A Spreadsheet for the Estimation of Chemical Exposure

This article presents a spreadsheet for the calculation of exposure estimates for pure liquid chemicals; these estimates are based on equations reported in the literature. In addition, exposure estimates for sampling, drumming and open reactor manway operations with liquid chemicals are calculated. The calculations are based on the molecular weight and vapor pressure of the subject chemical. The spreadsheet also estimates vapor pressure from the boiling point of the chemical and the estimated vapor pressure is used for the exposure calculations for chemicals without a known vapor pressure.
