What is the size range for a confined space?

A confined space is defined by particular characteristics rather than a strict size limitation. This definition allows for a wide range of dimensions, making the answer that a confined space can be as large as a tank, vessel, or silo accurate. Confined spaces have the potential to be large areas that are not intended for continuous occupancy and have limited means of entry and exit.

For instance, tanks and silos can be quite large but may still fit within the criteria of a confined space due to their restrictive access and potential hazards present within. Understanding this concept encourages awareness of safety protocols needed for working in various environments, whether small or large, where people could be at risk.
