Niigata Prefecture, Japan, was hit by heavy snow. What should I do if the snow did not reach the roof?

Recently, many places in Japan suffered from heavy snow, which seriously affected the local people. The snowfall started on the 7th, which had a serious impact on Niigata Prefecture, Fukui Prefecture and Toyama Prefecture in Japan. Among them, Niigata Prefecture is the most seriously affected, and the snow has not passed the roof. Three people have been killed and 112 others have been injured.

The most commonly used methods for dealing with snow are as follows:

1. Sprinkling salt

Under normal circumstances, the roof can be directly exposed to sunlight, and the snow will melt with the sunlight. However, because the newly fallen snow is crisp, like cotton, it can store the heat of the sun and melt quickly, and the first melted snow turns into water, which makes the snow below frozen, not crisp and loose, and it is difficult to store the sun.

Second, raise the indoor temperature

As a superstructure to protect the house, the roof effectively resists the damage of the upper snow to the lower floors, but because it exists above, we can transfer the heat to the roof by raising the indoor temperature (as we all know, hot air flows upward), and the temperature rise inside the roof helps to melt the snow outside the roof.

Third, wait for natural melting after reinforcement

In the case of a large amount of snow, it may threaten the safety of the house itself. In this case, it is very dangerous to melt snow blindly. Therefore, we should change our thinking, first reinforce the load-bearing part of the house, and then wait for the natural melting of the snow or regularly remove a small amount of snow under the condition of ensuring that the house is reinforced to withstand a large amount of snow. Never rashly clean up the snow. Before cleaning, it should be determined according to the roof bearing capacity of the proposed building. The purpose of cleaning is to prevent injury accidents caused by roof collapse and ensure the safety of houses and property inside. When it is really necessary to organize personnel to clear the snow. First of all, the problem of roof load should be fully considered to prevent the house from collapsing due to the increase of load when people go up to the roof to clear the snow, resulting in accidental injuries.
