CWEA Mechanical Technologist II Practice Test

The definition of a confined space provided by CAL-OSHA is focused on the conditions that distinguish it from other types of spaces. A confined space is characterized by having limited or restricted means of entry and exit, even though it may be large enough to enter and perform work. This restriction can lead to potential hazards, such as difficulty in evacuating if an emergency arises or accumulation of hazardous atmospheres.

In contrast, spaces with unrestricted entry and exit, or those designed specifically for permanent human occupation, do not fall under the confined space category since the limitations in access and potential hazards that define confined spaces are absent. Additionally, the location in relation to ground level is not a defining factor; a confined space could exist at any elevation. Thus, it's the limited entry or exit that primarily qualifies a space as confined, making the provided answer accurate and aligned with CAL-OSHA's criteria.
