Ventilation ducts are usually used in indoor ventilation systems and are usually installed in high altitude areas. If you don't pay attention, slight negligence may lead to personal safety accidents. So how to ensure the safety of personnel in the process of installation? The following small series of Shandong ventilation pipeline for you to briefly introduce.

安裝現場應劃定作業區域，并設置安全標志，禁止非作業人員進入進入。進入施工現場人員應穿戴防護用品，工作服的袖口、腰部和腿部應收緊。工作時，使用管道上方和下方的安全梯子。

The installation site shall delimit the operation area and set up safety signs to prohibit non operation personnel from entering. Personnel entering the construction site shall wear protective equipment, and the cuffs, waist and legs of work clothes shall be tightened. When working, use safety ladders above and below the pipe.

使用過程中，應隨時檢查工作平臺和腳手架。當發生變形或位移時，應采取安全措施并及時確認。一般來說，排氣扇系統和空調系統應在建筑圍護結構施工完成、障礙物清除且地面無碎片后安裝。

During use, the working platform and scaffold should be inspected at any time. In case of deformation or displacement, safety measures shall be taken and confirmed in time. In general, the exhaust fan system and air conditioning system should be installed after the building envelope construction is completed, the obstacles are removed and the ground is free of debris.

通風管道的安裝應注意電氣安全，配電箱、配電箱應防雨、防塵、防管理、防使用。接線和拆卸應由電工操作，非人員不得進行接線和其他配電操作。施工期間，應在高處搭建工作平臺或腳手架，工作平臺各節點與腳手架的連接應牢固可靠。工作平臺的寬度應滿足施工安全要求，平臺內踏板的鋪設應充分、穩定。

Attention should be paid to electrical safety in the installation of ventilation pipes. The distribution box and distribution box should be rain proof, dust-proof, management proof and use proof. Wiring and dismantling shall be operated by electricians, and non professional personnel shall not conduct wiring and other distribution operations. During the construction, the working platform or scaffold shall be built at high place, and the connection between each node of the working platform and the scaffold shall be firm and reliable. The width of the working platform shall meet the construction safety requirements, and the pedal in the platform shall be fully and stably laid.

安裝山東通風管道，建議嚴格執行各項安全技術措施，建立健全各項規章制度，并在安裝過程中嚴格監督通風管道的實施。明顯高空作業都需要我們認真對待，不僅要保證質量，安全更不忍忽視

In order to install ventilation pipes in Shandong Province, it is necessary to strictly implement various safety technical measures, establish and perfect various rules and regulations, and strictly supervise the implementation of ventilation pipes during the installation process. Any aerial work needs us to take seriously, not only to ensure the quality, safety, but also can not bear to ignore
