Permit-Required Confined Spaces — Regulatory crosswalk
Permit-Required Confined Spaces · v1.0.0 · October 22, 2026
Course developed by Todd Jerome Jenkins, MS, CSP.
General-industry knowledge course for 1910.146. Construction is separate. Actual site evaluation, role proficiency and rescue preparation remain employer work.
| Area | Basis | Lessons | Treatment and separate evidence |
|---|---|---|---|
| Recognize a permit space | 1910.146(a), (b), (c)(1)–(4) | recognize | Distinguish a confined space from a permit-required confined space. Locate the actual space inventory and explain the entry boundary without crossing it. |
| Understand the hazards | 1910.146(b), (d)(2)–(3), (h)(1), (i)(1)–(2), (j)(1) | hazards | Recognize atmospheric and physical hazards before entry. Review the specific hazards and warning signs for the assigned space and task. |
| Prepare controls and equipment | 1910.146(b), (d)(1)–(4), (d)(6)–(10) | controls | Explain what must be in place before entry is authorized. With the trainer, match each actual hazard to its control and show how readiness is verified. |
| Test and monitor the atmosphere | 1910.146(d)(5); Appendix B atmospheric-testing guidance | testing | Explain testing order, equipment limits and worker participation. Have the trainer demonstrate the actual monitor, checks, sampling plan, alarm response and recording method. |
| Read and use the entry permit | 1910.146(e), (f) | permit | Identify the permit information and authorization needed for entry. Use the permit-review worksheet with an actual completed permit; resolve missing information before entry. |
| Perform the authorized entrant’s duties | 1910.146(h) | entrant | Recognize entrant responsibilities for equipment, communication and exit. Explain and safely rehearse the site’s communication and exit actions without entering an uncontrolled space. |
| Perform the attendant’s duties | 1910.146(d)(6)–(7), (i) | attendant | Maintain entrant protection without distraction or unauthorized rescue entry. Practice entrant tracking, warnings, evacuation and the actual rescue call with the trainer in a safe simulation. |
| Perform the entry supervisor’s duties | 1910.146(j); (e)(5) | supervisor | Verify entry readiness and maintain control through handover and closure. Walk through a supervisor handover and identify what evidence would prevent authorization. |
| Plan rescue before entry | 1910.146(d)(9), (k); nonmandatory Appendix F | rescue | Explain rescue-service evaluation and non-entry retrieval requirements. Review the evaluated service, contact method, retrieval arrangement and safe practice evidence for the actual space. |
| Distinguish alternate entry and reclassification | 1910.146(c)(5)–(7) | alternatives | Explain why ventilation control is not hazard elimination. Ask the employer to explain the documented basis for any alternative; do not infer it from a fan or a clean reading. |
| Coordinate employers and learn from entries | 1910.146(c)(8)–(9), (d)(11)–(14), (e)(6), (l) | coordination | Explain contractor coordination, permit retention and program review. Identify the host and contractor contacts, change-notification method and location of canceled permits. |
| Verify training and workplace proficiency | 1910.146(g), (k)(2) | training | Identify training triggers, certification records and remaining practical requirements. Use the training record to document actual role instruction, observed proficiency, corrections and training triggers. |
