Hey everybody, its raining! You know what that means… somewhere there are a bunch of very jubilant UCSC students.
I guess it also means your power might go out (due to the wind advisory currently in affect for our county). So, here is our most popular blog post, ever… What to do when your power goes out. Read it quick.
If your power goes out, here are some steps you can take to keep your family safe.
- Use a flashlight for emergency lighting. Never use candles.
- Turn off electrical equipment you were using when the power went out.
- Avoid opening the refrigerator and freezer to keep your food as fresh as possible.
- Do not run a generator in an enclosed or partially enclosed space, such as your home, garage, basement, or crawlspace. Never burn charcoal for heating or cooking indoors. Never use your gas range, oven, or dryer as a source of heat.
- If you use a generator, connect the equipment you want to power directly to the outlets on the generator. Do not connect a generator to a home’s electrical system.
- Use a portable radio for updated news and weather forecasts.
- Leave one light on so you know when the power returns.
Everyone can prepare ahead of time for disasters like a power outage by taking the following actions:
- Build a disaster supplies kit. Your kit should include at least a three-day supply of non-perishable food items and water (one gallon per person per day), a flashlight, a battery-powered or crank radio, as well as batteries, can opener and special items such as medications, diapers, and infant formula.
- Have a communication plan ready. If you have a telephone that requires electricity to work (such as a cordless phone or answering machine), plan for alternate communication, including having a cellular telephone, radio, or pager.
- Keep your car fuel tank at least half full because gas stations rely on electricity to power their pumps.
- Be sure to keep a key to your house with you, in case the garage door does not open. If you have an electric garage door opener, find out where the manual release lever is located and learn how to operate it.
- Follow energy conservation measures to keep the use of electricity as low as possible.
How to keep food safe during a power outage
Sudden power outages can be frustrating and troublesome, especially when they are prolonged. Perishable foods should not be held above 40 degrees for more than 2 hours. If a power outage is 2 hours or less, you need not be concerned, but how do you save your food when the refrigerator is out for longer times? Being prepared can help. By planning ahead, you can save your perishables.
What do I need?
- One or more coolers. Inexpensive styrofoam coolers can do an excellent job as well.
- Shelf-stable foods, such as canned goods and powdered or boxed milk. These can be eaten cold or heated on the grill.
- A digital quick-response thermometer. A digital thermometer should be a necessity in your kitchen anyway. With these thermometers you can quickly check the internal temperatures of food for doneness and safety.
What to do…
- Do not open the refrigerator or freezer. Tell your little ones not to open the door. An unopened refrigerator will keep foods cold enough for a couple of hours at least. A freezer that is half full will hold for up to 24 hours and a full freezer for 48 hours.
- If it looks like the power outage will be for more than 2-4 hours, pack refrigerated milk, dairy products, meats, fish, poultry, eggs, gravy, stuffing and left-overs into your cooler surrounded by ice.
- If it looks like the power outage will be prolonged, prepare a cooler with ice for your freezer items.See “Power is Out” download guidelines (PDF file)
Q’s and A’s
What should be discarded after a power outage? As soon as the power returns, check temperatures. If the food in the freezer has ice crystals and is not above 40 degrees you can refreeze. Perishable foods in the refrigerator should not be above 40 degrees F. for more than two hours. Use this chart to see what has to be discarded and what can be kept.
What if I go to bed and the power is still not on? Before you go to bed, pack your perishables into your coolers if you haven’t already done so and put in as much ice as you can. Also, when you go to bed, leave a bedroom light switched on. When the power goes back on, it will wake you, so you can check the condition of your foods in the freezer.
What if the power goes out while I’m at work or out of the house and it has been more than a few hours before I get home? Try to determine how long the power has been out. Check the internal temperature of the food in your refrigerator with your quick-response thermometer. A liquid such as milk or juice is easy to check. Spot check other items like steaks or left-overs also. If the internal temperature is above 40 degrees, it is best to throw it out.
What if the power goes out and comes back on while I am out? If your freezer is fairly full and you know it was not longer than 24 hours, the food should be OK. There will be loss of quality with refreezing, but the food will be safe. If the refrigerator was out for more than 2-4 hours, you are best to discard the perishables.
