Since publishing my post that included advice for avoiding bear attack in the wilderness, I have had a few questions from people about how to defend against an attacking bear, and in particular, about the role of "bear spray."
Pepper spray marketed to repel bears definitely has a role, but should not be completely relied upon to deter an aggressive or charging bear. So avoidance of up-close bear encounters is the most important safety issue, and should never be forgotten.
If you are going to carry bear spray, here is some important information assembled from the writings and lectures of experts (including Steve French, M.D., Luanne Freer, M.D., Timothy Floyd, M.D., and Stephen Herrero). I also gleaned excellent information from the UDAP Industries site:
