Once again a point of discussion has been misinterpreted. Let's get back to the origin posting from Terry and then follow my reasoning.

It is conceivable for an oxygen cylinder attached to a stretcher to ignite combustible surrounding materials by one of the following methods:

1) The failing of an "O" ring allowing oxygen to come into contact with oil or grease. You can put all the quotes regarding measurement of how far it is recommended for oils and greases to be placed away from oxygen cylinders but in reality when these cylinders are attached to a stretcher it implies medical treatment is being performed. Fire fighters and victims are not always privvy to being that certain recommended distance from an oxygen cylinder. Nor can they always wash their hands beofre administering or receiving tratment, including their clothing. There are so many ponderables about this scenario including these, was the victim invloved in an autmobile accident, was the victim an automobile mechanic? Terry can perhaps shed light on this for us, in the meantime look outside the box!

2) Has the "O" ring been checked for integrity? What were the first materials ignited and have any statements from the medic or victim shed any light on the source of ignition?

3) My other point is, oxygen under pressure or not is a dangerous contributory factor in the source of ignition and fire spread, hence my reference to John Lentini's photograph.

3) Where was the stretcher? I think I am right in saying not too many stretchers are fixed objects,so how can one regulate the positioning of a stretcher so it is kept, according to code, 20 feet from an oil or grease material. Then let us provide a five feet high and 1/2 hour fire resistance barrier around the stretcher, oh dear me. What are you thinking?
