Be prepared — what you do immediately after an earthquake may prevent injuries and significant financial loss.

Preparing for an earthquake takes two forms: physical preparation (equipment and supplies) and mental preparation (knowing what to do).

EQE International believe that the average California home, with a few simple additions, has the supplies and food on hand to last up to 72 hours. State and local officials advise residents that outside help after a large, damaging earthquake may take up to 72 hours. Based on our experience, if you live in an urban area, you should expect help within 24 hours after an earthquake. However, immediately following an earthquake, help from local fire and police departments will not be available. Be prepared to administer first aid or put out a small fire. Listed below are a few suggestions and hints on how to best utilize the resources at hand.

• Water. The water heater (30 to 40 gallons) for a family of four should contain enough water to last four days. The toilet tank can provide up to 7 gallons of water. Ice cubes in the freezer and liquid from canned food can be used. We recommend keeping purification tablets on hand rather than trying to store extra water.

• Food. Most houses have ample food on hand to last several days. Use food in your refrigerator and freezer first. If there is no power, frozen food will keep three days in an unopened freezer.

• First Aid. Most homes have the items necessary to handle routine accidents. A first-aid kit and a book on first aid should be kept in a central location. We recommend taking a first-aid and CPR course from the Red Cross.

• Fire Extinguishers. Have one or more fire extinguishers. Learn how to use them! Have your fire extinguisher serviced annually to be sure that it is working properly.
