Extended information

The impact of meteorology on industrial production is very extensive. Whether it is the selection of the factory site, the design of the building, or all aspects of raw material storage, manufacturing, product storage and transportation, they are all affected by meteorological conditions such as temperature, humidity, pre cipitation, wind, and insolation.

Especially disastrous weather, such as tropical storms and typhoons, heavy rains and floods, interruption of transmission lines or damage to factories and equipment, flooded warehouses, casualties of workers, and inability to go to work; insufficient water supply caused by drought; lightning, etc. Causing fires; freezing and cracking of water pipes and oil pipelines and other freezing damage caused by low temperature; high temperature and low humidity can easily induce fires and explosions; high temperature and high humidity can easily cause corrosion and mildew of raw materials, etc., as well as affect the health and production efficiency of workers, etc., which directly or Indirectly affects industrial production.

There are more work-related injuries in high-temperature seasons than in other seasons; when the temperature and humidity in the cotton spinning mill workshop suddenly drop, cotton yarn breaks increase.
