How many winds prohibit open-air aerial work?

The national standard GB/T3608-2008 "Classification of Work at Height" stipulates that work at height is not allowed when the gust is above level 5 (wind speed is 8.0m/s). Working at heights more than 2m (including 2m) from the reference plane of falling height is called working at heights.

Expand:

First, the wind speed level

For aerial work, wind speed is the most basic reference parameter. When the wind speed reaches 6 and 7-8, it is called gale and gale respectively, which is easy to cause risks and harm. Therefore, when the wind reaches level 6 and level 7-8 and above, it is necessary to stop aerial work immediately.

Second, the wind direction.

Wind direction is another very important parameter. For aerial work, due to the limited space, it is sometimes necessary to use rod or cloth tools, which need stability to ensure safety. Therefore, in the case of strong wind direction and easy fluctuation of wind force, it is necessary to consider delaying aerial work.

Third, rain and snow weather.

When the weather turns to rain and snow, rain and snow may cause the high-altitude site to be slippery and affect the stability of scaffolding. When working high above the ground, always pay attention to the weather forecast and stop working high above the ground in dangerous rain and snow as soon as possible.

In short, different wind speed levels and directions should be considered in different aerial working environments. It is suggested that the construction party immediately suspend the relevant aerial work when the meteorological department issues a strong wind warning. In addition, when working high above the ground, always pay attention to the weather forecast to avoid the danger caused by excessive wind speed.
