According to the requirements of gb23468-2009 national standard, when the operation height is 2m or more from the falling height datum plane, the safety belt fall arrester should be used. Before using the safety belt fall arrester, we should check whether all parts are in good condition, whether the safety rope and tie are torn, disconnected and moldy, whether the metal accessories are cracked and corroded, etc. if there are any problems affecting the function of the fall arrester, we should replace it immediately before working at height. When working at height, hang the safety belt fall arrester in a fixed position, and it is forbidden to hang it in a moving or unstable position.
The impact of the material of the components of the fall arrester. Due to the increasingly fierce market competition, some enterprises often lower the price in order to seize the market, and the purpose of enterprises is to make profits. Therefore, they will "cut corners on work and materials" in material selection. As a result, the quality of fall arresters is difficult to be guaranteed, and the lives of high-altitude workers are also threatened.
Impact on the qualification of production enterprises. The production technology of the old fall arrestor, that is, the common steel wire rope fall arrestor, is relatively mature. Many enterprises without business license, production license and other unqualified production qualifications begin to process and sell. The after-sales guarantee of the fall arrestor produced by these enterprises is poor, and the product quality is difficult to be guaranteed, but the price is relatively low.
The choice of spraying paint on the surface of the fall arrester. The green hammer paint of commonly used fall arresters is almost pollution-free water-based paint. As painting workers and socially responsible enterprises, more and more choose water-based paint, but the price of water-based paint is much more expensive than ordinary paint, so it also increases the cost of fall arresters.
