Changchun, Jilin issued an orange warning of cold wave. What should we pay attention to in the face of cold wave?
What should I pay attention to when the cold wave strikes?
First, defend in time and prepare for the cold.
When traveling in snowy days, you should take the sidewalk instead of the motorway to avoid being hit by a slipping car; Don't walk too fast. You'd better wear non-slip shoes or sports shoes instead of hard plastic shoes. If you suddenly fall, try not to support the ground with your wrists, because this falling posture is the most likely to cause arm fractures.
Once you fall and break, don't rub around. Fix the fracture site with scarves, books and other tools, ask others for help, and go to a nearby hospital for treatment immediately. Save yourself after falling, and check where you fell. Generally, fractures after snow are mostly concentrated in ankle, coccyx and lumbar spine. Experts suggest that don't rush to get up after falling, first look at whether you hurt your thigh, waist or wrist. Generally, the thighs and wrist fracture are light, and people can hardly move;
If you have back pain, don't walk around at will, because if you walk around at will after lumbar fracture, it is likely to cause joint dislocation, and in severe cases, it may lead to paralysis of lower limbs. At this time, you should call for help as soon as possible. The rescuer should not carry the injured person on his back at will, but should use a hard board to carry the injured person to the hospital, or call 120 to seek emergency assistance from professional medical staff.
Ride a bicycle or electric car in snowy days, and check whether the brakes are out of order before going out; Drive at a low speed after going on the road; Don't ride a bike on the floor tiles that are easy to freeze and slide; Don't grab the road with motor vehicles, so as not to be injured by sideslip motor vehicles; On roads with thick snow or thin ice, it is best to get off and walk. Once you fall and break, don't rub around. Fix the fracture site with scarves, books and other tools, ask others for help, and go to a nearby hospital for treatment immediately.
Second, driving in snowy days:
1, the road surface is slippery after snow, and the temperature is high during the day, so the ice and snow on the road are easy to melt, and the ground may be formed when it meets low temperature at night? Ground armor piercing? Pay special attention when traveling. Novices should avoid driving.
2. Before driving in snowy days, be sure to clear the snow on the windshield, headlights and reflectors to ensure a clear line of sight and a wide field of vision; When starting on a snowy road, move back and forth slightly so that vehicles can enter the driveway smoothly.
3. In the driving process, the friction coefficient is extremely small, whether in the snow-covered area or on the ice, and the wheels are prone to slip, sideslip, idling, out of control of direction, and increased braking distance. And careless operation is prone to traffic accidents. Therefore, driving in snowy days should be slow first, and then keep enough distance from the car in front. Pay attention to the front and three rearview mirrors when driving, and pay attention to the vehicles on both sides. When driving in slip roads, auxiliary roads and other places, you should pay attention to avoiding cyclists and pedestrians, and always be prepared to take braking measures in advance.
4, when braking, don't step on the brake pedal, should gradually hard. Don't step on the brakes. Putting the first brake can reduce the speed faster with the help of engine deceleration.
5. Roads in suburbs and mountainous areas are easy to freeze, so drive carefully, control the speed, find out the road conditions in advance and take measures in advance. When going uphill and downhill, you should use the first gear to pass smoothly, and it is not advisable to shift gears in the middle. Anti-flameout when going uphill, and no neutral taxiing when going downhill.
Third, heating safety.
In winter, the weather is dry and things are dry, which is prone to fire. Remind residents and friends to pay attention here. Do not pull wires indiscriminately, do not overload electricity, do not use inferior household appliances, use fire and electricity without leaving people, and be sure to cut off the power supply and gas pipeline valves when going out. If you find a fire hazard, you should call 1 19 to report it to the fire department in time.
Four, water meter antifreeze
1、? Dress and wear a hat? . Exposed water supply pipes, faucets and other water supply facilities must be wrapped with cotton and linen fabrics, plastic foam and other insulation materials. Outdoor water meter wells should be filled with sawdust, cotton wool or other thermal insulation materials, masks should be covered with plastic sheets, and the cover of water meter box should be covered, which can effectively prevent water meters and gate valves from freezing. When installing a water meter in the corridor, we should also pay attention to closing the corridor door.
2、? Drip into a line? . In cold weather, you can unscrew the faucet slightly at night to drip into a line to ensure the flow of tap water in the pipeline, which can effectively prevent the pipeline from freezing. The dripping water can be collected in a suitable container to save water.
3、? Close the doors and windows? . In cold weather, especially at night, rooms with water supply facilities such as balconies, kitchens and bathrooms should close their windows to ensure that the indoor temperature is above zero degrees Celsius.
4、? Evacuation facilities? . If you are away from home for a long time, you can turn off the valve on the water meter before you leave home and drain the tap water in the pipeline. The water pipes of solar water heaters should be equipped with vertical anti-freezing drainage devices, and the water in the water tanks should be drained in time in ice and snow days to prevent the water heaters from freezing. Users who use secondary water supply should cover the top cover of the water tank and wrap the upper and lower pipes and valves of the water tank tightly with thermal insulation materials.
5. For frozen faucets, water meters and pipes, it is advisable to wrap hot towels on the faucets first, then pour warm water to thaw the faucets, then unscrew the faucets and slowly inject water with warm water along the faucets to thaw the pipes. If there is still no water flowing out of the water meter, it means that the water meter is frozen. At this point, wrap a hot towel on the water meter and pour warm water (not higher than 30 degrees Celsius) to thaw the water meter. Don't shower with hot water or bake with fire, otherwise it will damage the water meter.
