The article is meant to be an inspiration rather than a guide. Unfortunately it reads more as a list of must haves...

Anyway, the point is to look at your situation and evaluate your likely scenarios...then set up a few kits to assist. A desk kit with warm clothes and water, a car kit with battery cables, a body kit in case you need to evacuate your worksite....whatever fits your specific requirements.

One thing I always recommend to people is to start small....carry some money and your car and home keys at all times rather than leaving these items in a bag at work and wear some decent shoes that you can walk in. Adding a hat, gloves, radio, repair kit, FAK etc can come as you see fit or if you see fit.
