Safety tips
Check the Forecast
Make checking the forecast part of your regular routine so you'll know when to expect cold weather.
Adjust Your Schedule
If possible, adjust your schedule to avoid being outside during the coldest part of the day, typically the early morning.
Protect Your Pets, Livestock and other Property
If you have pets or farm animals, make sure they have plenty of food and water, and are not overly exposed to extreme cold. Take precautions to ensure your water pipes do not freeze. Know the temperature thresholds of your plants and crops.
Dress for the outdoors even if you don't think you'll be out much.
In power outages:
Wear layers of loose-fitting, lightweight, warm clothing as well as hats, mittens, and blankets.
Close blinds or curtains to keep in some heat.
Close off rooms to avoid wasting heat.
Place towels or rags in cracks under doors.
Practice portable generator safety
use outdoors, at least 20 feet away from doors/windows/garages to avoid carbon monoxide poisoning. Follow instructions on proper use.
Once your family is safe, check on your neighbors and the vulnerable to make sure they are okay.
After extreme cold:
Check Your Pipes
Your pipes may be frozen. Water pipes on exterior walls and in places that are subject to cold, like in the basement, attic, and under kitchen cabinets, freeze most often. Water expands as it freezes, causing pipes to burst. If they are frozen, first turn on the faucet. Water will drip as you warm the pipes. Heat the pipes using a space heater, heating pad, electric hair dryer, or hot water on a cloth. Never use an open flame. Continue until water pressure returns to normal or call a plumber if you have more issues.
Salt Your Walkways
Once it warms up enough to go out, it's important to shovel the snow from your sidewalks and driveway or sprinkle salt if there is ice. If there is a thick layer of snow on the ground that you cannot move, salt the area so that the snow melts. You should also put down salt if there is ice on the stairs leading into your house.
Call Your Neighbors
Check to see that your neighbors are okay, particularly seniors, disabled persons, or others living alone. Carbon monoxide poisoning is one of the leading causes of death after extreme cold, particularly if there are power outages. Cases of frostbite and hypothermia are also common for elderly people who were stuck in their homes.
Refill Your Supplies
This cold event may be over, but there might be another one soon. It is important to always be prepared.
If you plan to drive:
Fill up the tank
Make sure your car or vehicle has at least a half a tank of gas during extreme cold situations so that you can stay warm if you become stranded.
Update Your Winter Car Survival Kit
Make sure your car survival kit has the following:
Jumper cables: flares or reflective triangle are great extras
Flashlights: Replace the batteries before the winter season starts and pack some extras
First Aid Kit: Also check your purse or bag for essential medications
Baby, special needs gear: If you have a baby or family member with special needs, pack diapers and any special formula or food
Food: Stock non-perishable food such as canned food and a can opener, dry cereal and protein rich foods like nuts and energy bars
Water: Have at least 1 gallon of water per person a day for at least 3 days
Basic toolkit: Pliers, wrench, screwdriver
Pet supplies: Food and water
Radio: Battery or hand cranked
Cat litter or sand: For better tire traction
Shovel: To dig out snow
Ice scraper: Even if you usually park in a garage, have one in the car.
Clothes: Make sure you dress for the weather in warm clothes, gloves, hat, sturdy boots, jacket and an extra change of clothes for the cold
Warmers: Pack extra for body, hands, feet
Blankets or sleeping bags: If you get stranded in traffic on a lonely road, you'll be glad to have it.
Charged Cell Phone: Keep a spare charger in your car as well
Hazard information
If you or a loved one needs to go outside during extreme cold this winter, it's important to dress in layers. Ensure exposed skin is covered to minimise the risk of frostbite or hypothermia. Try to shield yourself from the wind as much as possible. Once back indoors, immediately change into dry clothes if you are wet. Be vigilant for signs of frostbite and hypothermia, and act swiftly upon noticing any symptoms.
Watch for Frostbite
Frostbite can develop within minutes, particularly on extremities such as fingers, toes, nose, and ears, although it can affect any exposed skin area. If you suspect frostbite, promptly move indoors to a heated environment and warm the affected areas using warm water or body heat—avoid hot water or direct heat sources like fireplaces as they may cause burns. Seek medical help for severe cases of frostbite.
Frostbite occurs when the body's survival mechanisms activate during freezing weather. Circulation to extremities reduces to protect vital organs, leading those parts to eventually freeze. To prevent frostbite, stay indoors in extreme cold, especially when the windchill drops below -50°F. If you must go outside, cover every part of your body including ears, nose, toes, and fingers; mittens are preferable to gloves. Keep your skin dry and avoid the wind when possible. Stay hydrated as fluids boost blood volume, which helps prevent frostbite. Avoid caffeine, alcohol, and smoking, as caffeine constricts blood vessels, alcohol reduces shivering, and smoking restricts blood flow to the hands.
Signs & Symptoms of Frostbite:
Redness or pain in any skin area, which may be the initial sign
White or grayish-yellow skin areas
Skin that feels unusually firm or waxy
Numbness
Frostbite First Aid:
Get indoors as soon as you can. Until then:
Avoid rubbing or massaging cold body parts.
Place hands in armpits.
Hold onto another person or animal.
Drink warm liquids.
Add extra layers of clothing, blankets, etc.
Remove rings, watches, or other tight jewellery.
Once inside:
Do not walk on frostbitten feet to avoid further damage.
Take a warm (not hot) bath and wrap your face and ears in a warm, moist towel.
Stay away from hot stoves or heaters and avoid using heating pads, hot water bottles, or hair dryers to prevent burns before sensation returns.
Frostbitten skin will become red, swollen, and feel like it's burning; blisters may form, but do not break them to avoid scarring and infection.
Immediately seek medical help if the skin becomes blue or gray, very swollen, blistered, or remains numb.
Beware of Hypothermia
Hypothermia occurs when the body temperature drops below 95°F, presenting a serious hazard. Seek medical assistance at once. Move the person indoors to a heated area and warm the body's core first. Administer CPR if the individual is unconscious.
Hypothermia can set in at temperatures as high as 60°F, especially in water or with prolonged exposure without appropriate clothing. The CDC reports around 1,300 annual deaths due to hypothermia, predominantly among seniors, although children and young adults are also at risk. Factors such as certain medications, circulatory issues, and specific health conditions can increase vulnerability to hypothermia. As people age, their bodies become less efficient at detecting cold and shivering.
Preventive Tips for Hypothermia:
Dress in layers.
Ensure good insulation against the cold.
Minimise exposure to indoor drafts.
Consume nutritious food and wear warm attire.
Wear a hat in cold weather.
Eat hot meals and drink warm beverages regularly.
Arrange for regular check-ins from family or neighbours if living alone.
Consult with a doctor regarding medications that might heighten your hypothermia risk.
If experiencing a body temperature of 95°F or lower, feeling sluggish or mentally foggy, seek medical help immediately. It's better to be cautious than risk a potentially fatal condition.
In an emergency, call an ambulance and lay next to the person under thick blankets to share body heat. Avoid rough handling or rubbing the person.
Staying Safe During Power Outages
Wear multiple layers of loose-fitting, lightweight clothing along with hats, mittens, and blankets. Close blinds or curtains to retain heat and block off unused rooms to conserve warmth. Place towels or rags under doors to prevent drafts. Follow safety guidelines for portable generators: use them outdoors and keep them at least 20 feet away from doors, windows, and garages to avoid carbon monoxide poisoning. After ensuring your household is safe, check on neighbors and vulnerable individuals to make sure they are secure.
