Looks like a good kit to me.

You might consider a CPR barrier (Laerdahl) in the event a co-worker vapor locks and you end up doing CPR (unless you're trained to do compression-only CPR, and that's fine).

I like a trusty crow-bar in my office kit: getting out of my office door is task #1, and in the last EQ a number of office doors jammed from the shaking. You can leave that at work if you don't want to truck it all the way home with you.

Money in addition to the roll of quarters. Maybe enough to get a room at a nearby hotel/motel. If you don't have a secure place to keep this in your workplace, then keep it in your car or try to keep enough cash on your person.
