    Hyperbaric Chamber Explosion

    I was gifted to be able to attend last years' Benefit for the Catalina Chamber, courtesy of the gracious sponsorship of Tobin George. As a former hyperbaric Chamber operator, this hits especially home.

    It is with great sadness that I report an explosion of a Hyperbaric Chamber in Ocala, FL, which killed the inside chamber tender and the patient (a horse).

    Woman, Horse Dead after Hyperbaric Chamber Explosion


    by: Pat
    Raia
    February 10 2012, Article # 19591

    While Florida fire authorities probe the cause of a hyperbaric oxygen chamber
    explosion that killed one horse and one woman and injured another woman, an
    equine veterinarian who founded a hyberbaric-oxygen-therapy-focused veterinary
    society said practitioners strive to minimize risk associated with the
    technology.

    According to published reports, on Feb. 10, a hyperbaric oxygen chamber
    exploded at the Kentucky Equine Sports Medicine and Rehabilitation Center
    (KESMARC) in Ocala, Fla., when a horse inside the chamber began kicking. The
    horse and a woman were killed in the incident. Another woman sustained
    injuries, the reports said. Marion County, Fla., fire rescue officials are
    investigating the cause of the incident. A representative from KESMARC Florida
    was unavailable for comment.

    Hyperbaric oxygen therapy (HBOT) involves treating a patient
    with 100% oxygen under pressure; veterinarians have explained the process
    increases oxygen levels in blood plasma and promotes higher delivery to all
    body tissues, including the injured area, to facilitate healing. In horses HBOT
    is used to treat a range of conditions and acute injuries, including deep
    wounds, joint injuries, and infections. Horses treated with HBOT are placed in
    chambers that are approximately 10 to 12 feet in diameter.

    Dennis Geiser, DVM, Dipl. AVBP, associate professor in the Large Animal
    Clinical Sciences department at the University of Tennessee’s College of
    Veterinary Medicine and founder of the Veterinary Hyperbaric Medical Society,
    declined to comment specifically about the KESMARC Florida incident. But he
    said that HBOT chambers used in the United States are manufactured according to
    specific safety standards, and that practitioners take precautions to ensure
    horses’ safety during treatment.

    The cause of the explosion is unknown and currently under
    investigation.

    Geiser said that while the oxygen itself is unlikely to ignite, oxygen
    under pressure could be ignited in the presence of a spark.

    “So we don’t put shod horses in the chamber,” Geiser said of his approach
    to safety. “We take the shoes off if we can, or we put boots on the horse or
    otherwise cover its feet.”

    In addition, he said rubber material about halfway up the interior walls of
    some chambers to further minimize spark risk, he said. Geiser declined to
    speculate on whether the KESMARC Florida chamber contained the rubber wall
    material.

    Geiser said that the majority of hyperbaric oxygen chambers are
    manufactured by Veterinary Hyperbaric Oxygen, a Lexington, Ky.-based company.
    No one from the firm was available to comment on the KESMARC incident.

    I just don't log dives
    It's been a while since I have heard of a HBC explosion. Sad thing.

    I thought that race horses wore aluminum shoes.
    There was a young man of Dundoo
    Whose limericks stopped at line two.

    It was a horrible accident, and there are conflicting reports and confusion over reports. Some excerpts...

    From Manufacturer urges facilities to stop using hyperbaric chambers following explosion
    She said they allowed horses to wear shoes in the chamber, because she had always been told it was safe because of the rubber floors and padding on the walls.
    From Woman identified in fatal Marion County hyperbaric chamber explosion | News - Home
    Rhonda Stroup, a Marion sheriff detective, said the horse kicked off a protective shield inside of the oxygen-filled chamber and as the steel shoe as struck the side of chamber, it caused a spark and ignited instantly.
    From Woman, horse killed, 1 injured in Marion Co. hyperbaric... | www.wftv.com
    Equestrian experts said it's highly unusual to put horses inside the chambers without tranquilizing them first, but it's not required.

    WFTV was told that this could have been prevented if the horse had aluminum shoes because those are not magnetic and wouldn't have caused that spark.

    You can test the tanks you breathe or - dive on hope.
    Testing is safer...


    Great news for vacation divers who cannot talk themselves into buying a personal CO tank tester!

    Yeah it's just the air we breath - at depth!

    There's more to it then a spark from a horseshoe. Oxygen is not a fuel - it doesn't burn. It had to come into contact with a fuel to cause an explosion.

    I can understand the horse, as I almost had a claustrophobic panic attack on entering a small chamber on a dive ship. I closed my eyes and meditated through it and when the ventilation started fortunately the feeling went away.

    Perhaps they should have sedated the horse first.

    How much methane is in a horse fart?

    A little bit of Acetylene gas and Oxygen makes a boom that sound likes a cannon, I'll speculate that methane and O2 would be an explosive mixture.

    I think it was mentioned that they usually do, but this horse had been in before and seemed to behave well. I'd want it sedated.

    Enough to ignite a horse tail...?

    I had to chime in on this one, my other expencive hobby is as a horseback rider (the only thing in the world I may like even more then diving).

    Yes, there are lightweight shoes made of composite, aluminum, and even rubber like the bottom of a tennis shoe, and they do tend to use them on racehorses. However, Ocala is the winter sport horse mecca of the universe, so you're dealing with mostly high end jumping or other olympic dicipline horses at this time of year in that part of the world. Most horses still wear steel shoes because they can be re-worn many times, are less expencive, and don't require particular expertise to apply.

    Yes, the horse should have been sedated. Most performance horses are used to tight spaces, they go on long trailer rides regularly, so it would not be unheard of to take a horse that has always traveled calmly and trust him. Sedation always has it's risks, so it's always better to go without if at all possible. That said, **** happens with horses, they're more predictable then humans, but who knows... the handler could have moved abruptly causing the horse to become upset. We'll likely never 100% know.

    I've been wondering how they handle ear clearing with a horse?
