What is a key characteristic of a confined space?

A key characteristic of a confined space is that it has limited or restricted means of entry or exit. This restriction is what typically defines a confined space and presents unique hazards for individuals who may need to enter.

In such spaces, even if the environment may not be inherently hazardous, the restricted access can make it difficult for workers to evacuate quickly in an emergency or receive assistance. This characteristic necessitates specific safety precautions and monitoring practices to protect the health and safety of personnel entering these areas.

While continuous occupancy, monitoring requirements, and electrical hazards can be important considerations in certain contexts, they are not definitive criteria for identifying a confined space. A confined space may not necessarily be designed for ongoing occupation, not always require monitoring, and may or may not contain electrical hazards; these aspects depend on the specific situation rather than the basic definition of a confined space itself.
