You must placard a shipment containing class 4.1 Flammable Solid when _________.

All products that meet the definition of hazardous materials must be placarded at some point. There are two placard tables. Table 1 materials must be placarded when any amount is transported. Except for bulk packaging, the hazard classes in Table 2 are required to be placarded only if the total amount transported is 1,001 pounds or more, including the package. Add the amounts from all shipping papers for all Table 2 products on board.
You may use DANGEROUS placards instead of separate placards for each Table 2 hazard class when:
You have 1,001 pounds or more of two or more Table 2 hazard classes, requiring different placards, and You have not loaded 2,205 pounds or more of any Table 2 hazard class material at any one place. (You must use the specific placard for this material.)
