Meeting hail must definitely remember this knowledge

According to a warning from the meteorological agency, hail is a dangerous extreme weather phenomenon and only gradually decreases when the rainy season comes, ie around the end of May.

People can identify hail prepared to occur based on a few characteristics such as: There are strong thunderstorms, dark clouds in the sky; at night there was thunder, the wind was blowing all of a sudden, it was suddenly cold .

If you see that the sky is windy, dark clouds cover the sky almost closed, and then wind up, create a "buzzing, rumbling" sound constantly, be wary of hail. If it then sprinkled a few rainstorms, it felt like the air temperature was very cold and the hail had come. Everyone needs to find a safe place for me.

To minimize damage when hail may fall unexpectedly, keep in mind the following:

1. If you are going out on the street and have a hail, you should immediately stop looking for a hidden place, wear a helmet to avoid falling rocks, waiting for the stones on the melted road to continue to avoid slipping. For large rocks with hailstones, people should find places where they can "hide" like a table, under a bed, find hard objects to cover their heads.
2. With the roof , regularly check the condition of the roof and reinforce the roof. In critical areas, materials that can withstand impact should be used. Roof frame system, purlin should also use good bearing, corrosion resistant, reinforced materials. Construction materials and techniques can improve the rigidity of the roof frame and help reduce damage caused by hail.
3. Making the roof slopes down to the sides: How to build this roof will reduce the impact from hail. Hail hitting the roof at an angle of 90 degrees will cause more damage than hail falling on the roof at an angle of deviation.
4. For cars , it is necessary to put in a solid garage and garage. If there is no garage, garage will be equipped with gas tarpaulin, which is a set of accessories including waterproof car tarpaulin with air blowing space to turn into protective air mattress, powered by car power or battery Reserve. When gas pump is not activated, tarpaulin can be used to cover the sun and rain as usual.
   
   For crops or crops that are easily crushed, you can set up a trellis along the beds, and should make triangular trusses that will help reduce the impact of hailstones when colliding, rocks will fall on either side of the bed without piercing the cover, pay attention to making sure it is secure.

In addition to the above danger, hail can also bring other hazards such as carrying toxins, acid . If the cloud is formed from toxic waters, the environment is not clean, the dirt in the water Rain can damage human skin, cause allergies, so before using water contaminated with ice storms, people should take water samples, bring them to centers to check water quality.
