- Abstract
- Oil based aerosol "Smoke" commonly used for testing the efficiency and penetration of High Efficiency Particulate Air filters (HEPA) and HEPA systems can produce flammability hazards that may not have been previously considered. A combustion incident involving an aerosol generator has caused an investigation into the hazards of the aerosol used to test HEPA systems at Hanford. While conducting an "In-Place" aerosol test, the Ventilation and Balance group experienced a combustion incident using the ATI TDA 5A aerosol generator. The incident was described as a "Pop" with a large puff of smoke and a flash coming from the end of the flex hose used to transmit the aerosol to the filter housing being tested. As a result of this incident the Ventilation and Balance group started testing the aerosol production, operating configuration and flammability of aerosol materials in the ATI TDA 5A aerosol generator. The purpose of this paper is to discuss the results of this testing and make recommendations for the use of the ATI TDA 5A generator.
