What defines a confined space?

A confined space is specifically characterized by its physical limitations and its intended use. It must be large enough for a person to enter and perform assigned work, which aligns with the requirement that it is large enough to facilitate entry. However, it possesses restricted means of entry and exit, making escape in an emergency situation potentially challenging.

Additionally, a key aspect of a confined space is that it is not designed for continuous occupancy. This means it is typically a space where individuals do not remain for extended periods; rather, they enter to perform specific tasks. This definition is crucial in the context of safety regulations and standards, as confined spaces can present various hazards, including inadequate ventilation, toxic atmosphere, or the presence of moving equipment, thereby necessitating strict safety protocols when entering and working in such environments.

The other options do not align with this definition. Continuous occupancy suggests a different type of environment, usually designed with features for regular human use. Large openings imply ease of access, which contradicts the concept of confinement, while an outdoor area typically does not fit the conditions required to be classified as a confined space.
