A new test procedure was outlined for identifying drum materials at remedial action hazardous waste sites using Fourier transform infrared spectroscopy (FTIR). Drums of chemicals were sampled using this technique and one tank was sampled for the FTIR attenuated total reflectance (ATR) analysis. The procedure involved placing a drop or portion of material on a germanium crystal ATR cell obtaining spectra. The data obtained were compared to those achieved using a gas chromatograph/mass spectrometry analysis and to results of compatibility testing. The system was able to obtain spectra from all viscous and gelatinous samples. The FTIR procedure identified many, but not all, significant components of actual samples obtained from a site. The data obtained from FTIR analysis compared to compatibility testing is considered useful in developing personal protection strategies based on sound industrial hygiene principles. A disadvantage is the exclusion from analysis of aqueous samples. Further work is suggested for investigating the use of alternate ATR crystals or liquid cells to improve the detectability of chlorinated species in mixtures. The use of improved spectral search procedures must be examined, as the FTIR instrument used is not able to perform spectral searches, especially on mixtures.
