I’m old school and I find it difficult to read and interpret the current codes so I make my best WAG’s based on what I believe to be the intent. My basis is from the old 231 storage definitions that didn’t have the percentage of volume requirements that are so difficult to calculate.
Class 1- noncombustible so it doesn’t burn. Class 2- Class 1 in a box or crate that will burn. Class 3- combustible so it burns. You should upgrade one or two classes if there is an “appreciable” amount of Group A plastic packaging or if the storage is on plastic pallets instead of wood pallets. So your metal product is a Class 1 and you upgrade to Class 2 with the plastic tubes. To be safe, you can upgrade to Class 3 cause your system can still protect it. Class 4- Class 1, 2, or 3 with “appreciable” amount of plastics. Therefore, my WAG’s says that it’s a Class 3 commodity. Just cause I’m curious, what exactly is this metal piece that’s packed in a plastic tube?
