Which of the following describes the environment of a confined space?

A confined space is characterized primarily by having limited means of entry and exit. This specific condition creates unique challenges and hazards for workers who may need to enter these spaces. The lack of easy access can hinder rescue efforts in emergencies and requires proper planning and protocols to ensure safety during entry and work within the space.

In contrast, spaces designed for continuous worker occupancy typically have multiple exit points and are constructed to facilitate easy access and egress, which is not the case in confined spaces. Similarly, the environment does not allow for an unrestricted flow of personnel; rather, access is often restricted or controlled due to safety considerations. Additionally, many confined spaces do not have adequate natural airflow, making it vital to monitor and manage air quality effectively.
