I live very urban in the NY-NJ Metro Area. I have basically 3 different emergency kits.

One for my high rise apartment, assuming no electricity but availability of running water ( ususally not a problem since it’s a gravity system and gave us sufficient pressure to get water on the sseventh floor , with no pumps, even after Super Storm Sandy. If water is out for more than 3 days ,I need to relocate or get deliveries. I also need to refill my 8 , 5 gallon water cans. With some notice ,I can fill an oversized tub and get 40-50 gallons of water storage for cleaning and toilet flushing.

My second kits are in both my and my wife’s car. The goal is to be able to get in the car with 4 adults and no thought of needing to survive a calamity and if we get stuck in the car , we have enough food,water and equipment to survive for at least 72 hours. Not in great comfort , but we’ll make it in one piece, in any weather. Our cars , medium size SUVs with all wheel drive, We have a strap cutters in a visor pack, 4D cell, Maglites with drop-inLED bulbs, no leak batteries and window breaker end caps + xtra batteries, phone charging cables,each have a good tool kit ( SPAX tool, 21” Ti pry-bar, 24” bolt cutter, tow cable, reflective vest & triangles, chem lights and magnetic holders,jump cables, hack saw w. rod blades, emergency tire inflator sealant cans, and are also a camper.s loaded backpack, lifeboat rations, hard candies, and other survival items blankets, canned multi wick candles, small folding stove to hold the candles, , 10-12 25oz. water bottles, General Ecology hand pump water purifier, some cash, portable CB radios with battery packs, small inverters, etc..

My third kit is my EDC , city roaming kit, which underwent a complete redesign after 911. I wasn’t at the Towers, but I was close enough to watch the first tower fall, in vivid horrifying detail, with my unaided eyes.. So now if I’m in the City or nearin thereto ,I carry a small leather unisex leather backpack, ( coated in Snow-Seal ) about 8-9 liter capacity., 8-10 lb.s full, 2 Kyldex bag carry patches sewed to the bottom and waterproofed. Besides everyday meds (3x) , a waterproof pill bottle with Advil, ES Tylenol, caffeine pills, pseudoephedrine tabs , 8x 81mg. chewable children’s aspirin, Lomotil, generic Benadryl, a boo-boo kit ( which additionally includes splinter tweezers and dental repair/ cap glue kit), black tea bag( for oral bleeding or tea), 8-10 Wet Ones foil packets,, sewing kit, wax ear plugs, compressed towel disc, , flat plastic brush, hair gel in a waterproof pill box, disposable tooth brush waterproof pad ,space type pen, tissues, etc. a small plastic door wedge, I have an enhanced IFAK ( including Izzy type bandages , 2x TK-4 tourniquets, hemostatic gauze, nasal airway, chest seals , 8”x5” Combine Sterile Pad, 3” tight rolled vet wrap) and the knowledge to use it. XCaper Evac Mask and swim goggles, N-95 masks, nitrile gloves, extra liner socks, light Kevlar / leather gloves, sil-cloth poncho , yellow bandanna, Adventure Medical alumininzed blanket ( 2 person), e-light headlamp, + extra button batteries and 2AA flashlight with lithium batteries, Bic lighter and some hurricane matches + some tinder, small compass, extra eye-glasses, $500 in smallish bills, xtra credit card, photo of driver’s license , medical info, and a passport card, water purifier straw, water pur tabs ,and empty plastic liter water bags, fling plastic coffee filter holder and 4 paper filters ( small water bottle hung on plastic loop on outside of bag) , some M&Ms, hard candy and a 4 way sil-cock key. 10’ 2” flat rolled Gorilla Tape & 25’ 400’ test Kevlar cord. My IPhone has a Mophie battery case around it and survival apps. I also carry a LM Wave Tool, sometimes. I also maintain space for optional carry of an 8in Knipex wire cutter and an 12” Ti nail puller pry -bar. But that option is rarely utilized. There are many venues which will not allow even s small Swiss Army Knife. It’s a problem and requires some pre-planning. Basically airliner rules. This is in practice an E & E or Get Home bag, to get me out of a smoke filled subway tunnel , high-rise fire, patch-up me or mine, after a major trauma event , assist me in walking home and yet not look like I’m a traveling survivalist crazy when I walk into an nice restaurant or a Lincoln Center event.
