Go HERE for a copy of RIPA’s comments in response to proposed prohibitions on co-loading onto trailers and railcars different hazmats which could react dangerously if allowed to mix. RIPA points out the impractical burden this could create for all shippers and carriers, as well as the low quantities associated with reconditioning and container residues. RIPA also advises that there already exist certain  rules on segregation of hazmats which could provide a better forum or context for any rule changes.
