I thank Deputy Healy-Rae for that. I am quite sure that the ambulance service will determine the real cause of this, whether it was somebody inadvertently not tightening nuts properly or an incorrect configuration. In any event, it is lucky that the driver took appropriate action and was in charge of his vehicle, that another ambulance arrived within five minutes and that the patient was brought safely to UCHG with no change or lack of attention to the patient in question.
