Earthquake Safety Tips

Earthquake Readiness 

In preparation for a potential earth quake, we should all be prepared with emergency supplies at home, including a three- to five-day supply of drinking water for every member of the household.  Remember that in case of an earthquake, you may lose power and water service for up to a few days.

  • Store tap water—at least one gallon per person (don't forget pets) per day—in clean, plastic, airtight containers in a dark, cool place. 
  • Store enough to last at least three to five days.
  • Label each container with a date and replace the water every six months.   
  • If you need to use the water, add 16 drops of bleach to each gallon to ensure disinfection. (Use pure household bleach only—not products with scents or other additives.)  Mix and allow to stand for 30 minutes before use.  If a camp stove is available, you can also disinfect the water by bringing to a rolling boil for 5 to 10 minutes.  
  • If you run out of stored drinking water, strain and treat water from your water heater.  To strain, pour it through a clean cloth or layers of paper towels. Treat with household bleach, as directed above. Other sources of water inside the home are ice cubes, and the reservoir tank of your toilet (not the bowl). 
  •  If your water supply is not sufficient for hand washing, use antiseptic hand gel or wipes.
