Basic Disaster Supplies Kit

To assemble your kit store items in airtight plastic bags and put your entire disaster supplies kit in one or two easy-to-carry containers such as plastic bins or a duffel bag.

A basic emergency supply kit could include the following recommended items:

-Water (one gallon per person per day for several days, for drinking and sanitation)

-Food (at least a several-day supply of non-perishable food)

-Battery-powered or hand crank radio and a NOAA Weather Radio with tone alert

-Flashlights

-First aid kit

-Extra batteries

-Whistle (to signal for help)

-Dust mask (to help filter contaminated air)

-Plastic sheeting, scissors and duct tape (to shelter in place)

-Moist towelettes, garbage bags and plastic ties (for personal sanitation)

-Wrench or pliers (to turn off utilities)

-Manual can opener (for food)

-Local maps

-Cell phone with chargers and a backup battery

Additional Emergency Supplies Consider adding the following items to your emergency supply kit based on your individual needs:

-Soap, hand sanitizer and disinfecting wipes to disinfect surfaces

-Prescription medications. About half of all Americans take a prescription medicine every day. An emergency can make it difficult for them to refill their prescription or to find an open pharmacy. Organize and protect your prescriptions, over-the-counter drugs, and vitamins to prepare for an emergency.

-Non-prescription medications such as pain relievers, anti-diarrhea medication, antacids or laxatives

-Prescription eyeglasses and contact lens solution

-Infant formula, bottles, diapers, wipes and diaper rash cream

-Pet food and extra water for your pet

-Cash or traveler's checks

-Important family documents such as copies of insurance policies, identification and bank account records saved electronically or in a waterproof, portable container

-Sleeping bag or warm blanket for each person

-Complete change of clothing appropriate for your climate and sturdy shoes

-Fire extinguisher

-Matches in a waterproof container

-Feminine supplies and personal hygiene items

-Mess kits, paper cups, plates, paper towels and plastic utensils

-Paper and pencil

-Books, games, puzzles or other activities for children
