The Dräger PSS® Rescue Hood is a constant flow emergency escape hood which allows for safe and uncomplicated escape from hazardous environments. The small light weight design allows a fire fighter to move without encumbrance. The unit is quick and easy to activate by simply placing over the head of the person to be rescued and connecting to the secondary supply hose connection. The hood is fixed in place by a simple draw string around the neck and a constant stream of air is released in to the hood.
