Experts recommend that each person (and pet) has supplies for at least three days, including bottled water (two quarts per person, per day), nonperishable food, and a first-aid kit that includes prescription items as well as aspirin and antacids. Make sure you have tools such as a can opener, utility knife, wrench (for turning power valves), whistle, battery-powered radio, several flashlights, and batteries. Each person will need blankets, clothing, rain gear, and heavy-soled shoes or boots. Lastly, stash away some cash and a copy of credit cards, passports, social security cards, phone numbers, and insurance information. Once a year, check your supplies and determine if family needs have changed.
