California ICC UST Inspector Practice Exam

Which of the following is not considered a confined space?

1. Space not designed for continuous employee occupancy

2. Area with limited access

3. Area with limited ventilation

4. Really deep turbine sump

The correct answer is: Area with limited ventilation

A confined space is typically defined as an area that is not designed for continuous employee occupancy, has limited access, and may have limited ventilation. The key aspect of a confined space is that it must meet specific criteria, which often include restrictions on entry and exit, as well as potential hazards that could arise from the environment within the space. In this case, the option that is not considered a confined space is one that refers to an area with limited ventilation. While limited ventilation can be a characteristic of confined spaces, it alone does not determine whether a space is confined. Other factors, such as accessibility and design purpose (not intended for continuous occupancy), play a more vital role in the classification. The presence of limited ventilation may indicate an increased risk within a confined space but does not, by itself, define a space as confined. The other options encompass characteristics that contribute to the definition of a confined space. Spaces not designed for continuous employee occupancy generally indicate a temporary or infrequent work area, while limited access refers to entry and exit challenges. The mention of a really deep turbine sump also suggests a space that is confined due to physical dimensions, further emphasizing the importance of access limitations.
