The variables studies in the experimental work leading eo the development of this model include temperature, time, ventilation rate, KVCM content of the resin, mesa/volume ratio and resin type (varying in porosity). The results obtained from a statistically designed series of 24 exper iments show the interactions of all the variables and permit (1) the effects of the variables to be established and (2) the derivation of a model which permits the AVCM levels to be predicted for any combination of the variables. The developed model has been used to predict the AVCM level in BFG warehouses at Avon Lake, Louisville and Pedricktown. We have found exeallant agreement between predicted and measured AVCM levels at these three locations* * and under a variety of storage conditions. Additionally, the model has been used to show chat wades- less-than the most severe storage conditions, the OSHA action level will aoc be exceeded (500 ppb AVCM) when the BVCM concent of the scored resin does not exceed IS ppm. Even-under, the most extreme storage conditions the OSHA action level Is not exceeded -when--the HVCM content .o^th^~reb:idaT9ss:9^9Mppm or -less.
