OCALA, Fla. (AP) — Authorities say an apparent spark within the high-oxygen chamber of a Florida equine sports medicine center triggered a massive explosion, collapsing a corner of the building and killing a worker and a horse.
The Marion County Sheriff's office said 28-year-old Erica Marshall died in the Friday explosion at Kesmarc Farm and Equine Rehabilitation Center in Ocala. A second worker was taken to a Gainesville hospital with serious injuries.
Authorities say the workers were in a hyperbaric chamber with the horse as part of the animal's rehabilitation. Officials say it is not clear what caused the spark.
The center opened in 2009 to aid the recovery and conditioning of horses.
