Frequently Asked Questions

Quick answers to the most common questions we get about emergency preparedness.

Food & Water Storage

How much water should I store per person?

The standard recommendation is 1 gallon (3.8 liters) per person per day — half for drinking, half for hygiene. For a 2-week supply for one person, that's 14 gallons. Start with 3 days (3 gallons per person) and build up.

What's the best emergency food to buy?

For shelf life and ease, freeze-dried meals (Mountain House, Augason Farms) last 25–30 years. For cost efficiency, canned goods and dry staples (rice, beans, oats) work well with rotation. See our best emergency food supply guide for detailed comparisons.

How long does bottled water last?

Commercially bottled water is typically good for 2 years from the bottling date when stored properly (cool, dark place). After that, it's still safe to drink but may taste flat. Rotate your supply yearly.

Can I drink tap water after boiling?

Yes. Boiling water for 1 minute (3 minutes above 6,500 feet) kills bacteria, viruses, and parasites. For chemical contaminants, you'll need a filter or distillation.

How much food should I store for one person for 3 months?

Aim for roughly 90,000–120,000 calories per person depending on activity level. That's about 60–80 lbs of dry goods (rice, beans, pasta) plus freeze-dried meals, canned proteins, cooking oil, and comfort foods. Use our food calculator for a precise estimate.

Bug-Out Bags & Emergency Kits

What should be in a basic 72-hour kit?

At minimum: water (3L), food (no-cook, 3-day supply), flashlight, first aid kit, multi-tool, whistle, dust mask, local maps, emergency blanket, phone charger/cable, and prescription medications. See our complete 72-hour kit guide.

Do I really need a bug-out bag?

If you live in an area prone to wildfires, floods, or hurricanes — yes. If you live in a low-risk urban area, a go-bag for extended power outages is more practical than a wilderness survival bag. Assess your actual risks first.

What's the best multi-tool for emergencies?

Leatherman and Victorinox are the most reliable brands. For emergency use specifically, we recommend the Leatherman Wave+ or Signal — both have pliers, knife, saw, and bit driver in one tool.

Preparedness Basics

I'm on a budget — where do I start?

Start with the basics: store extra water, buy a good flashlight and first aid kit, have a 3-day supply of non-perishable food. That's under $100. Build from there. See our budget preparedness guide.

Do I need a generator?

Not everyone does. If you have medical devices, a deep freezer, or work from home, a solar generator might be worth it. For most people, a power bank for phones and a camp stove for cooking covers the real needs for a 3–5 day outage.

What about first aid training?

We strongly recommend taking a Red Cross First Aid/CPR course before buying any first aid supplies. The best kit is useless if you don't know how to use it. Check Red Cross courses in your area.

How do I prepare if I live in an apartment?

Space is the main constraint. Focus on compact water storage, stackable food containers, and a go-bag approach rather than bulk storage. See our apartment preparedness guide for strategies that work in small spaces.
