It's obvious you guys have given this subject a lot of thought. I'm glad I asked the question here and I appreciate the responses. I've learned a lot and am much better informed thanks to your input.
It seems I need to prepare at least two and perhaps three different layers of equipment/supplies. 1) Those I carry on my person. 2) What I might keep in a bag near me. and 3) stuff I keep in my vehicle.
look at it this way:
WHERE do you work? how many floors up? how many exits? is your vehicle accessible? how much water is on each floor? how many EXITS? how many people do you work with? how many of them are prepared? how many miles between your work and home? how many ROADS between you and home?
electrical hazards? creeks (flooding???) , obstacles between you and home? disaster plan at work?
etc
