Description:
The paper gives results of tests that were performed in a controlled-environment test room to measure particle concentrations and size distributions and concentrations of selected volatily organic compounds during, and following, application of water-based cleaners to realistic surfaces. Tests were performed in a closed room supplied with high-efficiency particulate air (HEPA)-filtered air and operated at different air exchange rates. Particle concentrations and size distributions were measurede with an aerodynamic particle sizer (APS). 2-Butoxyethanol (2-BE) was collected on Tenax and analyzed by gas chromatography. Air exchange rates were measured throughout each test. Results of the particle concentration and size distribution measurements are presented and discussed as they relate to the concentration of the cleaner and the room air exchange rate. Results from the tests are used to estimate the depletion rate of the droplets during the tests.
