N.Y. Comp. Codes R. & Regs. tit. 14, § 595.16
(b) Subsequent to admission:
(1) For service enriched single room occupancy and congregate programs, timed drills should be used to regularly evaluate the level of evacuation capability of program residents. Translation of drill times to evacuation capability may be determined as: Evacuation capability is based on the time of day or night when evacuation of the facility would be the most difficult (i.e., sleeping residents or fewer staff present). Residents needing assistance in evacuating should be assisted by staff to the extent that assistance would be available at the time of day or night in an actual emergency.
(d) Residents and prospective residents shall only reside in or be admitted to a type of residential program appropriate to the individual's evacuation capability.
