The latter configuration constitutes astandard pipe overpack, S100 pipe overpack, S200 pipe overpack, or S300 pipe overpack (seeSections 2.9.2, 2.9.3, 2.9.4, or 2.9.5, respectively). Empty 55-gallon drums used as dunnage tocomplete a payload must also meet the specifications presented in this section with the exceptionthat dunnage containers shall have at least one open vent port (i.e., not filtered or plugged).Table 2.9-4 identifies material content forms authorized for transport within a 55-gallon drum.Table 2.9-4 – 55-Gallon Drum: Material Content Forms Authorized forTransportForm Number123DescriptionDirect load: Solids, any particle size (e.g., finepowder or inorganic particulates)Direct load: Solids, large particle size (e.g.,sand, concrete, or debris)Direct load: Solids, large objects (e.g., metalcans containing waste)2.9-5
