PARAMUS, N.J. (CBSNewYork) – A sudden explosion rocked an animal hospital in New Jersey Friday.

“I was just driving up as the thing blew up … it’s an old MRI machine which was being dismantled as we speak and a new one installed,” hospital owner Dr. Coleman Palminteri told CBS2’s Christine Sloan.

The explosion caused a ceiling in a small room to collapse but none of the animals were hurt because they were in a different part of the building, Sloan reported.

Three outside contractors repairing the machine were hurt. One man is in critical condition, 1010 WINS’ Carol D’Auria reported.

“No animals or any of our staff were injured,” Palminteri said.

Four of the animals that had been in critical condition were rushed to other hospitals.

Other animals were evacuated to a nearby building and their owners rushed to the hospital.

“I am happy she’s all right,” said pet owner Joe Morocco of Weehawken.
