You have quite a problem here that an LED light and small knife will not help with.
I hope that you?re saying he needs a lot of prep
in addition to this rather than telling him not to bother having everyone on his staff carry (EDC) a small light, knife, whistle and fire starter. <img src="/images/graemlins/confused.gif" alt="" /> The value of a light and a whistle alone is pretty hard to argue after reading a few accounts by 9/11 survivors and survivors of earthquakes in urban areas. That's an excellent list of gear you made up... as long as it is accessible after a disaster. If not then the surviving individuals will be left with what they have with them.
