How To Be Ready When the Electricity Goes Out

Electricity is a crucial part of modern 21st century life. Reliable access to electricity allows us power our computers and phones, keep our food cold, stay comfortable when the weather is nasty outside, and more. However, our power grid is vulnerable to interruptions due to man-made factors like a spike in demand on a hot summer day, terrorist attacks, or human error as well as a natural disaster like a blizzard, tornado, or a hurricane.

You need to be prepared for a power outage because it can turn a modern neighborhood from a family-friendly place to a third world country where people are willing to take desperate measures. Because outages are so unpredictable, you need to know how to cope with them and how to prepare in advance, as we've detailed in the guide below.

Water SafetyPower Outage

Power outages may disrupt the municipal water supply provider's ability to keep water purified. Prepare for this possibility by storing one gallon of water per person per day in reserve, and increase that amount to one and a half gallons during the summer. Spare water can also be kept in the freezer and refrigerator's freezer section to help keep the space packed. It is also possible to boil water in a pot over a fire for 60 seconds for use during a prolonged blackout. Boiling is the only effective way to kill microbes lurking in the water.


In the event of a power outage, a spare cooler with a supply of ice will keep perishable foods like meat and dairy products below 40 degrees Fahrenheit for longer. Above this temperture harmful microbes rapidly spoil the food. To know for sure the temperature of the food, a digital thermometer should be kept with the food. Freezers, if they are full, will preserve frozen food for up to two days. One way to keep them full is to use ice packs, or stored ice. Opening the freezer door reduces the amount of time that it keeps food frozen, especially when it is opened during the hottest part of the day. Food that can't be kept below 40 degrees should be cooked via outside barbecue and eaten, if possible, before it warms up. If this isn't possible then it will be necessary to discard the food.

LightingEmergency Lighting

Power outages are often called blackouts because lights out are the most apparent consequence of losing electricty. Traditionally people have dealt with the darkness by using flashlights and candles. The Red Cross, however, recommends against using candles during blackouts because they start so many fires during power outages. Darkness is not life threatening, but a house fire is. If candles must be used, be sure they are kept away from flammable objects, are placed in a stable holder, and are never left burning unattended. The best lighting solution is an LED headlamp. They have bright lights, consume little power for long battery life and allow hands-free operation. An additional option are nightlights that double as emergency lights. The battery charges while plugged in to the electrical outlet and provides emergency light when the power goes out.

Staying Connected

Electrical service disruptions can have an adverse effect on communications. The FCC mandates that cell phone towers must have four hours of battery backup power, which won't last through a prolonged outage. Internet phones, or Voice-Over-IP services, are also unlikely to continue functioning. Traditional land line service will continue to work, although cordless phones will stop working unless they have a battery backup. For the sake of preparedness, it is necessary to keep land line phone service even if this amounts to an added expense.

Carbon Monoxide PoisoningEmergency Generator

Carbon monoxide is a colorless, odorless gas that can accumulate while burning wood or charcoal or running a generator. In areas with poor ventilation carbon monoxide can displace oxygen and present a lethal hazard for residents. It is unsafe to burn wood anywhere except in a fireplace, or to use a barbecue inside of a house or any other enclosed structure. Using a generator in any enclosed space, including an attached garage, is also unsafe because it leads to potentially deadly carbon monoxide buildup in the home.

Power Failures in Summer

Service disruptions in the summer can come as a result of tornadoes, hurricanes and thunderstorms, as well as an increased demand for energy due to the widespread use of air conditioners. Blackouts during this time of year are dangerous because they cut off access to air conditioning and can result in heat strokes and other heat-related health problems. To prevent these issues from occurring it will be necessary to open windows if there is a breeze outside, and to drink at least a gallon of water or non-alcoholic beverages per day per person, or more if the temperature is very hot. In addition, people should stay in the shade when possible, open windows when there is a breeze, and wear clothes with light colors because light colors help clothes to reflect light and stay cooler. Cool showers and baths also help a person keep cool, and work should be done during the cooler times of the day when possible. It will be necessary to look out for signs of heat-related illness in oneself as well as others. These signs include the onset of nausea, weakness, dizziness, confusion, or hot and dry skin. Those suffering from these symptoms must receive immediate medical attention.

Power Failures in Winter

During the winter, accumulations of snow can collapse power lines and power poles, as can ice storms and blizzards. Homes with fireplaces, pellet stoves and gas furnaces without electric ignitions will be able to stay warm as long as its residents stock up on the proper fuel in advance. Houses without these types of heating systems will rapidly become unsafe for habitation during a prolonged period of electrical service disruption. The primary threat that people face during power outages in the winter is hypothermia, or excessively low body temperatures caused by cold or freezing external temperatures. To avert this potential health hazard it will be necessary to wear thick clothing that insulates heat. In addition, covering beds with extra blankets will hold in heat while a person sleeps. It may also be necessary for people to share body heat to stay warm longer. Symptoms of hypothermia include numbness in the feet or hands, stumbling, excessive shivering, slowed heart rate, or the onset of lethargy, confusion or delirium.
