Who needs confined space training?

OSHA requires confined space training for all workers who enter or work around permit-required confined spaces. This includes maintenance workers, tank cleaners, utility workers, construction personnel, HVAC technicians, welders, pipeline workers, wastewater operators, firefighters, and anyone entering tanks, silos, vats, pits, manholes, and tunnels.

How long does confined space training take?

eTraining's Confined Space Training takes approximately 2 hours to complete online. The self-paced course covers both general industry and construction requirements and allows pausing and resuming on the same device.

Does confined space training expire?

OSHA does not set a specific expiration date for confined space training. However, retraining is required when job duties change, hazards change, or employer concerns arise. Annual refresher training is recommended as best practice.

What is a confined space entry permit?

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 location, entry purpose, date and duration, authorized personnel, hazards identified, control measures, atmospheric testing results, rescue procedures, and communication methods.

What is the OSHA standard for confined spaces?

OSHA's Permit-Required Confined Spaces standard for general industry is 29 CFR 1910.146. For construction, the standard is 29 CFR 1926 Subpart AA. Both require identifying spaces, evaluating hazards, implementing procedures, providing training, and establishing rescue capabilities.

Confined Space Entry Training & Certification

Q: What are the 3 main hazards of confined spaces?

The three main categories are: (1) Atmospheric hazards — oxygen deficiency (below 19.5%) or enrichment (above 23.5%), toxic gases (carbon monoxide, hydrogen sulfide), and flammable vapors; (2) Physical hazards — engulfment by stored materials, entrapment by converging walls, moving machinery, electrical hazards; (3) Environmental hazards.

Q: What are the roles in a confined space entry team?

The team consists of four 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.

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 all workers who enter or work around permit-required confined spaces. This includes maintenance workers, tank cleaners, utility workers, construction workers, HVAC technicians, welders, pipeline workers, wastewater plant operators, fire fighters, and anyone entering spaces like storage tanks, silos, vats, pits, manholes, and tunnels. Both entrants and attendants (workers who monitor from outside) must be trained.

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: (1) Atmospheric hazards – oxygen deficiency (below 19.5%) or enrichment (above 23.5%), toxic gases (carbon monoxide, hydrogen sulfide), and flammable vapors; (2) Physical hazards – engulfment by stored materials, entrapment by converging walls, moving machinery, electrical hazards; (3) Environmental hazards – extreme heat, noise, limited visibility, and flooding. Atmospheric hazards are the leading cause of confined space fatalities.

A confined space meets three criteria: large enough to enter, limited entry/exit, and not designed for continuous occupancy. A permit-required confined space has all these criteria PLUS one or more additional hazards: contains or may contain a hazardous atmosphere, contains material that could engulf an entrant, has converging walls or sloping floors that could trap someone, or contains any other recognized serious safety or health hazard. Permit-required spaces require a written entry permit, atmospheric testing, and designated entry personnel.

OSHA does not set a specific expiration date for confined space training. However, OSHA requires retraining when job duties change, confined space hazards change, the employer has reason to believe the worker’s knowledge is inadequate, or during a workplace audit. Many employers and safety professionals recommend annual confined space refresher training as a best practice.

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.

Yes. eTraining’s Confined Space Training is 100% online and covers all OSHA-required knowledge-based training topics, including hazard identification, permit procedures, personnel responsibilities, and emergency response. Employers may supplement online training with site-specific practical training on atmospheric monitoring equipment, PPE, and rescue procedures specific to their confined spaces.

OSHA’s Permit-Required Confined Spaces standard for general industry is 29 CFR 1910.146. For construction, the standard is 29 CFR 1926 Subpart AA. Both standards require employers to identify confined spaces, evaluate hazards, implement entry procedures, provide training, and establish rescue capabilities. eTraining’s course covers requirements from both standards.
