What does "dry cell" mean in correctional facilities?

A "dry cell" in correctional facilities refers specifically to a cell that does not have water available for inmates. This designation is often used as a precautionary measure, particularly when dealing with inmates who may be suspected of concealing contraband or illicit substances within their bodies. By placing an inmate in a dry cell, correctional staff can monitor and prevent the ingestion of water, which might assist in flushing out these substances.

This practice helps to ensure the safety and security of the facility by minimizing the risks associated with contraband. The other options, while they refer to different types of cells or conditions that may exist within a correctional environment, do not describe the specific function and purpose of a dry cell in relation to inmate management and safety protocols.
