Course Overview

Protect Yourself and Your Crew in Confined Spaces

Confined spaces on construction sites, including manholes, tanks, pits, sewers, vaults, and other enclosed areas, present serious atmospheric and physical hazards. Workers have died from oxygen deficiency, toxic gases, engulfment, and other dangers that can develop quickly in spaces not designed for continuous occupancy.

This 8-hour online training course teaches construction workers the federal OSHA requirements for safe confined space entry under 29 CFR 1926 Subpart AA. You'll learn how to recognize permit-required confined spaces, understand the three critical roles in entry operations (authorized entrant, attendant, and entry supervisor), identify atmospheric and physical hazards, and follow the procedures that keep you and your team safe.

Confined Space Identification

Learn to distinguish confined spaces from permit-required confined spaces, recognize common construction examples like manholes and trenches, and understand what makes a space hazardous enough to require a permit.

Atmospheric and Physical Hazards

Understand oxygen deficiency and enrichment, flammable gases and combustible dust, toxic substances and IDLH conditions, engulfment hazards, and dangerous configurations or energy sources.

Your Role and Responsibilities

Master the specific duties of authorized entrants, attendants, and entry supervisors, including communication requirements, atmospheric monitoring, emergency exit conditions, and rescue procedures.

Safe Entry Procedures

Know how atmospheric testing is performed, what constitutes acceptable entry conditions, how hazards are controlled through isolation and ventilation, and how entry permits authorize and document safe operations.
