BUENA PARK, Calif. (KABC) — An ammonia leak at a commercial building in Buena Park sent 13 people to hospitals Friday, but all were in stable condition and the leak was sealed.

According to the agency, Orange County Fire Authority firefighters responded to the hazardous materials situation just before 9:15 a.m. Friday in the 6500 block of Caballero Boulevard.

OCFA officials initially said 12 company employees were decontaminated and 11 were taken to hospitals. By day’s end, a total of 14 people had been treated and 13 taken to hospitals, all described as stable.

Late Friday evening, OCFA officials said the leaking material was clearly ammonia and the leak had been plugged. It was unclear what caused the leak.

On Saturday, firefighters said the cause of the release was an accident due to equipment striking an ammonia distribution line.
