In a multi-story office building, which of the following is considered a confined space?

In the context of a multi-story office building, an elevator shaft is classified as a confined space because it is enclosed and typically has limited means of entry or exit. Confined spaces are defined by their restrictive access, which can pose hazards, particularly in emergency situations. The unique structure of an elevator shaft limits airflow and can isolate anyone inside, making it critical to recognize this environment during safety assessments and emergency planning.

Conversely, an office cubicle, break room, and emergency exit do not meet the criteria for confined spaces. An office cubicle is open and accessible, enabling easy exit and movement. A break room serves as a communal area with ample space and no restriction on entry or egress. An emergency exit is designed specifically for safe egress during emergencies and typically provides unobstructed access, further distinguishing it from the characteristics of confined spaces. Understanding these distinctions is essential for ensuring safety and proper practices in commercial settings.
