Keith Langworthy

Keith Started his career with MIOSHA's Asbestos Program May 1, 2000. Prior stints as a Dow Chemical Intern and Industrial Hygiene Technician at DeLisle Associates in Kalamazoo offered Keith a good look at IH work in large industrial facilities in Michigan. Since 2008, he's been a MIOSHA Senior Industrial Hygienist. While in the Asbestos Program, he conducted enforcement inspections throughout the state for the first 10 years of his career. In 2011, Keith took on expanded responsibilities with a transfer to MIOSHA's Construction Safety and Health Division and continued conducting enforcement inspections of all health hazards in a position covering the West side of the State. Keith's most memorable worksites include the World Trade Center Clean-up operation in Jan-Feb 2002, working alongside OSHA Industrial Hygienists as a part of the Hurricane Katrina response efforts in November 2005, and covering SW Michigan's employees responding to the Enbridge Oil Spill cleanup in 2010. Keith is currently the Co-Chair of MIOSHA's Disaster Response Team(DRT). He encountered his most unusual worksite while initiating a MIOSHA inspection during a brief interruption in a deposition.

In October 2022, Keith came to MIOSHA CET's Training & Consulting Section as a Senior Industrial Hygienist covering the Western and Southwestern counties of the state.
