What constitutes a confined space according to OSHA?

Confined spaces are defined by OSHA based on several key characteristics, and all the identified aspects must be present for a space to be classified as such. A confined space is first defined by its limited means of entry and exit, which can make it challenging for workers to enter or leave safely. Additionally, a confined space is not intended for continuous occupancy, meaning that it is not designed for people to remain in for extended periods. Lastly, the presence of a potential hazardous atmosphere, such as toxic gases, dusts, or insufficient oxygen levels, is crucial as it highlights the inherent risks associated with working in such spaces.

When all these factors are combined, they create a situation that necessitates strict safety protocols and precautions to protect workers who may find themselves in such environments. Therefore, the correct classification of a confined space incorporates all these elements together, leading to the conclusion that all of the aforementioned aspects are required for determining whether a space is confined.
