you cannot have enough knowledge about this stuff LL
Should we sold safety? theorical question, but how closely relate to the subject first aid course
. some want to sold a course to make money, not for safety. some want more safety and suggest a course. The mentality of both are very different. One want to please a customer to untertain him for two days, the other will say the real thing: you can dye.
For a customer, it is fun to say in a meeting: you know I took a two days courses and we learn to do cardiac reanimation...so don't worry!!! But it is not fun to say: the guide pull me out of my stance and I felt three feet because I didn't belay my leader correctly. (I don't want to enter in a discussion if pulling litely someone of his stance or speaking to the guy his a good practice to remember safety, it worked with me long time ago).
In my opinion, first aid course most be a part of the beginer courses, a two hours or so, and it most be a follow up as the student graduate from one level to the other. The course most be realistic, like a simulation for beginer of a broken leg and the logistic to bring the climber to the car, with references on some good books and/or sugestion of courses for those who have too much work
to read about first aid.
Conclusion: climbing like a "pro", hard climb, take so much time that people skip other point of climbing. Cranking a 5.11 is more important than to avoid an accident and there will be always some guy to plug courses to make money instead of guy giving free time to save people (hope to be wrong, specially for the rescue team)
