目的摸索大型作业场所多人同时进行热烟雾作业的安全操作方法。方法现场试验。采用不同区域独自同时施工方法、同一区域轮替施工方法和小组编队,统一指令操作施工方法。结果不同区域独自同时施工方法,因无法保证操作人员安全而中止;同一区域轮替施工方法,施放的烟雾不能满足作业的质量要求;小组编队统一指令操作法,施放的烟雾符合规定的要求,操作人员能同时安全撤离作业面。结论每个工作人员操作的同步性是多人能够同时进行热烟雾作业的关键点,准确地控制各工作环节及流程,是操作人员安全撤离工作面的重要保证。
Objective To explore the safe operation of multi-person in large workplace at the same time thermal smoke operation. Method Field test. Using different areas at the same time construction methods, the same area rotation construction methods and group formation, unified instruction operation construction method. As a result, the methods of simultaneous construction in different regions alone could not be stopped due to the inability to ensure the safety of the operators. The method of alternation and construction in the same area could not meet the quality requirements of the operation. The unified command operation method of the formation group complied with the prescribed requirements and operation Personnel can safely leave the work surface at the same time. Conclusions The synchronicity of each staff member is the key point that many people can carry out the thermal smog operation at the same time. It is an important guarantee for the operator to safely withdraw from the work surface by accurately controlling various work processes and processes.
