Philip Smith, PhD, CIH Moderator
U.S. Department of Labor - OSHA
Sandy, UT 
United States of America
Phil has received degrees from Brigham Young University (BS), the University of California, Berkeley (MPH), and Utah State University (PhD, toxicology). He served over 23 years in the U.S. Navy Medical Service Corps as an industrial hygiene officer, and over 5 years as a member of the OSHA Health Response Team. He now supports nationwide OSHA field activities as the Director of the Industrial Hygiene Chemistry Division located at the OSHA Salt Lake Technical Center. Phil has published over 50 book chapters and peer-reviewed publications and is the lead editor of the 2013 American Industrial Hygiene Association publication "Important Instrumentation and Methods for the Detection of Chemicals in the Field." Phil became board certified by the ABIH (comprehensive practice) in 1993.

Evaluation of a Portable GC/PI Detector

11:35 AM - 11:55 AM  Total Time: 20 
Most portable direct-reading instruments are not capable of specifying individual chemical compounds or extremely bulky. Recently, a portable gas chromatograph/photoionization detector has been commercialized. This instrument is designed to measure individual VOC compounds, measure a worker's breathing zone exposure, and be portable. However, this instrument has not been fully evaluated via laboratory performance tests.
