(b) LNG being transferred into stationary storage containers shall be compatible in composition or temperature and density with the LNG already in the container. When making transfers into fueling facility containers, the LNG shall be transferred at a pressure that will not exceed the set pressure of the pressure relief device. (c) When the composition or temperature and density are not compatible, measures shall be taken to prevent an excessive rate of vapor evolution. (d) At least one licensed or certified individual shall be in attendance while unloading is in progress. (e) Ignition sources shall not be permitted within 25 feet of the transfer area or within the distances specified as classified areas in Table 1 of §14.2513 of this title (relating to Electrical Equipment) while transfer of LNG is in progress.
