    1 1/2 pounds PACKAGING The EPOS is folded and sealed inside a multi-laminate barrier pouch. There are two versions of the barrier pouch: one is a clear multi-laminate pouch and the second is an opaque multi- laminate pouch (as shown below). Both pouches have the same form fit and function. The barrier pouch is then packaged inside a rugged fabric carrying case.

    7%. PROTECTION FACTOR Users of the EPOS are not affected by carbon monoxide and the other toxic gases produced in a fire, nor do chemical fumes from the spill of hazardous materials affect them. Unlike a filter mask, which must clean the poisonous outside air to make it fit to breathe, the EPOS provides its own source of clean breathable air.

  • Page 12 The next step is to visually inspect the color of the Humidity Indicator. If the Humidity Indicator is Blue the Unit is serviceable.

  • Page 13: Thermal Properties

    Plastics and tar dripping onto the EPOS hoodshell will have no adverse effects below 200°C (392°F). Radiant Heat Flux The EPOS hoodshell can withstand radiant heat of 1.0 BTU/sq. ft. for up to 60 seconds. MATERIALS OF CONSTRUCTION Hood The hood is a multi-layer design of polyimide film and PFA film, which provides excellent resistance to most chemicals.
  • Page 14: Performance

    Duration of the EPOS is defined as when the oxygen inside the hood drops below 18% or the carbon dioxide level exceeds 7%. The user will know when the oxygen concentration has dropped below 18% because the hood will collapse and press on the user’s face.
  • Page 15: Epos Donning Procedure

    CAUTION: FAILURE TO REMOVE THE HOOD WHEN OXYGEN LEVELS DROP BELOW 18% MAY RESULT IN SUFFOCATION AND DEATH. The EPOS is an excellent aide in escape or rescue from a chemical spill (it is not meant as a replacement for HAZMAT suits for cleaning spills) because of the self contained breathable clean air, and because of the high resistance of the hood to most chemicals.
