Which of the following characterizes a confined space?

A confined space is typically characterized by limitations on access and egress. This means that the entry and exit to the area are restrictive, making it challenging for workers to enter or exit quickly in case of an emergency. Such limitations may result from physical barriers, the shape of the space, or the location of the entry points. Understanding this characteristic is crucial for safety protocols, as confined spaces can pose significant hazards, including the accumulation of toxic gases or the risk of engulfment.

High ventilation is not a defining feature of a confined space; in fact, many confined spaces may have poor ventilation, which can lead to dangerous atmospheres. Continuous monitoring is essential in the context of safety procedures for confined spaces, but it is not a characteristic of the space itself, rather it serves to ensure safety while working in such conditions. Wide openings for entry typically describe areas that are not confined, as confined spaces often have limited openings that contribute to their classification.
