Fire Saturday night destroyed the third floor of the private Hospital Cooperativo San Carlos Borromeo in Ciudad Quesada.
There were no injuries reported, but the blaze gutted administrative offices, an ophthalmology section and other areas with expensive medical equipment.
Firemen got the call about 6:26 p.m. The first truck was at the scene four minutes later, and eventually units came from Pital and Zarcero as well as Ciudad Quesada.
Fire officials said they were successful in keeping the flames from reaching a pharmacy on the second floor. Firemen also had to remove some oxygen tanks from the scene to avoid an explosion.
Fire officials said that on arrival they began a search of the structure to see if there were any individuals still inside. Then they attacked the fire, which had made headway.
The entire third floor was spouting flames at the height of the blaze.
The private hospital is near the public hospital in the community.
