These are my instructions for me and my family with a eye toward if I was a newbie.
My instructions for me:
1) Don't panic.
2) Don't max out the credit card. If tempted to do so refer to #1.
3) Know what I already have in stock, how much and if it's in date.
4) Have a budget and stay within it. See #1 & 2.
5) Make a list and assign priorities to each item. Be flexible depending on priority and what's available.
Food: I looking for shelf safe convenience foods that my family will eat.
canned soups, canned meats, canned veggies, Stove Top Stuffing, tasty pasta and rice sides, canned fruit. I pick a four or five meals my family will eat and find shelf safe components. Then I buy all the components for a meal or two and build on that each shopping trip. Remember snacks and deserts: popcorn, Jello pudding, muffin mixes, trail mix, candies, box desserts like brownies, cakes and cookies.
OTC medication. Check with my healthcare professional for guidance. Want to be prepared for most common emergencies we've run into or might that OTC meds can mitigate.
Emergency equipment: This is for my family. YMMV.
Medical: BP cuff, Stethoscope, thermometer, Fingertip Pulse Oximeter (batteries?), general first aid etc. Make sure scripts are filled. Preventive maintenance: Annual medical checkup, dental checkup and cleaning, eye exam.
Fire: extinguisher*, welding blanket, smoke detector test(new batteries)
Other: Propane stove for cooking if power outages or brownouts occur. Flash lights, lantreens (wicks, fuel, extra chimneys - they break). 72 hour Go Bag and Go Totes. The difference is go bag is on foot or emergency bug out. Go Totes are for a vehicle bug out or bug in to make life more comfortable than just a Go bag.
*Fire extinguisher: Different types of extinguishers, extinguish different types of fires more effectively than others. The right tool for the right job sort of thing.
Car: Annual Inspection with eye toward current and potential problems.
House: Annual Inspection of all major systems with eye toward current and potential problems. A walk around inspection of the home checking for termite tubes and cracks on the foundation, leaks in the roof, missing or damaged shingles, leaking pipes etc. Basically what a home inspector would look for, for a potential buyer.
Make sure periodic maintenance is up to date:
Septic tank pumped out every other year.
Fireplace chimney cleaned and inspected (every year).
Furnace inspection (DH's call on that)
Top off home heating and cooking fuel tanks. We usually do this in summer when prices are cheaper.
New Batteries in fire alarms (twice a year - when clocks are turned back or forward works for us).
A lock down can be an inconvenience or emergency depending upon preparation and mind set. While a big emergency is happening little ones can also happen. Preventive maintenance and the right tools, supplies and know how may be able to prevent or mitigate them.
