Mr. Todd Ennis has 29 years of professional experience as a Geologist at RTI International. As such, he performs analysis of bulk insulation samples using polarized light microscopy (PLM), X-ray diffraction (XRD), and gravimetric sample reduction techniques. He also analyzes air sampling filters for the presence and concentrations of crystalline silica using National Institute for Occupational Safety and Health (NIOSH) Method 7500. Mr. Ennis has successfully maintained accreditation for the analysis of respirable silica by the American Industrial Hygiene Accreditation Laboratory Accreditation Programs, LLC (AIHA-LAP, LLC) since 2009. Mr. Ennis provides technical support for the analysis of respirable silica by XRD in conducting the Industrial Hygiene Proficiency Analytical Testing (IHPAT) Program. Mr. Ennis provides technical support for laboratory fibrous minerals audit programs, including the National Institute of Standard and Technology’s (NIST’s) National Voluntary Laboratory Accreditation Program (NVLAP) for bulk asbestos laboratories and AIHA’s Bulk Asbestos Proficiency Analytical Program. Mr. Ennis also analyzes air sampling filters for the presence of asbestos and man-made fibers by using phase contrast microscopy (PCM) by using NIOSH Method 7400 to conduct the IHPAT and Asbestos Analyst Testing (AAT) Programs. As the Program Manager for the AIHA’s Bulk Asbestos Proficiency Analytical Testing (BAPAT) Program, he is responsible for all financial management and client relation aspects for this RTI project. As Laboratory Manager for both the Optical and XRD Laboratories, Mr. Ennis is responsible for maintaining safe and efficient operations in each laboratory and for ensuring that each laboratory is staffed with properly trained technical staff. Mr. Ennis supports education and outreach efforts at RTI by providing laboratory tours for Science, Technology, Engineering and Math (STEM) when local school groups visit RTI. He provides technical support in the analysis of particulate filters by PLM and XRD and technical support in the gravimetric analysis of particulate filters (PM2.5) for several clients. Mr. Ennis has also provided laboratory assistance for the U.S. Environmental Protection Agency’s (EPA’s) Radon Measurement Proficiency (RMP) Program and administrative support to the National Environmental Laboratory Conference (NELAC).
