Describe the meaning of 'confined space'.

The definition of 'confined space' is specifically related to areas that are not designed for continuous occupancy and have limited means of entry and exit. These environments can pose significant health and safety risks due to factors like poor ventilation, potential for hazardous atmospheres, and physical space constraints that make it challenging for workers to enter and exit safely.

In a confined space, the conditions can vary widely and may include environments such as tanks, silos, or tunnels—any location that is not meant for prolonged use and where access may be restricted. This is why option C accurately describes a confined space; it highlights both the limitations in terms of access and the fact that such spaces are not intended for people to stay in continuously.

In contrast, wide, open areas or spaces designed for unrestricted work would not fit within the confines of this definition since they lack the inherent safety hazards and access restrictions typically associated with confined spaces. A location for tool storage does not address the characteristics related to occupancy or safety risks present in confined spaces.
