How large must each area of refuge be to accommodate wheelchair spaces?

Each area of refuge must be sized to ensure accessibility for individuals in wheelchairs, allowing enough space for maneuverability while waiting for assistance or for rescue during an emergency situation. The correct dimensions for wheelchair spaces are 30 inches by 48 inches. This space is determined by guidelines that aim to provide a clear area for a wheelchair user to turn and position themselves safely, ensuring that they can access help without obstruction.

In contrast, the other sizes listed do not meet the minimum space requirements for adequate wheelchair accessibility. For example, while 24 inches by 36 inches may seem sufficient, it fails to provide the necessary turning radius and maneuvering space. Similarly, 36 inches by 60 inches and 42 inches by 72 inches offer more space but exceed the minimum requirement, which is why 30 inches by 48 inches is the most appropriate answer.
