OXYGEN CLEAN & OXYGEN COMPATIBLE
On the Baby Booster WARNING page, it states that great care must be taken to ensure that all equipment is oxygen clean and that oxygen compatible parts and lubricants should be used. While it is important that we start out with everything oxygen clean, it is very important that all gas blenders understand that oxygen clean is a point in time!!
An item can be oxygen clean for a brief period but once put into service it should always be considered to be contaminated to some degree.
As stated on the Baby Booster warning page, we need oxygen, fuel and a source of ignition for an oxygen fire or explosion to occur. Oxygen is obviously present and when dealing with high pressure gases, almost everything can be considered fuel. Even stainless hose fittings will burn in high pressure oxygen. That leaves the source of ignition. The most common sources of ignition in a gas booster are particle impingement and heat generated by compression. Particle impingement can be avoided in two ways. First, by attempting to keep particles out of the system. While this is an obvious solution, for all practical purposes it is impossible. The system will be contaminated. The second solution and this also relates to compression heating, is to ensure that any particles in the system are not accelerated to the degree that they can cause ignition.
This is where the rule of opening the tank valves slowly comes in. Open the tank valves slowly, allowing the pressure to equalize across the booster when the supply pressure is higher than the fill pressure before starting the booster, and then open the drive gas valve slowly. Do not try to use the gauge as an indication of how slowly the pressure in the system is increasing. Most gauges have built in “snubbers” to prevent damage and will show a slow pressure increase even when the valves are opened quickly.
The most likely points of ignition when using a booster are the supply and fill whips attached to the booster. Opening either of the tank valves too quickly can easily generate enough heat to cause ignition. If the fill whips have quick connect fittings or other restrictions the risk of ignition is increased.
If you boost oxygen you will eventually have an oxygen fire. The risk can never be reduced to zero.

WARNING
Only those individuals, who are professionally certified as gas blenders and understand the increased risks of working with high-pressure gases such as air, oxygen, and helium, should operate this booster.
When boosting oxygen, great care must be taken to ensure that all cylinders, lines, whips, and any other equipment are oxygen clean and the proper lubricants compatible for oxygen are used.
It is imperative that when handling oxygen great care is taken to open all valves extremely slowly. Remember, the needle on your gauge moves at a preset rate. You cannot judge the speed of the gas flow by watching this needle.
Remember for an oxygen fire to occur, three sides of the fire triangle must be in place. First, you must have oxygen. Second, there needs to be fuel present. The fuel is generally oil or another contaminant located within the cylinder or poorly maintained filling system. Third, you need heat in the form of a spark to complete the source of ignition. When opening a valve too quickly, the force of the flow can cause the heat source.
OPEN ALL VALVES SLOWLY!!!!!!!!!!!!!!
THE OWNERS MANUAL SHOULD BE READ IN FULL PRIOR TO OPERATING THE BABY BOOSTER!!
