Even if you don’t usually get extreme snow storms, it’s important to be prepared for one. The moment you find out a heavy and dangerous blizzard is headed your way, make the necessary preparations to protect yourself and your family. Along with these winter safety tips be sure to place the number of our local Mount Prospect roof repair company in an easily accessed location. This will help immensely in the event of any roof or siding damages that occur from the storm.
Ice Storms: Why They’re So Dangerous and How to Stay Safe
Even a thin coating of ice can result in a travel nightmare, while heavier amounts will severely damage trees and power lines. Strong winds can add extra force to already weighed down tree branches and power lines, increasing the likelihood of significant damage.
Ice Storm Facts
- Ice can increase the weight of branches by 30 times.
- A 1/2-inch accumulation on power lines can add 500 pounds of extra weight.
- An ice storm in 2009 centered from northern Arkansas to the Ohio Valley knocked out power to 1.3 million.
- In 1998, an ice storm in northern New York and northern New England damaged millions of trees and caused $1.4 billion in damage. Accumulations were as much as three inches thick!
These ice accumulations are caused by freezing rain. Freezing rain is a result of snow falling through an above-freezing warm layer in the atmosphere above the surface of the earth, which melts the snowflakes into rain. The rain drops then move into a thin layer of below-freezing air right near the surface of the earth, allowing them to freeze on contact to the ground, trees, cars and other objects.
What kind of damage do different amounts of ice cause? Below we define the impacts of nuisance, disruptive and crippling ice storm events.
Nuisance Ice Storm
A nuisance event is usually one of less than a 1/4 inch of ice.
Even though these lighter accumulations are considered nuisance, travel can be extremely dangerous even with a light glazing.
Disruptive Ice Storm
A disruptive ice storm is typically one of 1/4 to 1/2 inch of ice accumulation.
This amount of ice starts to damage trees and power lines.
Crippling Ice Storm
Widespread accumulations of over 1/2 inch.
With this much ice there is severe tree damage and power outages may last for days.
The most devastating storms contain ice accumulations of an inch or more.
- Avoid driving on icy roads for your safety and the safety of emergency personnel.
- Be sure to charge cell phones and laptops ahead of time. Make sure you have several ways to communicate with others. Consider landline phones, social media, and texting.
- Remember, if it’s too cold for you, it’s too cold for your pets. Plan for pets to come inside, and store adequate food and water for them.
- Children should never play around ice-covered trees; they may be injured if a branch breaks under the weight of the ice and falls on them.
- Think about safe alternate power sources you could use if you lose heat, such as a fireplace, wood/coal stove or portable space heaters. However, be sure to exercise caution:
- Follow manufacturers instructions when using portable space heaters and other devices.
- Never use portable generators, camp stoves and grills inside your home or garage; they should only be used outside. Keep them at least 20 feet away from your home’s windows, doors and vents to prevent deadly carbon monoxide poisoning.
- Use flashlights during power outages instead of candles to prevent the risk of fire, and keep plenty of extra batteries on-hand.
Before the Power Goes Out: Food Safety
- Make sure you have appliance thermometers in your refrigerator and freezer.
- Check to ensure that the freezer temperature is at or below 0 degrees and the refrigerator is at or below 40 degrees.
- In case of a power outage, the appliance thermometers will indicate the temperatures in the refrigerator and freezer to help you determine if the food is safe.
- Freeze containers of water for ice to help keep food cold in the freezer, refrigerator, or coolers in case the power goes out. If your normal water supply is contaminated or unavailable, the melting ice will also supply drinking water.
- Have coolers on hand to keep refrigerated food cold if the power will be out for more than four hours.
- Purchase or make ice cubes in advance and store in the freezer for use in the refrigerator or in a cooler. Freeze gel packs ahead of time for use in coolers.
- Store food on shelves that will be safely out of the way of contaminated water in case of flooding.
When the Power Goes Out: Food Safety
- Keep the refrigerator and freezer doors closed as much as possible to maintain the cold temperature.
- The refrigerator will keep food cold for about 4 hours if it is unopened.
- A full freezer will keep the temperature for approximately 48 hours (24 hours if it is half full) if it is unopened.
- Buy dry or block ice (or freeze containers of water) to keep the refrigerator as cold as possible if the power is going to be out for a prolonged period of time.
- If you plan to eat refrigerated or frozen meat, poultry, fish or eggs while it is still at safe temperatures, it’s important that each item is thoroughly cooked to the proper temperature to assure that any foodborne bacteria that may be present is destroyed. However, if at any point the food was above 40 degrees for two hours or more — discard it.
- For infants, try to use prepared, canned baby formula that requires no added water. When using concentrated or powdered formulas, prepare with bottled water if the local water source is potentially contaminated.
