What defines a confined space?

A confined space is characterized as a small or restricted area that is not designed for continuous human occupancy. This definition highlights the limitations of movement and accessibility within the space, which can pose safety risks for individuals who must work in such environments. Confined spaces often have entry and exit restrictions, which can create hazards like poor ventilation, accumulation of toxic gases, or the potential for entrapment.

The other options present characteristics that do not align with the definition of a confined space. These options describe areas that are either designed for human use, have ample access and egress, or are spacious enough for maintenance work, none of which fall under the category of confined spaces. Understanding this distinction is crucial for identifying potential hazards and ensuring proper safety protocols are in place when working in or around confined spaces.
