INHIBITION OF FLASHING OF AEROSOLS

Abstract

Quantitative and qualitative tests were performed with dibutyl phthalate (DBP) and bis (2-ethylhexyl) hydrogen phosphite (B2EHHP) aerosols. Both aerosols were found to be quite flammable, and the B2EHHP aerosol flame front, on one occasion, propagated several times faster than the DBP during its tests. DBP lean limits of 27.8 to 17.3 mg/l for 74 to 130 micron-meanweight- diameter aerosols indicate that the lean limit decreases as the drop size increases in this size range. Ignition studies indicated that it was not possible to ignite flammable concentrations of DBP aerosols with spark discharge or exploded wire ignition systems. Hot wire, 110v shorted nichrome wire, and gas flame ignition systems resulted in identical lean limits in DBP, although the gas flame ignition system is the most positive ignition source.
