A late-night blaze gutted a building housing a laundry and linen supply company in East Farmingdale, Suffolk County police and fire officials said.

An East Farmingdale fire official told News 12 Long Island that two firefighters were transported to a hospital to be evaluated for high blood pressure.

Fire officials said that heavy equipment had been called in at 6:30 a.m. to clear out -- and possibly level -- the building, which officials said was "heavily damaged" and sustained structural collapse.

Volunteers from East Farmingdale, North Amityville, South Farmingdale and other departments battled the fire, officials said. Department chiefs were not immediately available for comment.

Fire officials said smoke from the fire briefly caused visibility problems on the nearby Southern State Parkway, but that was not an issue for the morning commute.
