- For the Freezer section: A freezer that is half full will hold food safely for up to 24 hours. A full freezer will hold food safely for 48 hours. Do not open the freezer door if you can avoid it.
- For the Refrigerated section: Pack milk, other dairy products, meat, fish, eggs, gravy, and spoilable leftovers into a cooler surrounded by ice.

When power goes out, water purification systems may not be functioning fully. Boiling water, when practical, is the preferred way to kill harmful bacteria and parasites. Bringing water to a rolling boil for one minute will kill most organisms. If you don't have clean, safe, bottled water and if boiling is not possible, you often can make water safer to drink by using a disinfectant, such as unscented household chlorine bleach, iodine, or chlorine dioxide tablets. These can kill most harmful organisms, such as viruses and bacteria. However, only chlorine dioxide tablets are effective in controlling more resistant organisms, such as the parasite Cryptosporidium.
To disinfect water, filter it through a clean cloth, paper towel, or coffee filter or allow it to settle. Draw off the clear water. When using household chlorine bleach, add 1/8 teaspoon (or eight drops; about 0.625 milliliters) of unscented liquid household chlorine (5-6%) bleach for each gallon of clear water (or two drops of bleach for each liter or each quart of clear water). Add 1/4 teaspoon (or 16 drops; about 1.50 milliliters) of bleach for each gallon of cloudy water (or 4 drops of bleach for each liter or each quart of cloudy water). Stir the mixture well. Let it stand for 30 minutes or longer before you use it. Store the disinfected water in clean, disinfected containers with tight covers.
Be aware of yours and others' risk for heat stroke, heat exhaustion, heat cramps and fainting. To avoid heat stress, you should drink a glass of fluid every 15 to 20 minutes and at least one gallon each day. Avoid alcohol and caffeine. They both dehydrate the body. Wear light-colored, loose-fitting clothing. Take frequent cool showers or baths.
Power Line Hazards and Cars
If a power line falls on a car, you should stay inside the vehicle. Warn people not to touch the car or the line. The only circumstance in which you should consider leaving a car that is in contact with a downed power line is if the vehicle catches on fire. Open the door. Do not step out of the car. You may receive a shock. Instead, jump free of the car so that your body clears the vehicle before touching the ground. Once you clear the car, shuffle at least 50 feet away, with both feet on the ground.
Do not try to help someone else from the car while you are standing on the ground.
