What protective measures should be taken in case of snowstorm and hail weather?

The main hazards of blizzard include obstructing the safety of traffic, communication and transmission lines; Crops are frozen, leading to agricultural failure or serious reduction in production, which has an adverse impact on vegetable production and supply; With the low-temperature freezing injury, the elderly and livestock are frostbitten or frozen to death, resulting in road ice accumulation, which leads to frequent traffic accidents and pedestrians falling or being injured. Therefore, its emergency points and protective measures include:

-The temperature drops suddenly, so keep up with the disease prevention. Blizzard is often accompanied by a drop in temperature, which easily leads to the relapse of the elderly, the weak, the sick and the disabled, especially the sudden drop in temperature is easy to aggravate respiratory and cardiovascular diseases, and disease prevention cannot be ignored.

-melting snow, beware of freezing. After the blizzard, clear the snow on the road surface in time, or sprinkle snow melting substances such as salt and charcoal ash on the road surface to prevent the road surface from freezing.

-There is snow on the road and the traffic is slow. In snowstorm weather, drivers need to drive carefully, try to slow down and avoid sharp turns; Don't brake too fast and too hard to prevent sideslip.

-Set up signs quickly in case of accidents. In the event of a traffic accident in a snowstorm, eye-catching signs should be set up not far from the scene of the accident immediately to avoid the recurrence of the accident.

-Safety first, close the traffic. When the snowstorm seriously affects visibility or causes roads to freeze, planes can be suspended from taking off and landing, trains can be stopped, and expressway can be temporarily closed.

-suspension of classes, cold and antifreeze. When the snowstorm causes the snow to be too deep or the weather is cold, you can notify the school to suspend classes and the relevant industrial and mining production units to suspend business (except for special industries).

When a snowstorm happens, accidents often happen because the ground is wet and it is difficult to go. For the sake of safety, residents had better choose to travel by bus instead of driving.
