Confined spaces can present severe safety hazards to the people working in them. To address these risks, OSHA created standards to make sure workers can get in and out safely, and do their jobs without endangering their health.
Companies have a responsibility to inform their workers and subcontractors about safety practices when working in confined spaces. OSHA Standard 1926 Subpart AA requires special training for workers who must enter and/or supervise a confined space where a physical or atmospheric hazard exists, or is reasonably likely to develop, that could interfere with a worker’s ability to exit the space.
