Gov. Rick Scott of Florida announced new rules on Saturday requiring nursing homes and assisted-living facilities in the state to have generators capable of maintaining comfortable temperatures for at least 96 hours in the event of a power loss.

The governor’s announcement came three days after eight residents of a nursing home in Hollywood, Fla., the Rehabilitation Center at Hollywood Hills, died when the home lost power to its cooling system in the wake of Hurricane Irma.

The public outcry over the episode has intensified after the home said that its staff, or people calling on their behalf, had contacted the governor himself, as well as the power utility and several county and state agencies, to get the problem resolved, to little avail.

Under the new rules, all of the state’s assisted-living facilities and nursing homes will have 60 days to obtain what the governor’s statement called “ample resources” that will “sustain operations and maintain comfortable temperatures” for at least four days after a power failure. Those resources, the statement said, include a generator and fuel.
