Which of the following is NOT a characteristic of confined spaces?

The characteristic that indicates a space is not designed for continuous human occupancy is critical when defining confined spaces. Confined spaces are typically areas that are not meant for continual human presence; they may be entered for specific tasks, maintenance, or inspections but are generally intended for temporary access.

These spaces often have limited means of entry and exit, making them more hazardous, as individuals may find it difficult to escape in an emergency. They are also usually enclosed by bulkheads, which contributes to the confined nature, and they frequently present risks such as a potential for a hazardous atmosphere due to the accumulation of toxic gases or lack of oxygen.

By understanding that confined spaces are not designed for continuous occupancy, one can better address safety protocols and measures necessary for working in such environments. Therefore, recognizing that option C refers to a trait not applicable to confined spaces is essential for evaluating conditions where safety precautions must be meticulously followed.
