Fire department average response is 6-14 minutes. That's brain death in an oxygen-deficient atmosphere.
Bypassed lockout/tagout — Line reactivated by someone unaware entry was happening.
Old permit reused — Conditions changed since morning testing; new hazards not caught.

The Rescue Plan Requirement

1910.146(k) requires a written rescue procedure. Options:

1. In-House Rescue Team

Employer trains and equips its own rescue team. Requires annual practice in the actual space, medical monitoring, and full PPE including SCBA. Expensive but fastest response.

2. Contracted Rescue Service

Third-party emergency response contract. They must be evaluated for capability and response time. Local fire department may qualify ONLY if they have proper training and equipment specific to your spaces.

3. Non-Entry Rescue

Retrieval system (harness + retrieval line to mechanical device) that can extract an entrant without another person entering. Best option when feasible. Cannot be used if entrant is entangled or unconscious in an obstructed space.

Frequently Asked Questions

What qualifies as a permit-required confined space?

Under 29 CFR 1910.146, a permit-required confined space (PRCS) has all three general characteristics of a confined space (large enough to enter, limited entry/exit, not designed for continuous occupancy) PLUS one or more of: hazardous atmosphere, engulfment potential, converging walls or downward sloping floor, or any other recognized serious safety hazard. Examples: manholes, tanks, vaults, silos, some vessels.

When is a written entry permit required?

For every entry into a permit-required confined space. The permit must be completed before entry, signed by the entry supervisor, and posted at the site. It documents pre-entry atmospheric testing, ventilation, communication method, rescue plan, and authorized personnel.

Who fills out the confined space entry permit?

The entry supervisor is responsible. But atmospheric testing must be done by a qualified person with a calibrated meter. Attendants and entrants have their own duties documented on the permit. All four roles (entry supervisor, attendant, entrant, and rescue) must be identified.

How long is a confined space permit valid?

One shift maximum. If work continues into a new shift, a new permit must be issued. Also, if any condition changes during the entry (atmosphere reading changes, an entrant exits and returns, rescue equipment is disturbed), a re-evaluation and new permit is required.

What are the OSHA fines for confined space violations?

2026 penalties: Serious violation up to $16,550 per instance. Willful/repeat up to $165,514. Confined space consistently ranks in OSHA's Top 15 most-cited standards, and fatalities in confined spaces are almost always cited as willful due to the well-known hazards.
