Seat belts are essential protective equipment for aerial work. It is understood that in the industrial production process, the rate of casualties caused by human fall is high. The statistical analysis of human casualty accident casualties accounted for about 15% of accidents. Fall accidents at high altitudes are related to many factors, such as human factors, physical factors, environmental factors, management factors, working heights, etc., and the main ones are closely related to the height of operations. According to statistical analysis of fall accidents at high altitudes, accidents involving over 5m fall accidents account for about 20%, and those below 5m account for about 80%. Most of the former are fatal accidents. This shows that it is necessary to prevent falling from high places and take personal protective measures. People have found that when a fallr accidentally falls to the ground, most of them fall in a supine or prone position. At the same time, the maximum impact force that a person's abdomen (waist) can withstand is also relatively large relative to the entire body. This also becomes an important basis for the use of seat belts. Since the extent of the fall injury is related to the height of the fall, in general, all countries use a work of 2m (including 2m) or more for high-altitude operations, and stipulate the need for personal protective measures. The operation of the seat belt is also very obvious. It enables operators to work safely at high places, and in the event of an accident, it can effectively avoid the great harm caused by falling on the human body. (China Labor Insurance Network)
