Q: Do air handler mechanical rooms located at the top of a hospital, and are healthcare occupancies, require sprinkler systems?
A: Yes… if the rest of the hospital is required to be sprinklered. There is nothing in the code or standards that allows the air handler mechanical room to not be sprinklered when the rest of the hospital is required to be sprinklered. But, the mechanical room is not required to be sprinklered if the hospital itself is not required to be sprinklered. This is dependent on the date when the hospital was constructed; the date of the most recent renovation in the mechanical air handler room; the construction type; and any approved equivalencies you may have.
