I agree that these are Group A plastic at the very least; and that the totes are caged for rigidity, which as others have said makes it a stable pile, preventing water from getting directly on the bottom tote. I have asked the customer to give us a list of materials that are stored in the totes. Thanks for the info, as I had not known about section 3404 in IFC, stating they may be considered full totes if flammable or combustible materials were stored in and there is any in them. This is another one of the reasons to be a member of AFSA and pay for this forum. Lots and lots of good help. Thanks for the heads up!
