hey...
just some basic thoughts:
just store what you eat and drink. and then rotate it aus you use it. first in goes first out.
just enlarge your normal pantry step by step
get stuff that is ready to eat, that you like and that stores well. canned stews, canned saucages, canned fish, canned nuts (salted peanuts), peanut butter etc.
get some dried dried fruit and berries. candy bars, granola bars etc.
stuff that you could eat for a few weeks without much preparation needed.
this saves you time in shopping. just by some more of the items, you would normally buy and eat.
storing water: if it s tight and out of sunlight, storebought bottled water will last for decaeds probably. if you fill your own, there are agents that hinder growth of bacteria. there s a well known brand here for that: micropur (i think by katadyn). it has silver ions something. it just preserves clean water, it does not kill germs if they re still presence. but in that case you still have steripen
cleaning jugs: i ve read about people using pool shock chlorine to desinfect water. so it should be safe for cleaning jugs and the rinsing. but read
online about it, you ll find infos wether it s safe. i would go for saturated salt solution, or vinegar or high proof alcohol. should be safe enough.
what about heat?
it would
be nice to have some electric
energy stored. a car battery (not store in your living space) with a charger. hook a 12v USB plug for the car-cigarette-lighter jack to that and some simple
led 12V household
lights.
and have a plan to get out and or people to trust for help.
you could search for videos of
jack spirko on youtube. i think they are called "modern survivalism" or " 6 planks of modern survivalism" or something. they re very basic and with good common stuff.
but ... i think that at the moment you re a big step better prepared than most folks are....
