Abstract: In high-altitude operation of petrochemical industry, five-point double-hook safety belt is often used to prevent operators from falling from high places. However, during the operation of refining plant construction, unexpected fire, gas leakage, collapse and other emergencies may occur. Due to the use of safety belts, risks of personal injury and death may occur to operators working for high-altitude operation. By making minor structural improvements to the existing high-altitude operation safety belts, and setting a quick decoupling device, the safety belts can be decoupled safely and quickly by operators working for high-altitude operation in sudden emergency and dangerous situations so that the purpose of safe escape can be achieved.

Key words: quick decoupling, high-altitude operation, safety belt, design
