Not counted. It can be cut using cutting blades.
I’m not sure what the original question was; in my opinion, it doesn’t involve working on the equipment itself； However, according to the hierarchical management of hot work, it should be consistent with the hot work performed on the equipment itself.
I mean, is it necessary to conduct a safety gas analysis of the equipment? Are there any relevant specifications?
If it is not possible to disconnect the device, it is necessary to clean the device and check for combustible gases
When performing hot work at entrances and exits, gas analysis must definitely be carried out.
