 MSA Escape Cylinder PremAire System Upgrade Kit
The Premiere escape-cylinder option allows users to work in an IDLH (Immediately Dangerous to Life or Health) atmosphere by providing an emergency-escape capability.The National Instititute for Occupational Safety and Health (NIOSH) requires this capability for any supplied air respirator used in an IDLH atmosphere.
IDLH means conditions that pose immediate threat to life or health, or conditions that pose an immediate threat of severe exposure to contaminants, such as radioactive materials, which are likely to have adverse cumulative or delayed effects on health.
PremAire Respirators equipped with this option feature a belt-mounted, carbon fiber or aluminum air cylinder. In normal use, the apparatus operates on the same principle as the PremAire pressure demand supplied-air respirator. When connected to an air source,it provides continuous respiratory protection until the user disconnects from the air supply hose. In an emergency-escape situation, the cylinder portion of the apparatus is activated by opening the cylinder valve. Should the primary air supply fail or be interrupted, the cylinder provides an emergency source of air for escape from the dangerous atmosphere.
Depending on user needs,escape cylinders are available in either a five- or ten-minute-rated air supply. Depending on user preference,wearers also have a choice of cylinder placement - positioned on either the left or right hip.
Note: The emergency-escape air cylinder is the only PremAire Respirator configuration approved for use in IDLH conditions.
