If this was my call, I would not require seals for conduits coming up out of the floor to be changed. Natural gas has a vapor density of about 0.75 and in the event of a leak will go up. Just pour the 6" seals. In my opinion they really serve no function in this case, except to satisfy a code requirement.

don,
thanks for the reply...we supply the equipment i.e. gas turbine, generator and all the goodies that go with it, there are 8 here on this site...the customer hired a contractor to figure out how to connect everything...we provided them with the drawings....they put the seals there...
i dont even think we called for them...
if they are installed do they even have to be poured? i think that if they are going to require them there then they should be the oversized seals...or they should be removed all together...the pull box and the peckerhead are not explosion proof probably not even nema 3r
