103 CMR, § 423.14
To maximize out-of-cell activities, the Superintendent or designee at each facility with a Restrictive Housing Unit shall assess whether, and to what extent, out-of-cell activities over and above five hours per week of out-of-cell recreation time (i.e., one hour per day, five days a week) per inmate are consistent with the safety and security of all staff and inmates in that Restrictive Housing Unit. Such additional out-of-cell activities may include, but not be limited to, additional recreation periods, longer recreational periods, or programming.
In assessing whether additional out-of-cell activities or programs can safely be offered, the Superintendent or designee shall consider any factors deemed pertinent to such assessment, including but not limited to, the number of inmates in the Restrictive Housing Unit, the number of available correction officers, the number of available program staff, the availability of physical space in the Unit, the nature of the threat posed by particular inmates, and/or the climate of the Restrictive Housing Unit.
