Winter Health Tips
- When your extremities, such as fingers, toes, ear lobes, or nose, become numb or pale, take steps to prevent frostbite.
- The symptoms of hypothermia are extreme chill, amnesia, loss of sense of direction, slurred speech, and extreme fatigue. If you experience such symptoms, immediately go to the hospital.
- A sudden decline in temperature might worsen existing health conditions related to the heart or vascular system, respiratory system, nervous system, or skin disease. Therefore, households with infants and children or elderly family members must carefully maintain the heating system.
- People with high blood pressure or heart disease must make sure to keep exposed body parts warm, particularly the head.
Wash your hands and feet when you come home. Be careful not to become exhausted through excessive drinking or long hours at work. People with diabetes or chronic pulmonary diseases must get flu shots.
- Wash your hands and feet when you come home. Be careful not to become exhausted through excessive drinking or long hours at work. People with diabetes or chronic pulmonary diseases must get flu shots.
- If you have frostbite, take off your shoes or clothes and keep the affected body parts warm. Make sure to wash and dry the affected area(s).
- If you plan to drive a long distance, first check the weather reports and road conditions in order to avoid accidents.
Winter Exercise Warnings
- Stretch before exercising to relax your joints and muscles and prevent injuries.
- Also, prep and warm up indoors before exercising outside.
- Exercise indoors, if possible, to reduce the risk of injury.
- Wear layers of clothes, but not too many.
- People with chronic conditions, such as high blood pressure, should work out indoors in the afternoon.
- Around 10 to 15% more energy is consumed to maintain your body temperature in the winter. Therefore, you should keep your exercise intensity to about 70 to 80%.
- As alcohol causes the body temperature to drop, through diuretic and respiratory effects, refrain from drinking when hiking, skiing, or playing other winter sports.
- After a work out, wash with warm water, change into clean clothing, and keep warm to avoid catching a cold.
Keeping the Water Gauge and Plumbing Warm
- Pack the inside of the water gauge protection box with old clothes and seal it from the outside with tape to keep cold air from seeping in.
- In apartment buildings with long hallways, water gauges often freeze and break, therefore pay careful attention to keep your water gauge warm.
- When leaving the house empty for a long time, allow a trickle of water to run continuously to prevent the pipes from freezing.
- Install thermal insulation for exposed water pipes in yards or bathrooms.
- If your water pipes freeze, thaw them gradually with lukewarm water (below 50℃).
Keeping the Boiler Pipes and Tubes Warm
- Keep the exposed pipes under the boiler warm by wrapping them in old clothes, etc.
- Keep a trickle of warm water running when leaving the house empty for a long time to prevent the pipes from freezing.
- If your water pipes freeze, thaw them gradually with lukewarm water or a blow dryer.
When Going Out
- Use public transportation, if possible.
- When driving, go out during the day and avoid going unaccompanied, if possible.
- Inform your family of your destination and schedule in advance.
- Use main roads whenever possible and avoid taking short cuts or side streets.
- When trapped in a vehicle
Contact emergency rescue services using any means possible.
If there are other passengers, stay warm together using body heat.
Take turns napping. One person needs to be awake at all times so as not to miss an opportunity for rescue.
Keep the light on inside the car at night so that rescue workers may locate you more easily.
Place colorful clothes on the snow so that rescue workers and aircraft can find you more easily and quickly.
Safety Measures When Driving
- Take appropriate winter safety driving measures, such as using snow chains when there is ice or snow on the road. Keep the seat high and the windshield free of frost to maximize your field of vision and ready yourself for any unexpected accidents.
- When accelerating from rest on a slippery road, use second gear and the half clutch method. Keep the front wheels straight to prevent spinning.
- When stopping on an icy road, first use the engine brake to slow down, and then step on the brake pedal to come to a stop.
- Drive slower than usual and leave adequate space between your vehicle and the vehicle in front of you.
- Keep snow chains, salt, shovels, and other tools in your vehicle. Also, make sure to check the antifreeze, battery, and oil in advance.
Agricultural and Forestry Sectors
- Keep grains, vegetables, and fruits at appropriate temperatures, and take measures to prevent greenhouse plants from freezing.
- Install double-doors in greenhouses, and on the northern wall, install an insulating wall and a wind break wall.
- Install insulation or additional layers around the greenhouse.
- Prepare emergency insulation materials in case of power outages that render the heating system inactive.
- Keep heating equipment in good condition in case of a sudden sharp decline in temperature.
- Check water pipes in advance to prevent freezing.
- Make sure to always check the weather reports so that you may prepare for and prevent damage from cold waves.
Refrain from excessive use of electric heaters and do not place any inflammable materials near the heaters.
- When using an electric heater in a large-scale apartment complex, prevent the overloading of power transformers by turning the heater off for 15 minutes for every hour of use.
- Refrain from plugging multiple devices into one electrical outlet.
- Do not attempt to use damaged electrical devices. Instead, contact the Korea Electric Power Corporation or Korea Electrical Safety Corporation.
- Always use genuine fuses, not copper wire or other fabrications.
- Do not put the gas tank in hot water or heat it to check the remaining amount of gas.
- Syphon tanks for LPG (containers that can supply LPG in both gaseous and liquid states) must only be used in facilities installed with a carburetor.
- Before using a gas boiler, check to see if there are any blockages in the vents or exhaust stacks.
- Perform frequent inspections of hoses and pipe joints to prevent gas leaks.
- To prevent pipes from freezing due to sudden drops in temperature, remove some water and add antifreeze.
- Take measures to keep facilities warm, thereby preventing the release of hazardous substances, fires, explosions, or gas poisoning from frozen or broken equipment.
Regional Heating Facilities
In regional heating facilities, please check:
- The status of maintenance and protection of facilities, in order to prepare for any freezing or breakages in the winter;
- The operational status of recovery equipment, in order to prevent damage from snow or freezing, and;
- The status of automatic fire detectors.
- NOT close the valves of the heating and hot water system for individual apartments, in order to prevent the pipes from freezing.
- Have broken thermostats repaired or replaced. While waiting for the thermostat to be serviced, the temperature can be adjusted using the heating and hot water system.
- Open the valve to completely remove the air from the heating pipes.
- To maintain a proper temperature, the windows and openings of the elevator machine room should be checked for any damage. Any damaged windows or openings should be repaired or replaced immediately.
- The waterproof conditions of the “pit (the bottom-most portion of the elevator shaft)” should be checked and, if necessary, repairs should be carried out.
- Refrain from cleaning the elevator or the surrounding areas with water, as dangerous icy surfaces may be formed.
- When using the elevator for the first time after a long period of disuse, be sure to carry out test runs and thoroughly check the safety conditions of the elevator.
