This step makes sense. Random first aid person carrying an injector without proper knowlege on how to use one seems a bit... short-sighted. Sure, those 6-year-olds know how to use them because they've been trained on how to use them. So have their caregivers. Usually this is because they might need to use one on themselves, a sibling, or a parent - who has a known condition. The random person that doesn't come in contact with such a relative or housemate, however, might not even properly recognise the reaction. Even when they do, they still need the training on how to use the pen so they know how to respond. The prudent thing to do in these cases is to give a first aid and CPR course to those that wish to have one.
