California ICC UST Inspector Practice Exam

When assessing confined spaces, which feature is NOT typically required?

1. Limited means of entry and exit

2. Design to allow for continuous occupancy

3. A space large enough for bodily entry

4. Control or monitoring of the atmosphere

The correct answer is: Design to allow for continuous occupancy

When assessing confined spaces, the feature that is not typically required is designed to allow for continuous occupancy. Confined spaces are defined primarily by their entry and exit conditions, size, and atmospheric considerations, rather than their suitability for continuous human occupancy. A confined space must have limited means of entering and exiting, which indicates accessibility challenges. It also needs to be large enough for a person to enter bodily, which is crucial for the safety of workers entering the space. Additionally, the control or monitoring of the atmosphere is essential in confined spaces because they can contain hazardous conditions that necessitate monitoring for toxic gases, oxygen levels, or other hazards. Conversely, while some confined spaces may be occupied for extended periods, this is not a requirement; many confined spaces are only designed for short-term access or tasks. Thus, the aspect of continuous occupancy is not a defining feature of confined spaces as established by safety regulations and standards.
