Abstract:

The hazard from contact with Plexiglas, concrete, or XM40 nylon carrier material contaminated with mustard HD was investigated using the rabbit as the biological model. Contamination levels of 25, 5, and 0.5 mg of neat HD were evaluated both before and after rinsing with the solvent isopropul alcohol. Both direct contact and vapor contact were evaluated after contact time of 15 or 60 min. Contaminated surfaces were aged for 15 min or 5 hr after solvent rinse-removal. Chemical analyses were done on all test plates. Results indicate that Plexiglas does not retain significant amounts of HD after rinsing with solvent. Concrete retains significant amounts of HD even after rinsing with solvent and agine for 5 hr. The XM40 nylon carrier material retains little HD after solvent rinsing. HD-contaminated concrete is a hazard by direct vapor contact, with little difference in the effect from either contact type. Solvent soaking of HD-contaminated concrete for up to 168 hr does not totally remove the HD. HD-contaminated concrete tests indicate that HD transfer is mainly a vapor transport phenomenon since skin injury was similar from direct contact or vapor contact.
