Covers OSHA 29 CFR 1910.146 • Permit System • Atmospheric Testing • Rescue Planning

Course Overview

A confined space is any area large enough to enter, with limited means of entry or exit, that is not designed for continuous occupancy. Data centers contain more of these spaces than most people realize: crawl spaces beneath raised access floors, underground cable vaults and manholes, cooling-tower basins and sumps, water-treatment vaults, and some battery room and electrical vault configurations can all meet the definition — and some meet the stricter definition of a permit-required confined space because they contain or could contain a serious hazard. This course covers how to recognize these spaces and the OSHA-required permit system that governs entry.

Learning Objectives

By the end of this course, participants will be able to:

1. Define a confined space and a permit-required confined space, and identify examples in a data center.
2. Explain the roles of entry supervisor, attendant, and authorized entrant.
3. Describe the permit system and required atmospheric testing sequence.
4. Identify hazards specific to data center confined spaces, including hydrogen gas in battery areas.
5. Explain rescue planning requirements and why non-entry rescue is preferred.

Who Must Take This Course

Any employee who enters, attends, supervises entry into, or works in an area near a permit-required confined space must understand this program. Only employees specifically trained and authorized for a given space may enter it — this course provides awareness-level and refresher content and does not by itself qualify someone as an authorized entrant, attendant, or entry supervisor for a specific space.
