Frequently Asked Questions

Everything you need to know about the Confined Space in Construction.

Confined space in construction training is a safety education program that teaches construction workers how to recognize, enter, and work safely in and around confined spaces. eTraining’s course provides approximately 2 hours of instruction covering OSHA 29 CFR 1926 Subpart AA standards, including confined space identification, permit-required vs. non-permit confined spaces, atmospheric hazards, ventilation, entry permits, roles and responsibilities of entrants, attendants, and entry supervisors, and rescue planning. Upon completion, participants receive a printable certificate of completion.
OSHA 29 CFR 1926 Subpart AA requires employers to train all construction workers who enter or work in and around confined spaces. Training must cover the hazards of confined spaces, proper entry procedures, and emergency response. This applies to workers who physically enter confined spaces as well as attendants who monitor entries from outside. Employers must ensure workers are trained before they enter any confined space on a construction site.
The course takes approximately 2 hours to complete. Because it is self-paced, you can complete it over multiple sessions at your convenience. Most students finish within 1 week. You have 6 months from your enrollment date to complete all coursework. Progress is saved automatically on the same device, so you can stop and resume at any time.
A non-permit confined space meets the basic definition of a confined space (large enough to enter, limited entry/exit, not designed for continuous occupancy) but does not contain hazardous conditions. A permit-required confined space has one or more additional hazards: a hazardous atmosphere, material that could engulf an entrant, inwardly converging walls or floors that could trap an entrant, or any other recognized serious safety or health hazard. Permit-required spaces require a written entry permit, atmospheric monitoring, an attendant, and a rescue plan before entry.
The course covers: definitions and identification of confined spaces on construction sites; permit-required vs. non-permit confined spaces; atmospheric hazards including oxygen deficiency, flammable gases, and toxic substances; physical hazards including engulfment, entrapment, and electrical; atmospheric monitoring and ventilation requirements; entry permit requirements and procedures; roles and responsibilities of entrants, attendants, and entry supervisors; rescue planning and emergency procedures; and reclassification of permit-required spaces. The course includes quizzes throughout to reinforce learning.
You must score at least 70% on the final exam to pass and receive your certificate of completion. The course includes knowledge-check quizzes throughout to help prepare you for the final exam. If you do not pass on your first attempt, you can retake the exam.
