Ok let's finish.

Cooking odors, cooking Will produce odors, fuel, food seasoning,etc. Store foods with minimal spices. If surrounded by starving people a can of chili con Carne could be a death warrant. If you get my drift?

Firefighting, just acquire at least 2 large multipurpose (ABC) chemical fire extinguishers.

Exercise, you need to maintain muscle tone. Put a pull-up bar in a door frame, large elastic bands. If in budget q stationary bicycle powered generator, to allow exercise and battery charging.

Sanity, You have family so mentality at least you have company otherwise, have lots of reading material. For the family board games, a deck of cards. Just remember noise discipline while playing.

Last and most important. Noise and Light Discipline, if you make noise or have any source of light undesirables will notice you. Lit up apartments will be deemed worth robbing. I suggest NO light except as absolutely nessesary. If you are to have a light source you MUST be prepared to black out ALL windows in your apartment. Sadly this counters your ventilation for heating and cooking. Any vent holes must be covered for night if a light is used.

Iron, I don't know your entire situation I know mine is tight. But if you can get out now. See if friends or family out of city can take you in if need be. Don't showup empty handed and they should be glad to see you on their doorstep.

Also ramen noodles will let you starve with a full stomach they have no nutritious value to speak of.
