Confined space operation refers to the personnel to enter the limited space to implement the operation. Common confined space operations include removal and cleaning operations, equipment installation, replacement and repair operations, painting, anticorrosion, waterproofing and welding operations, inspections and overhaul operations. For example, entering the sewage well for dredging operations, entering the fermenter for cleaning operations, entering the sewage regulator to replace equipment, anticorrosive operations in the tanks, entering the inspection wells, heat pipe trenches for inspection operations, etc., all belong to the confined space operations.

Correctly identifying the limited space is the first step in preventing accidents. It is also the first step to ensure the safety of personnel. The following are some common identification methods:

1. Observe the dimensions of the space

The dimensions of a confined space are usually relatively small and cannot accommodate too many people and equipment. Therefore, by observing the dimensions of the space, you can initially determine whether it is a confined space.

2. Checking entrances and exits

Entrances and exits to a confined space are usually narrow and may contain obstacles or restrictions. Therefore, checking for unobstructed entrances and exits is an important step in identifying a confined space.

3. Evaluate ventilation

Confined spaces are usually poorly ventilated and prone to the accumulation of harmful gases. Therefore, by observing or measuring the air quality and gas concentration in a space, you can determine whether it is a confined space.

4. Understanding space use

Different confined spaces have different uses and characteristics. Understanding the uses and characteristics of spaces helps to recognize the confined spaces more accurately and to take appropriate safety measures.

The hazards of confined space operation accidents should not be ignored, in order to effectively avoid the occurrence of such accidents, effective avoidance of confined space operation accidents need to start from many aspects, strengthen the implementation of measures such as safety management, training, facility construction, on-site management, planning of operation processes and emergency preparedness. Only in this way can we minimize the occurrence of accidents in confined space operations.
