Winter Safety Awareness Week November 11th-17th, 2018...Are You Winter Ready???

• Keep ahead of advancing winter weather by listening to NOAA Weather Radio.
• An ice storm will take down power lines knocking out electricity. Check battery powered equipment before the storm arrives.
• Check your food and stock an extra supply. Include food that requires no cooking in case of power failure. If there are infants or people who need special medication at home, make sure you have a supply of the proper food and medicine. Make sure pets and animals have shelter and a water supply.
• If appropriate, check your supply of heating fuel. Fuel carriers may not be able to reach you due to closed roads.
• Be careful when using fireplaces, stoves, or space heaters. Proper ventilation is essential to avoid a deadly build-up of carbon monoxide. Don't use charcoal inside as it gives off large amounts of carbon monoxide. Keep flammable material away from space heaters and do not overload electric circuits.
• Dress for the conditions when outdoors. Wear several layers of light-weight, warm clothing: layers can be removed to prevent perspiring and subsequent chill. Outer garments should be tightly woven, waterproof and hooded. For the hands, mittens, snug at the wrists, offer better protection than fingered gloves.
•  Don't kill yourself shoveling snow. It is extremely hard work for anyone in less than prime physical condition. It can bring on a heart attack, a major cause of death during and after winter storms.

Extreme cold temperatures are a big danger during winter months. Prolonged exposure to the cold can cause frostbite, hypothermia, or in extreme cases death. In fact, excessive cold is one of the leading weather-related causes of death across the country. Infants and the elderly are most susceptible to extreme cold. Freezing temperatures also cause damage to crops and property.

Frostbite occurs when the skin becomes cold enough to actually freeze. A loss of feeling and a white or pale appearance in extremities, such as fingers, toes, ear lobes, or the nose are symptoms of frostbite.

Hypothermia (Low Body Temperature) can occur during long periods of exposure when the body temperature drops below 95 degrees F. A person will become disoriented, confused, and shiver uncontrollably, eventually leading to drowsiness and apparent exhaustion. In severe cases, death is possible.

Wind Chill is the term used to describe the rate of heat loss on the human body resulting from the combined effect of low temperature and wind. As winds increase, heat is carried away from the body at a faster rate, driving down both the skin temperature and eventually internal body temperature. While exposure to low wind chills can be life threatening to both humans and animals alike, the only effect that wind chill has on inanimate objects, such as vehicles, is that is shortens the time it takes the object to cool to the actual air temperature (it cannot cool the object below that temperature). For example, water freezes at 32 degrees F, regardless of what the wind chill temperature is. 

The current wind chill temperature index (WCT) formula was developed during 2000 -2001 and implemented for the winter of 2001-2002. A Joint Action Group for temperature Indices (JAG/TI) consisting of the NWS, Meteorologic Services of Canada (MSC), the academic research community (Indiana University-Purdue University in Indianapolis (IUPUI), University of Delaware, and University of Missouri), and the International Society of Biometeorology, developed the formula. The JAG/TI formula made use of the advances in science, technology, and computer modeling to provide a more accurate, understandable, and useful formula for calculating the dangers from winter winds and freezing temperatures. In addition, clinical trials were conducted and the results of those trials have been used to verify and improve the accuracy of the new formula. 

Standardization of the WCT Index among the meteorological community is important, so that an accurate and consistent measure is provided and public safety is ensured. Some of the items incorporated into the WCT include:

• used wind speed calculated at the average height (5 feet) of the human body’s face instead
  of 33 feet (the standard anemometer height)
   
• based on a human face model
   

• incorporated modern heat transfer theory (heat loss from the body to its surroundings,
  during cold and breezy/windy days) 

• lowered the calm wind threshold to 3 mph 

• used a consistent standard for skin tissue resistance; and 

• assumed the worst case scenario for solar radiation (clear night sky). 

Severe winter storms can cut off your supply of electricity and other winter fuels. It is important to have an alternative heat source available. However, be extremely careful in using fireplaces or wood stoves. Make sure they are properly ventilated to avoid the build up of carbon monoxide, an odorless, colorless, and deadly gas. Do not use charcoal indoors as it gives off large amounts of carbon monoxide. Have your furnace checked before the weather gets cold to make sure it is in good working order. Using alternative heat sources can also be a fire danger. Be very careful because if conditions are bad, the fire department may not be able to get to you. Make sure your smoke alarms are working and have fresh batteries. It is also a good idea to have carbon monoxide alarms in your home adjacent to sleeping areas. 

