Which three characteristics define a confined space?

The characteristics that define a confined space emphasize the limitations on entry and exit, the space's dimensions relative to the tasks performed within, and its intended use. A confined space is inherently restricted, often making it challenging for workers to enter and exit quickly, which can be critical in emergencies. The space must be large enough to permit work to be conducted safely but is not designed for continuous human occupancy, ensuring that it serves a specific purpose without being a permanent workplace environment. This highlights potential safety risks associated with confined spaces, underlining the importance of proper training and protocols for anyone working within such environments.
