The state's Commission on Corrections is set to approve new rules for the treatment of prisoners held in jails around New York.

The new regulations will mandate all solitary prisoners get at least four hours outside their cell each day.

It will also require jail administrators to tell the state whenever a prisoner younger than eighteen is placed in solitary, or when an inmate is held in solitary for more than a month.

Governor Cuomo says the standards will create consistent rules and prevent prisoner mistreatment.

Solitary confinement has already been banned for young city inmates at Rikers Island.

Those rules took effect last fall.
