I was under the impression that as long as an AED and O2 (as a minimum) were on scene, the ORCON clock could be stopped (that is to say if for instance I as an SJA member were to happen across an incident on my way to/from a duty, and had these available, the ORCON time from my call would be 0 minutes). Surely this works the other way too - if you have no O2 masks, you can't give O2, and therefore the great god ORCON will not be pleased! Obviously not, however
