Yunku Industrial Safety

Confined space refers to a closed or partially closed space with narrow inlet and outlet. With poor natural ventilation, these places are not designed as a fixed work place, and easy to cause toxic and harmful, flammable and explosive substances accumulation or insufficient oxygen content. Confined space operation refers to the operation activities carried out by operators in a confined space.

First, disregard safety procedures

In order to catch up with the construction period or save effort, some enterprises do not pay attention to safety management, ignore the safety operation procedures. In the process of confined space operation, if the safety operation procedures are not strictly followed, it will lead to some accidents. Therefore, before confined space operations, safety training and operation procedures must be developed to ensure that everyone is familiar with safety knowledge and operation specifications. At the same time, it is necessary to strengthen the supervision and guidance of the operation process, correct violations timely, and ensure the safety of operations.

Second, blind rescue, lack of rescue measures

In the course of confined space operations, if an accident occurs, immediate rescue measures need to be taken. There are blind rescue situations in some enterprises, such as directly entering in the confined space without effective protective measures, resulting in rescuers poisoning, choking. Therefore, in the confined space rescue, we must take effective protective measures and rescue means, such as taking professional rescue equipment and rescuers At the same time, it is necessary to follow the principle of "saving people first, then saving things" to ensure the safety of trapped people's lives.

Third, lack of ventilation measures

Poor ventilation is a common problem when working in confined space. Some enterprises in order to save trouble or money, did not take effective ventilation measures, resulting in high or low gas concentration in the operating environment, resulting in poisoning, hypoxia and other accidents. Therefore, when working in confined space, effective ventilation measures must be taken, such as opening the fan, doors and windows, etc., to ensure that the gas concentration in the working environment meets the safety standard.

Fourth, no gas detection

Gas detection is an essential step before working in confined spaces. Some enterprises in order to save trouble or time, operate without gas detection, resulting in operators poisoning, suffocation and other accidents. Therefore, before the confined space operation, the gas in the working environment must be detected to ensure that the concentration of oxygen, combustible gas, and toxic gas meets the safety standard. At the same time, protective equipment such as gas detectors and breathing apparatus should be equipped to ensure the safety of operators.

Fifth, the use of non-standard equipment

In order to save costs, some enterprises use non-standard equipment or equipment with poor quality in confined space operations. There are many defects and safety hazards in these devices, such as no protective cover, faulty switches, broken cables, etc. These defects can lead to equipment failures or accidents during operation, which can endanger the lives of operators. Therefore, when choosing confined space operation equipment, it is necessary to choose equipment that meets national standards and industry standards, and regularly check and maintain.
