Jan 22, 2019 · containers." Are GIS considered to be gas containers? No. The definition of "Gas container" was not intended to include GIS, as the regulation treats GIS and gas containers in separate fashions. For example, GIS are not weighed, but gas containers are weighed annually to determine if there are SF 6 losses from one year to the next. 6.
