The communications equipment may include a multi-band receiver/scanner, a citizens band (CB) radio, portable "walkie-talkies" with rechargeable batteries, and a portable battery-powered television. The power supplies may include a diesel or gasoline generator with a one-month fuel supply, an auto battery and charger, extension cord, flashlights, rechargeable batteries (with recharger), an electric multi meter, and a test light. Defense items include a revolver, semi-automatic pistol, rifle, shotgun, ammunition, mace or pepper spray, and a large knife such as a KA-BAR or a bowie knife.
If the fire is around you and you can’t escape, you don’t have many options, says Shane Hobel of the Mountain Scout Survival School. If there’s a pool or a pond nearby, jump in and try to wait it out there. Otherwise, if you have time, dig a trench that’s two to three feet deep and long enough for you to lie in. Soak a blanket in water, wrap it around yourself, and lie down in the trench. It’s risky, but at least you’ll have a chance.
However, if some tales of survivalist stockpiling are to be believed, our nutty neighbors have enough of the social lubricant squirreled away to hold the most epic end-of-the-world-party of all time outside of Edgar Wright's social circle. It might not be practical, but who needs practical when you and everyone you know is doomed to die from radiation poisoning or cancer?
Don’t buy in bulk unless you plan to repackage your food into Mylar bags, vacuum-sealed bags, or canning jars. Once you open a large container of food—such as flour or coffee—the flavor and texture start to degrade. Storage containers provide an airtight seal that keeps rodents and pests out. Proper storage also keeps food nutritionally stable and extends the shelf life.
For global catastrophic risks the costs of food storage become impractical for most of the population  and for some such catastrophes conventional agriculture would not function due to the loss of a large fraction of sunlight (e.g. during nuclear winter or a supervolcano). In such situations, alternative food is necessary, which is converting natural gas and wood fiber to human edible food.
Hate to break it to you, but your dog probably has a better chance of making it through a total societal collapse than you do. A quick Internet search of "dog survives" lists everything from drowning to being shot, from bear attacks to war -- whereas the closest you've ever come to "surviving disaster" is getting your wisdom teeth pulled, and even then it was only with the help of a cadre of trained medical professionals and a carton of the strongest painkillers on Earth.
If you live in an area that experiences natural disasters that could result in an evacuation, it’s crucial to have a pre-packed bag with sufficient supplies for traveling. Convenient “grab ‘n’ go” survival kits have everything you need to stay safe, and well-fed while making your way to safety. Food, water purification tablets, personal blankets, and other necessities are provided in a duffle bag or backpack, so you don’t have to take the time to gather supplies before heading out. Typical kits contain enough food and water for 4 adults for 3 days.
As expeditions became more remote—through jungles, over mountains, and across ice—people required a survival kit small enough to carry on their bodies. That led to innovations in gear like the Swiss Army Knife, MREs, small but powerful flashlights, and other space-saving, multiple-use tools. Survivalists also borrowed useful everyday items like duct tape, can openers, and batteries for their missions.
However, a few unintentional similarities to the Quiverfull movement doesn't mean that preppers can't still care about safe sex. Hunting, canning, and digging your own latrines does nothing to make the threat of an STD less real. After all, gonorrhea and genital warts are going to be a whole lot harder to treat without reliable access to medical care. And there must be at least a few survivalists out there rational enough not to want to endure the horrors of premodern pregnancy and birth unless absolutely necessary.
Revealingly, however, many doomsday preppers’ fears are not based on speculative, sci-fi-style catastrophes but on disasters that have already happened. “Watch a documentary about Katrina. Look at something about Sandy, years afterwards. Look at Puerto Rico right now,” Scott Bounds, a member of N.Y.C. Preppers, says. “You have to realize that people are not going to come take care of you. You really have to be able to take care of yourself.”
Webb's includes an aspirin- and ibuprofen-filled pill bottle wrapped in duct tape and medical tape, a couple of gauze pads bound in a rubber band, and a standard gauze roll and a Kerlix gauze roll. It's enough gear to "stop a bleed and wrap it tight with the tape, or wrap a sprain and take the pain meds," he says. Webb packs it all in a Norelco shaver case.
Before fire season, move combustibles away from your house. Fences and dry vegetation give fires a place to grow, says Jonathan Cox at Cal Fire, California’s Department of Forestry and Fire Protection. Hosing down your house won’t help much, either, he says: “The way a lot of these homes burn is through something called ember cast, when embers from the fire fly over and drop little fires everywhere. With a huge ember cast, hosing down your house doesn’t do much.”
