  • Oxygen Safety In Refuge Alternatives - Dated 11/20/2009
    A portable Refuge Alternative, Shelter, or Chamber will provide miners protection in the event of a mine emergency. The unit can sustain miners for 96 hours as they await rescue. In order to provide the 96 hours of breathable air for miners, the refuge alternatives are equipped with high-pressure compressed oxygen cylinders. The oxygen delivery system remains in a "ready state" until it is "deployed" by miners during a mine emergency.

  • Oxygen Safety - Dated 8/2003
    On Saturday, August 16, 2003, a 51-year-old mine rescue team benchman with 18 years of mine rescue experience, was seriously burned while filling SCBA cylinders with pure oxygen. The victim was preparing to fill the cylinders by opening a ball valve allowing oxygen from the supply tanks to enter a Haskel Oxygen Booster System designed for oxygen service. The oxygen in a filter and the piping supplying the pump ignited combustible material within theses components. The resulting fire burned through the filter and piping, engulfing the victim.
