Which of the following best describes confined spaces?

Confined spaces are defined as areas that have limited means of entry and exit, are not designed for continuous occupancy, and may pose various hazards to individuals who enter them. This definition encapsulates environments such as tanks, silos, and manholes where workers can be exposed to dangerous conditions such as toxic gases, low oxygen levels, or engulfment risks.

In contrast, environments with extensive ventilation, designed for continuous occupancy, or highly accessible work zones do not fit the criteria for confined spaces. These characteristics typically allow for easier movement and better air quality, significantly reducing the risk associated with entering a confined space. Understanding these distinctions is vital for ensuring safety and compliance with OSHA regulations regarding confined space entry.
