A confined space is defined by a combination of specific characteristics that make it distinct from other types of spaces. It is indeed not meant for continuous employee occupancy, which emphasizes that it may not be safe or appropriate for employees to work in such spaces for prolonged periods without proper precautions or monitoring. Additionally, limited entry and exit are critical factors; these constraints can impede an employee's ability to leave the space quickly in an emergency, increasing risks related to safety.

Moreover, a confined space is large enough for an employee to enter and perform work, which highlights that while the space is characterized by limitations in movement and accessibility, it still permits physical entry and occupancy by personnel.

Thus, considering all these factors—non-continuous occupancy, limited means of entry and exit, and sufficient size for work—it is clear that the correct definition of a confined space encompasses all these elements. This comprehensive understanding emphasizes the importance of recognizing confined spaces in industrial and operational environments to adequately assess risks and ensure safety practices are in place.
