A year on from posting this comment and knowing more now than I did then, I think no use of any lights, red, orange, green or blue should be used by CFR's. I have met CFR's that are a disgrace and simply can’t be trusted to use a tea light let alone a blue light. The problem is that, unfortunately, the very nature of this voluntary work attracts the Walter Mitty's and it’s impossible to detect these sad characters until its too late. The training, certainly for the trust I am a CFR for, is not adequate and I am becoming increasingly cynical about the way CFR's are regarded by the management of the trust. Don't get me wrong, there are a great deal of CFR's out there who do it for all the right reasons and are a credit to their communities and Ambulance Trusts but, as is often the case, the minority spoil it for the majority. Of course this line of work is to serious to have such people out in the field without adequate training and suitability assessments. CRB checks are not enough in my view. The whole national CFR model needs to be revisited and a strict code of conduct needs to be adhered to which includes regular top up training and reassessment. Only such action will give the CFR principle any kind of credibility. In fact I feel so strongly about this that I intend to write to the governing body responsible for this.
