Article 2.0.7 of Technical Code for Safety of Working at Height in Building Construction (JGJ80-9 1) states that reliable anti-skid, cold-proof and anti-freezing measures must be taken when working at height in rainy and snowy days. All water, ice, frost and snow should be removed in time. Lightning protection facilities should be set up in advance for high-rise building operations. In case of bad weather such as strong winds and dense fog below level 6, it is not allowed to climb high in the open air or hang aloft. After snowstorm and typhoon rainstorm, the safety facilities for working at heights should be checked one by one. If it is found to be loose, deformed, damaged or falling off, it should be repaired immediately. Technical Specification for Safety in Use of Construction Machinery (JGGGJ33-20014.10.7) When there is strong wind above level 6 or bad weather such as rainstorm, heavy snow and fog in the open air, the lifting operation should be stopped. After the rain and snow, before the operation, try hoisting first, and then make sure that the brakes are sensitive and reliable before the operation.
