Donning the VRU+

The VRU+ donning steps are as follows:

Open pouch
Remove sealed VRU+
Tear open package
Remove VRU+
Hold the bottle and activate the oxygen flow
Put hands in neck seal
Pull the VRU+ over your head

Operation

The VRU+ is a closed circuit rebreather system. Oxygen flows into the hood and is breathed and rebreathed by the user. The oxygen concentration inside the hood may reach 60%, depending on workload, and will then decrease for the duration of use. The oxygen flow is begun by semi-automatic activation.

Oxygen was selected as the breathable atmosphere because of weight and volume considerations. During respiration, oxygen is removed from the air and converted to carbon dioxide, which is then exhaled back into the air. If compressed air were used instead of oxygen, the air inside the hood would need to be constantly replenished to maintain the oxygen content at a life-supporting level. Because the VRU+ uses pure, aviator's grade oxygen, the exhaled air can be rebreathed once the carbon dioxide is removed. A typical industrial escape hood that relies on compressed air contains 350 L of air at 3,000-psi pressure. The VRU+ contains 18 L of oxygen at 3,000-psi pressure. The typical industrial escape hood weighs over 6 pounds. The VRU+ weighs just 1 1/2 pounds.

Carbon dioxide is a natural byproduct of respiration. Because the VRU+ is a closed circuit system, it is necessary to remove the carbon dioxide that builds up inside the hood. This is accomplished with a unique, patented passive scrubber. The carbon dioxide will be kept below 4% for the duration of use, but may reach a peak of 7% momentarily.

Duration of Use: All emergency rescue and escape situations are different, and it is not possible to provide an exact duration time for all situations. Also, the size of the VRU+ user will affect usable life, with heavier individuals consuming oxygen more rapidly. However, for an average male, the following typical escape situations are useful in predicting how long the VRU+ will last:

	Sitting, waiting to be rescued; Up to 60 minutes
	Waiting 17 minutes to be rescued, then rapid evacuation; Up to 21 minutes
	Moderate walking (3 mph); Up to 18 minutes
	Evacuation of a 110 Story Building; Up to 20 minutes
	Rapidly walking, on a flat, out of a building; Up to 8 minutes
	Rapidly walking up 15 flights of stairs; Up to 3 minutes

Packaging

The VRU+ is folded and sealed inside a multi-laminate pouch, which, in turn, can be packaged a variety of ways depending on your requirements including inside a fire resistant container. Containers are available with carabineers for carrying the VRU+ on web gear or belt. In addition, the VRU+ can be easily stored or mounted for industrial settings and can be donned in the near zero visibility atmosphere that may accompany a fire.
