4,4(prime)-Methylene Dianiline (MDA) and thermal abuse of Rigid Polyurethane Foam

摘要

Rigid Polyurethane Foam is used for weapon support in conjunction with the H1501A Transportation Accident Resistant Container (TARC). The foam is flame resistant, however like all organic materials, it will burn with enough heat and oxygen. Normally the foam will not melt, but will form a char and is nonhazardous. There are instances when the combination of heat and oxygen will cause the foam to decompose resulting in 4,4(prime)-Methylene Dianiline (MDA) a Liver toxin and suspect carcinogen. MDA contamination occurred during robustness tests DROP-20/BURN-20. This report chronicles the events causing the contamination and method used for disposal.
