The last time we had a power outage I learned a few things....
1. Lights-While I had plenty of bright flashlights, they tend to blind you for short range work and you don't really need them for walking around in the house. What you need is some low level ambient lighting. Eyes get used to low light levels and I am not sure you want to light up your house when everything else in the neighborhood is dark. Candles/oil lamps work but give off too much heat in the summer. Gas lanterns work as well but are better for large areas and give off a lot of heat.
I used chemlights/snap lights for awhile. They give off enough ambient light to walk around the house, use the bathroom etc. They are also good for marking stairways or other things. I also found that a LED headlamp, or one of those little LED lights that hook onto the bill of a baseball cap were real handy for shutting electrical circuit boxes down, starting generators etc. One thing that was handy was a small LED lantern. I had one and it gave off more ambient light than the chem lights but not so much to light the whole place up. After our outage I bought 4 more.
2. Generator-So I drag my gen-set out of shed. It is dark and raining like hell. It has been awhile since I used it and can't remember the exact start up procedure. It is dark and I can't find the on switch. I can tell which way the gas valve is supposed to turn on, and the choke is supposed to be set on half first. I can't read the teenie tiny direction label without my reading glasses and then they get wet and still can't read. The frickin' tactical flashlight I have is so bright it reflects off the shiny label and I still can't read it.
So, the next weekend, I go out with my white paint pen and write in big letters the procedures 1-4. I label the switch, the choke and gas valve in large numbers that correspond to the directions. I also indicate in large arrows and letters, which way is on and which way is off on everything. To test it I send my wife out to the patio and tell her to read the directions and start the generator. 1. Fill with gas: Wife- "do I have to fill it with gas?" Me-"read the directions". Wife "where's the gas?" Me-"in the red gas can next to the generator, geez, nevermind". Don't assume other people know what you are thinking or talking about.
3. Alternative power- One thing that came in handy was one of those portable jump start battery pack things. The one I had has a jump starter cables, air compressor, LED light, inverter and a couple 12V plugs in it. We used the LED lights, plugged the portable radio into it and a small 12V fan for about 7 hours. Not as good as a generator but can get you through until you get your gen-set up and running.
4. Emergency Cupboard- Ok, I have BOBs, & GHBs. I have FAKS. I have shelves in the basement stocked with stuff. I have a closet in the basement full a gear and safes full of guns. I have battery recharging stations. What I didn't have was one place on the main floor of my house that I could just walk over to, open up and pull out flashlights, headlamps, LED lanterns, candles, matches, chemlights, batteries, radios, extension cord, shed keys etc. When the power went out I had my flashlight close by but I had to go around and grab the rest of the stuff from various places. Set up a cupboard in the main part of your house as a one stop place you can go to get through the first 20 minutes to an hour. It will save you time and frustration. The reason I suggest a cupboard is because bags, cases, boxes, ammo cans and such get moved around and may get misplaced.
