Interesting topic! Looks like you have a lot of coverage and I see some items, as others have said, that may be overkill. But it all depends on where you are located in an emergency I guess. I gave everyone’s replies a read or two and I thought about the whole subject a bit and concluded that there can be many scenarios and many tools that may be nice to have along. However, I see some issues. For instance, if your kit is too big and you can't carry it constantly, you may not have it when you need it. Say you work on the 50th floor of a high-rise and leave your kit in your office when called to the 20th floor for a meeting and there is a fire or other emergency, you will not likely be going back up 30 floors to get your gear.
With that sort of thought in mind, let me tell you what I carry and perhaps why.
I carry a cell phone, car keys a SAK Rambler knife and a PhotonII mini-light on my person at most all times. Just basics. In a small waist pack I carry a Doug Ritter PSK, an Infinity Tasklight, a very small AM-FM radio with earbud, a SOG Paratool, a small roll of toilet paper, a TMRU shelter and a list of emergency phone numbers. I also keep 2 bottles of water handy. The reason I don't carry more is that I don't see a situation everyday when I would need more than that. There are first aid kits located in all 8 buildings at our campus, there is a fire department a few minutes away, police also. If I worked and traveled elsewhere, my carry items will be based on the perceived needs of that journey. I travel a heavily traveled freeway to get home and have broken down after getting off a rather remote exit, at 115 degrees outside, I wanted water and a cell phone! Not much else would have helped, except a new car, I got that later!!
Friday there was a heavy, fast moving storm that interrupted my trip home, along with an accident on the freeway, blocking movement. I got off on a side road, which was overly saturated with both water and traffic, so I decided to pull over to a restaurant and have dinner while water drained off and traffic thinned out. I used the cell phone to call the family to tell them where I was and why. It had not rained at home and never did.
I do not mean to be critical of your kit, I just think everyone needs to evaluate their potential emergencies and plan accordingly. Why carry band aids? Yeah they are small and light, but can you live without them? Yes! I guess after a few combat tours in the army I learned to use what I have and get by with it. Sure it would have been nice to have some items once in a while, but then they were not available to me at the time. And looking back, I am glad I didn't have to lug them around all over!
When I go to the wilderness or through the wilderness, I have a lot more with me and can deal with most circumstances that may arise on that journey. I guess just plan for what is likely, potential and probable. In general, don't plan for a hurricane in Kansas. Cheers!
