International guidelines for safety in adventure travel are tougher to find than you'd think, so here:
Firstly, one has to accept that the term 'adventure' itself implies that there are inherent risks involved in the sport. Still, there are many who get injured or even die from mundane activities like crossing the road than from participating in adventure sports. Why is that? The way I see it is that most adventure travel companies today are aware of the risks involved and they train their staff accordingly. They are always prepared with back-up safety plans in case of any untoward incidents.
