  • .1 foam shall not be installed in void spaces that contain ignition sources;

  • .2 foam shall not be installed adjacent to fuel tanks, unless the boundary between the tank and the space has double continuous fillet welds;

  • .3 the structure enclosing foam shall be strong enough to accommodate the buoyancy of the foam;

  • .4 piping and cables shall not pass through foamed spaces unless they are within piping and cableways accessible from both ends;
