When the wind is greater than several levels, it is forbidden to suspend operations.

When the wind force is greater than 4, it is forbidden to suspend operations.

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.

Common objective factors that directly lead to falling during aerial work are as follows:

1, and the gust wind force is above level 5 (wind speed is 8.0m/s);

2, GB/T4200-2008 provisions of grade II or above high temperature operation;

3. Working environment with average temperature ≤5℃;

4. The contact cold water temperature is less than or equal to12℃;

5. There are slippery properties such as ice, snow, frost, water and oil in the workplace;

6. The light in the workplace is insufficient, and the visibility is almost poor.

Legal basis:

Article 55 of the Law of People's Republic of China (PRC) on Work Safety.

Employees have the right to stop working or leave the workplace after taking possible emergency measures when they find an emergency that directly endangers their personal safety.

The production and business operation entity shall not reduce the wages, welfare and other benefits of employees or terminate the labor contract with them because they stop working or take emergency evacuation measures in the emergency mentioned in the preceding paragraph.

Article 41 of the Law of People's Republic of China (PRC) on Work Safety.

Production and business units shall establish a safety risk classification control system and take corresponding control measures according to the safety risk classification.

Production and business units shall establish and implement the system of investigation and management of hidden dangers of production safety accidents, and take technical and management measures to find and eliminate hidden dangers of accidents in time. The investigation and management of hidden dangers of accidents shall be truthfully recorded, and the employees shall be informed by means of workers' congress or workers' congress and information bulletin board. Among them, the investigation and management of major accidents should be reported to the departments responsible for the supervision and administration of production safety and the workers' congress or the workers' congress in a timely manner.

The departments of the local people's governments at or above the county level responsible for the supervision and administration of production safety shall incorporate the hidden dangers of major accidents into the relevant information systems, establish and improve the management and supervision system of hidden dangers of major accidents, and urge the production and business operation entities to eliminate hidden dangers of major accidents.

Article 56 of the Labor Law of People's Republic of China (PRC)

Laborers must strictly abide by the safety operation rules in the process of labor.

Workers have the right to refuse the illegal command and forced risky operation of the management personnel of the employer; Have the right to criticize, report and accuse acts that endanger life safety and health.
