Title: New performance data for {open_quotes}Emery 3002{close_quotes} and {open_quotes}Emery 3004,{close_quotes} two Army-approved safe materials to replace DOP in mask and filter testing

Abstract

At the 22nd Conference in Denver, we reported that the U.S. Army Surgeon General (SGJ) had approved our developmental material {open_quotes}Emery 3004{close_quotes} as a safe replacement for the suspected carcinogen DOP (dioctyl phthalate) in mask and filter testing throughout the Army. Subsequently the SG approved a second, less viscous material, {open_quotes}Emery 3002,{close_quotes} for similar applications. We have measured the viscosities and surface tensions of these liquids over a wide range of temperatures, and have initiated liquid breakup studies through Laskin and two-fluid nozzles. New measurements have been carried out with both liquids, e.g. using the ATI, Inc., TDA-4A cold generator to disperse aerosols for which droplet size distributions were measured using the TSI, Inc., Differential Mobility Particle Sizer (DMPS). Among the findings were that Emery 3004 performs much like DOP in the TDA-4A, with some possible advantages, while Emery 3002 in the TDA-4A produces mean droplet diameters about one-half those of Emery 3004 or DOP. This suggests that Emery 3002 could yield more rigorous filter tests with a smaller consumption of material. New laboratory results will be summarized. Sources of the {open_quotes}Emery{close_quotes} materials will be discussed since the production facility formerly operated by Emery is now run by the Ethylmore » Corporation and the source products are now known as {open_quotes}Ethylflo 192{close_quotes} (Emery 3002) and{open_quotes}Ethylflo 194{close_quotes} (Emery 3004).« less

  • The particle size distribution, concentration, liquid to aerosol conversion rate and ignition properties of DOP, Emery 3004 and Emery 3006 aerosols generated by the NUCON Aerosol Generators Models SN-10 and DG-F were obtained. Results demonstrate the Emery products are acceptable replacements for DOP in performing leak testing of HEPA filters.
  • HEPA filters are used in nuclear facilities for contamination control and air treatment and are constructed to be 99.97% efficient in trapping particles of 0.3 microns or larger in size. Prior to installation at Hanford facilities HEPA filters are tested against the manufacturer`s efficiency specifications by the Hanford Environmental Health Foundation using an aerosol with a monodispersed particle size of 0.3 microns. The oil or material used for generating the aerosol, has historically been Dioctl Phthalate (DOP). But, in 1980 DOP was classified as a suspected carcinogen, and the search for substitute materials was under way. Corn oil produced goodmore » quantities of the correct sized particles but it tended to clog the generating equipment; Polyethylene Glycol 400 (PEG) and Dioctl Sebacate (DOS) were also tried but failed for various reasons. Emery 304 was tested and produced a good quantity of correctly sized aerosol and did not clog or damage the equipment in any way. Upon further testing, in September 1992, the DOE Richland Operations authorized the use of Emery 304 for in situ HEPA filter testing on the Hanford site.« less
  • The goal of the Army hazardous waste minimization program is to achieve a 50 percent reduction of the hazardous waste generated by calendar year 1992 (CY92), as compared to baseline CY85. A first step in achieving effective hazardous waste management is to conduct a thorough hazardous material inventory. Volume I describes a method created to inventory hazardous material by collecting supply data from Logistics Control Activity (LCA) at the Presidio, San Francisco, CA, an comparing this data with the Material Safety Data Sheet (MSDS) in the Hazardous Material Information System (HMIS). Volume H lists hazardous material data collected for themore » Eighth U.S. Army (EUSA), Korea. Common elements between the two data bases were compiled, analyzed, and validated. It was found that the intersection of the two data bases created a composite list that substantially reduced the number of nonhazardous wastes included in the individual lists. This method may also be applied to supply data from other Army installations.« less
