The Emergency Passenger Oxygen System (EPOS) is a self-contained protective breathing device intended for trained individuals in military aircraft emergencies such as decompression, fire, evacuation, rescue, smoke-filled cabins, toxic fumes or hazardous cargo spills.  The EPOS utilizes compressed aviator grade oxygen and CO2 scrubbers to furnish up to 60 minutes of oxygen for someone at rest.  The patented hood provides 360° visibility and dons in less than 15 seconds.  This smokehood is used by the USAF and other air forces around the world.
