3M™ Scott™ Flite COV (Change Over Valve) is a positive pressure supplied air respirator that also provides emergency respiratory protection and escape capability allowing the user to enter hazardous atmospheres including those identified as Immediately Dangerous to Life or Health (IDLH). If needed, the switch to the emergency air supply cylinder is accomplished by an automatic changeover valve requiring no user intervention if the airline supply fails and the user needs to exit using the escape cylinder. The unit also features a flame retardant polyester harness with stainless steel buckles, combined cylinder and pressure reducing valve assembly and a rugged mask-mounted demand valve with automatic first breath activation. The Flite COV can be used in applications such as confined space entry, hazardous materials handling and many general maintenance tasks in a variety of industries including chemical, petrochemical, oil and gas and public utilities.
