Confined Space Awareness Training | What Every Employee Needs to Know (OSHA 1910.146)

This video provides Confined Space Awareness training for general employees who work near confined spaces but do not enter them, act as attendants, or supervise entries. This training explains what a confined space is under OSHA's Permit-Required Confined Spaces standard, why these spaces are so frequently fatal, and what every non-entry employee is responsible for when they encounter one. The training covers how to recognize a confined space and a permit-required confined space, the atmospheric and physical hazards that make them dangerous, and the four core rules every employee must follow around confined space entries in progress. This is not entrant, attendant, or supervisor training and does not teach atmospheric testing, rescue procedures, or permit system management. What's covered in this video: An explanation of OSHA's three-part definition of a confined space, requiring that a space be large enough to enter, have limited or restricted means of entry or exit, and not be designed for continuous human occupancy. Real-world examples of confined spaces employees may encounter, including storage tanks, silos, sewers, manholes, underground vaults, boilers, pipelines, and hoppers. The distinction between permit-required and non-permit confined spaces, and how permit spaces are identified through posted Danger Permit Required Confined Space signage. The atmospheric hazards that make confined spaces lethal, including low oxygen levels, toxic gases such as hydrogen sulfide and carbon monoxide, and flammable vapor buildup that cannot be seen, smelled, or felt. Physical hazards present in confined spaces, including engulfment from loose material such as grain or sand, mechanical hazards, structural collapse, and disorienting layouts that complicate escape. An explanation of why untrained rescue attempts are one of the deadliest mistakes in industrial safety, since a would-be rescuer can be overcome by the same hazard as the original victim within seconds. The first core rule of awareness training: never enter a confined space you are not specifically authorized to enter, even during an emergency. The second core rule: recognize and respect warning signs, barricades, caution tape, and posted attendants as absolute boundaries. The third core rule: know your facility's emergency alarm system, radio channel, or emergency contact procedure before an incident occurs. The fourth core rule: never move, disturb, or remove ventilation fans, air monitoring devices, or rescue tripods staged near an active entry. A walkthrough of what a properly conducted confined space entry looks like, including atmospheric testing, a posted written permit, staged rescue equipment, and a dedicated attendant maintaining constant communication with the entrant. Guidance on the role of the attendant and why their attention must remain fully focused on the entry without distraction from passing employees.
