Guidelines for transloading polymeric methylene diphenyl diisocyanates (PMDI) from railcars to tank trailers are posted on the Web site of the Center for the Polyurethanes Industry of the American Chemistry Council (ACC) at polyurethane.org
The guidelines were developed to describe various options for transloading PMDI and are not meant to be all-inclusive and may not cover all legal requirements for transloading at a particular facility or operation. Additionally, material safety data sheets (MSDSs) should be reviewed and considered prior to transloading PMDI, the information points out.
