I was playing devils advocate. Regardless of what subject matter is being delivered the person delivering the training has to be competent in the subject they are pitching, whether that be how to operate a fire extinguisher, or how to design and build a rocket engine. As I said before if not then what is the point of training if the instruction you are receiving is simply innacurate or wrong?
For example take your fella deputising for the main instructor. Im not saying he needs a degree in fire engineering, but you have to question, especially as this is a hopsital, what level of fire safety training is given, and, subsequently, what levels of competency is required of the trainer in order to give correct instruction. You then have to say is learning from the lead instructor parrot fashion adequate? It probably would be for basic stuff, but for more indepth subject matter it may not be.
