A confined space is characterized by its design and use, not necessarily meant for continuous occupancy. Typically, a confined space is defined as an area that is not intended for human occupancy, has limited means of entry and exit, and may pose hazards. This means that spaces such as storage tanks, silos, or ventilation ducts fit the definition of a confined space because they are usually entered only for maintenance or inspection, not for continuous living or working.

The reasoning behind this classification emphasizes safety and the potential risks associated with entering such spaces, such as toxic atmospheres or insufficient oxygen levels. Because a confined space is not designed for continuous occupancy and is often accessed intermittently for specific tasks, the statement that it is defined as one designed for continuous occupancy is incorrect.
