three experiments were performed to measure the ARF during the burning of contaminated

PS. Only liquid UNH was used as a contaminant. The results are listed in Tables A.50 and

A.52 in Appendix A and relevant data summarized in Table 5-5.

The highest measured ARF is 7.8E-3, with an RF of 0.9. There is no meaningful median

value for such a restricted data set.

Experimental data on the behavior of combustible solids, such as trash, during explosive

events have not been uncovered. Based upon some general observations, the behavior of the

substrate can be estimated and the associated behavior of the surface contamination inferred.
