  2. Sulfur hexafluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride

    Sulfur hexafluoride was used as a non-toxic test gas in an experiment at St John's Wood tube station in London, United Kingdom on 25 March 2007. [29] The gas was released throughout the station, and monitored as it drifted around.

    en.wikipedia.org/wiki/Sulfur_hexafluoride...

    After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. [1] SF 6 gas is electronegative and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow of sulfur hexafluoride gas, and an arc is struck between ...

    From the cases analyzed, it was determined that the over pressure of inert gas systems can constitute a risk even in the presence of a system designed and built according to technical standards. [5] On September 20, 2018, two people died after an inert gas leak from a fire suppression system located in the State Archives in Arezzo (Italy). [ 6 ]

    en.wikipedia.org/wiki/Fluorinated_gases

    The F-gas Regulation adopts an approach based on containment and recovery of F-gases as well as imposing obligations on reporting, training and labeling on those using F-gases. On 26 September 2011, the Commission issued a report on the application, effects and adequacy of the Regulation, drawing from the results of an analytical study it ...

  9. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