Portable electric generators like the one pictured above have become very popular. They can be an excellent piece of equipment to have should you lose electric power for an extended period of time. However they must be used safely and properly. A small generator can usually only run one major appliance at a time. It is also very important to place the generator OUTSIDE! The exhaust from the engine emits deadly carbon monoxide gas. Make sure you read the manual carefully and follow all the recommended safety precautions.

Children can be especially susceptible to the dangers associated with winter weather. Their youthful enthusiasm often takes over when common sense should prevail.

School administrators and principals need to be sensitive to the dangers winter weather can pose to children and be prepared. Winter weather procedures and practices need to be established before the onset of winter cold. The following items should be considered when formulating a winter weather safety plan:

• All schools should have ready access to current weather information. Whether you use the local media, the Internet, or NOAA Weather Radio, it doesn't matter. The idea is to stay informed of the latest forecast. School administrators are encouraged to establish a working relationship with their local NWS office, so if necessary, they can be briefed on the latest forecast. 
• All schools need to have a plan in regard to closures due to snow, ice, or extreme cold.
• During the winter months, guidelines need to be established regarding outside recess. Temperatures and wind chills need to be monitored and criteria set as to when outside recess will be allowed.
• School bus drivers should receive extra training on driving during winter weather. Snow and ice can often accumulate quickly and unexpectedly on roads creating dangerous driving conditions.
• With many households having two working parents today, it may be necessary for some children to be brought to school early. Schools should make provisions to allow children inside school buildings as early as possible during cold weather.

Unfortunately many people turn to using devices not designed for use as a supplemental heat source thereby placing themselves and others in life threatening situations. It is important to maintain fire safety awareness throughout the winter. Too many preventable fires occur year-round, especially during the winter months. During this time you should examine heating methods, practice fire escape plans and check smoke detectors. Fires related to home heating are primarily responsible for the increased number of fires during the winter.

Fire safety officials stress the importance of ensuring a home has working smoke and carbon monoxide alarms and testing them monthly to ensure they’re in working order. The advance warning these alarms provide can prevent tragedy by giving families enough time to get out of their house alive.

All gasoline and diesel generators create carbon monoxide, a colorless, odorless, tasteless gas that inhibits the body’s ability to absorb oxygen, a condition that can cause serious health problems, and even death, within a matter of minutes. The first symptoms of carbon monoxide poisoning usually include headache, lightheadedness, dizziness and unexplained sleepiness.

Tips for winter storm fire safety:
• Use battery operated lanterns or flashlights instead of candles and oil lamps during power outages.
• Keep generators outside of occupied buildings and never run a generator in an attached garage.
• Never use fossil fueled (propane, kerosene or heating oil) space heaters in an enclosed room; these heaters require a well ventilated area to prevent the accumulation of carbon monoxide.
• Keep chimneys, fireplaces and flues clean and never use a liquid fuel or cardboard to start a fire in a woodstove or fireplace.
• Do not use extension cords to power electric space heaters or use any electric heater that has the cord frayed, repaired or improperly replaced.
• Vehicle exhaust fumes contain large quantities of carbon monoxide. Never run a vehicle in a garage. If you are stuck in a vehicle, make sure the exhaust pipe is clear of snow, ice or debris and only run the engine for short periods to maintain warmth in the vehicle.

• Your automobile can be your best friend or worst enemy during winter storms. Get your car winterized before winter arrives. The following items should be checked; ignition system, cooling system, fuel system, battery, lights, tires, heater, brakes, wipers, defroster, oil, exhaust. Keep water out of your fuel tank by keeping it full.
• If you travel often during winter, carry a winter storm kit in you car. It should include; flashlight, windshield scraper, paper towels, extra clothes, matches/candles, booster cables, compass, maps, sand, chains, blankets, high calorie non-perishable food.
•  Winter travel by car is serious business. If the storm exceeds or tests your driving ability, seek available shelter immediately.
• Plan your travel. Try not to travel alone and drive in convoy when possible.
• Drive carefully and defensively. Pump your brakes when trying to stop on snow or ice covered roads.

Severe winter weather can strand you in your own home. It is a good idea to keep some extra supplies around during the winter season. Items you may want to have include non-perishable food, medical supplies, batteries, and emergency heating supplies.

Working in cold weather puts a tremendous strain on the body, even for people in good shape. Take frequent breaks and don't overexert yourself. Make sure you dress properly for the conditions. Wear several layers of lightweight clothing. Air is trapped between the layers to help keep the body warm. Protect the extremities, such as the hands, feet and ears as they are the most susceptible to frostbite. Wear a hat as a large percentage of the body's heat is lost through the top of the head.
