METHOD OF CHANGING CONCENTRATION OF EXPLOSIVE GAS MEDIUM TO A SAFE CONTAINER INSIDE Russian patent published in 2019 - IPC G01N33/22 B65B69/00 

FIELD: technological processes.

SUBSTANCE: invention relates to investigation of materials, namely to methods for decontamination of explosive gas medium inside transport container, and can be used at works on opening of containers with unknown gas medium, which are in operation for a long period of time. Method includes creation of inert atmosphere in container using inert gas and container maintenance till safe concentration of gas medium is established. Container is exposed by force to striker installed in guide located along contour of container inspection window. Into formed hole through hole in striker inert gas is supplied to achieve safe concentration of explosive gas mixture. At the same time guide and striker are made of material excluding spark at their interaction with container.

EFFECT: achieving safety by preventing the risk of fire or explosion when opening the container; enabling remote control of the process of releasing an explosive gas mixture from a container and filling it with an inert gas to the required volume and achieving safe concentration of the gaseous medium.
