Several strong winds stopped working at high altitude.

During the construction, the operation is stopped due to the strong wind of level 6, and the operation is stopped due to the strong wind of level 6 such as hoisting.

Do not engage in aerial work in the open air in six-level gale or heavy rain, heavy snow and foggy weather. In addition, you must do a good job in safety inspection during aerial work. If abnormal behaviors of people and things are found, they should be eliminated in time to meet safety requirements, so as to control falling accidents.

When there is no reliable protective facilities, you must wear a seat belt when working at height, otherwise you are not allowed to work at height. At the same time, the quality of seat belts must meet the safety requirements of use, so that they can be hung high and used low. Be sure to check whether the pedal is safe and reliable before climbing the mountain, such as whether the pedal has load-bearing capacity; Whether the root of the wooden pole is rotten. It is forbidden to walk on asbestos shingles, particleboard and plywood ceilings.

The national standard GB/T3608-2008 "Classification of Work at Height" stipulates: "Any work that may fall from a height of more than 2m (including 2m) from the reference plane of falling height is called work at height." According to this regulation, the scope of aerial work in the construction industry is quite extensive. When working in a building, if you work on a shelf higher than 2M, it's aerial work.

In order to prevent people and things from falling from heights in the process of operation, according to the characteristics of the construction industry, various operations, hanging and climbing operations, working platforms and interchange operations with opening and limb nature are carried out within the structural scope of buildings and structures in the construction and installation projects.

As well as all kinds of holes, pits, ditches, grooves and other construction operations on the site outside the main structure and beside the passage, as long as they meet the above conditions, they are all treated as aerial work and protected.

Wind power refers to the strength of the wind blowing on an object. Generally speaking, according to various phenomena caused by wind blowing on objects on the ground or water surface, the magnitude of wind power is divided into 18, with the smallest being 0 and the largest being 17.

Wind speed is the forward speed of the wind. The greater the air pressure difference between two adjacent places, the faster the air flow, the greater the wind speed and the greater the wind force. Therefore, the magnitude of wind is usually expressed by wind power. The unit of wind speed is meters per second or kilometers per hour. When the weather forecast is released, the wind level is mostly used.

Aerial work refers to the work carried out by people at a height based on a certain position. The national standard GB/T 3608-2008 "Classification of Work at Heights" stipulates: "Any work at heights more than 2m (including 2m) from the reference plane of falling height that may fall is called work at heights." According to this regulation, the scope of aerial work in the construction industry is quite extensive. When working in a building, if working on a shelf more than 2m, it belongs to aerial work.
