Define "confined space" in a safety context.

In a safety context, the definition of "confined space" is a space that is not designed for continuous occupancy and has limited means of entry or exit. This definition is critical because it emphasizes the potential hazards associated with working in such environments. Confined spaces can present significant risks, including poor ventilation, the presence of hazardous materials, or the risk of entrapment.

The criteria for a confined space highlight the importance of recognizing these work environments in order to implement appropriate safety measures and procedures. These spaces are often encountered in industries like construction, manufacturing, and utilities, where workers may need to enter tanks, silos, or underground vaults that meet the defined characteristics. Understanding this definition helps ensure that proper safety protocols, such as atmosphere testing and rescue plans, are in place before any work begins.
