Industrial Hygiene Expert Stephen Petty’s Testimony

Industrial hygiene expert Stephen Petty’s testimony to the New Hampshire Senate in January 2022.  He explains why facial coverings, including N95s are ineffective for controlling viral respiratory illnesses. He references many studies in his presentation which are included in the accompanying PDF. The document presented to the Senate committee has multiple slides per sheet, so the pages he mentioned during his testimony are different than in the PDF file, which has single slide per page.
