eTraining’s Confined Space Training is an OSHA-compliant online course developed under OSHA’s Permit-Required Confined Spaces standard 29 CFR 1910.146.

Confined spaces kill approximately 90 workers every year in the United States and seriously injure hundreds more, often because workers and rescuers are not properly trained to identify and control confined space hazards. A confined space is any area large enough to enter, with limited or restricted means of entry or exit, and not designed for continuous occupancy, including tanks, silos, vaults, manholes, pits, pipelines, and process vessels.

This 2-hour online course covers confined space identification, atmospheric hazards (oxygen deficiency, toxic gases, flammable vapors), physical hazards (engulfment, entrapment), permit-required entry procedures, personnel responsibilities (entrant, attendant, supervisor, rescue), equipment requirements, and emergency response.

Upon completion with a passing score of 70%, participants receive a personalized certificate. The course is divided into 4 units covering identification, hazards, personnel responsibilities, and equipment/procedures.

Frequently Asked Questions

Everything you need to know about the Confined Space Training.

Confined space training teaches workers to recognize confined spaces, understand the hazards present (atmospheric, physical, engulfment), and follow safe entry procedures per OSHA standards. A confined space is any area large enough to enter, with limited or restricted means of entry or exit, and not designed for continuous occupancy. Examples include tanks, silos, vaults, manholes, pits, pipelines, and tunnels. Training covers confined space identification, hazard assessment, permit-required entry procedures, roles and responsibilities of entry personnel, and emergency response protocols.

OSHA requires confined space training for any worker who enters or works around permit-required confined spaces, as set out in 29 CFR 1910.146 for general industry and 29 CFR 1926 Subpart AA for construction. This covers maintenance workers, tank cleaners, utility workers, construction crews, HVAC technicians, welders, pipeline workers, wastewater plant operators, firefighters, and anyone entering spaces such as storage tanks, silos, vats, pits, manholes, and tunnels. Importantly, it's not only the person going inside who needs training: attendants, who stay outside to monitor entrants and summon rescue, must be trained too, and so must entry supervisors who authorize and oversee the work. Employers are responsible for ensuring every worker involved in an entry understands the hazards and their specific role before work begins. This course satisfies that knowledge-based training requirement.

eTraining’s Confined Space Training takes approximately 2 hours to complete online. The course covers both general industry (29 CFR 1910.146) and construction (29 CFR 1926 Subpart AA) requirements. It is self-paced, so you can pause and resume on the same device at any time.
The three main categories of confined space hazards are atmospheric, physical, and environmental. Atmospheric hazards are the leading cause of confined space deaths and include oxygen deficiency (below 19.5%) or enrichment (above 23.5%), toxic gases such as carbon monoxide and hydrogen sulfide, and flammable vapors. Physical hazards include engulfment by stored materials like grain or sand, entrapment by converging walls or sloping floors, moving machinery, and electrical hazards. Environmental hazards cover extreme heat, excessive noise, limited visibility, and flooding. Under OSHA's 29 CFR 1910.146, the atmosphere must be tested before entry — first for oxygen, then combustible gases, then toxic gases — because these hazards are often invisible and odorless. Recognizing all three categories is the foundation of safe confined-space entry, and it's a core focus of this training course.
A confined space meets three criteria: it is large enough for a worker to enter and perform work, it has limited or restricted means of entry or exit, and it is not designed for continuous occupancy. Examples include tanks, silos, vaults, manholes, and pits. A permit-required confined space meets all three of those criteria plus one or more added hazards: it contains or may contain a hazardous atmosphere, contains material that could engulf an entrant, has converging walls or a sloping floor that could trap someone, or contains any other recognized serious safety or health hazard. Under OSHA's 29 CFR 1910.146, permit-required spaces demand a written entry permit, atmospheric testing, an attendant stationed outside, and designated entry personnel. Appendix A of the standard provides a decision flow chart to help employers classify each space correctly.
A confined space entry permit is a written document required by OSHA before workers enter a permit-required confined space. It must include: the space to be entered, purpose of entry, date and authorized duration, authorized entrants and attendants, name of entry supervisor, hazards identified, measures to control hazards, atmospheric testing results, rescue and emergency procedures, and communication procedures. The permit must be posted at the entry point.
A confined space entry team consists of four key roles: (1) Entry Supervisor – authorizes entry, verifies precautions, and terminates entry if needed; (2) Authorized Entrant – the worker who enters the confined space; (3) Attendant – remains outside the space to monitor entrants, maintain communication, and summon rescue if needed; (4) Rescue Personnel – trained and equipped to perform rescue operations if an emergency occurs. Each role has specific pre-entry, entry, and post-entry responsibilities.
OSHA's Permit-Required Confined Spaces standard for general industry is 29 CFR 1910.146, published in 1993 and still the governing rule today. For construction work, the standard is 29 CFR 1926 Subpart AA, which OSHA added in 2015 to give construction crews confined-space protections comparable to general industry. Both standards require employers to evaluate the workplace and identify confined spaces, assess the hazards present, implement written permit-entry procedures, provide worker training, and establish rescue capabilities before anyone enters. The full regulatory text is published in the eCFR (29 CFR 1910.146). eTraining's course covers the knowledge-based requirements from both standards, so it applies whether your work falls under general industry or construction. State requirements can differ, so always confirm your local rules before relying on any single course.
