Welcome! I look forward to learning from you!
start with a complete search here. Many threads have discussed this in the past. Make sure to set the date range to all (it defaults to posts within the last week only and that is way too limited. There is a bunch of info here and you will only get the tip of the IceBerg if you limit your search to the last week.
Ideas That I remember from past discussions, some of which I use tho I'm not urban for either my job or home.
alternative transport - Bicycle is a good choice here get something for dual use - street bikes are too fragile and mountain bikes are not built for comfortable distance.
Building escape is more important that city escape.
Evacu-8 hood
Prybar
Zip-ties
Cordage -Everything from escape-rapelling through building stabilization to shelter tying has been considered and discussed. I carry enough for shelter construction but don't worry about building stabilization or escape rapelling since I work in single story and live in single story.
Work Gloves
Dust Mask
Goggles
Flashlights - Everything from flood-lights to keychain lights has been discussed. I have with me a 2XAA Maglite, an ASP saphire keychain light, a Photon II, and a Ray-o-Vac headlamp
Blades - multitool. I am a fan of the Leathereman Wave but this is a point of passionate debate on this forum and the two that seem to get the most press here are the SwissTool and the Wave. I also carry a camp-knife folder and some smaller Xacto type blades.
Water, Water, Water
Water purification means - filter, iodine or chlorine tablets, means to boil water Seem to be preferred in that order.
Water Carry options - Hydration bladder, Soda Bottles, Army canteen - Something. - Something to drink from - (small) and something to carry volumes with for sanitation etc. Something collapsible is best for the carry duty.
Power bars, granola bars, MRE, Mainstay Rations, Big jar of Goober - Some calorie dense food with a long shelf-life.
Copies of important documents like insurance, lisences, passports, birth-certificates, Credentials, wills, titles, etc
Copies of important documents like survival instructions, maps, phone-call lists, destinations, Meeting / messaging plans between you and spouse incase you are separated.
I have only scratched the surface of what is to be found in this archive. Please do a search of all posts with the keyword Urban and you will get more than you can read in an afternoon and all of it good!
Welcome and I am sure I will be learning from you soon!
