Use of subsurface foam injection on covered IFR tank

  1. Sep 23, 2016 #1
    According to NFPA 11, subsurface foam injection can't be used on IFR tanks with fixed/covered roof. However, this has been done for a long time by various companies and there doesn't seem to be any issues with that. Can anyone give their opinion based on knowledge/experience why this should not be done? Thanks.

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.

    This is foam injection as part of the actual firefighting?
