International Training Conference & Expo


Improving Fire Investigator Health and Safety – Part 2

Wednesday, April 13, 2022 (10:30am – 12:30pm) (Ballroom 5)


This session will continue our look research projects underway and recently completed that directly impact understanding fire investigator health and safety. Presentations will address the UL Fire Safety Research Institute's post-fire gas and particulate study, an update from National Institute for Occupational Safety and Health (NIOSH) staff on the Fire Fighter Cancer Cohort Study, focusing on the Fire Investigator Expansion Study and the National Firefighter Registry with a focus on how it relates to fire investigators.

Learning Objectives:

  • Better understand the various particulate and gas hazards present in the post-fire environment

  • Know how the forthcoming federal firefighter registry applies to fire investigators

  • Understand how NIOSH and others are working to increase the understanding of the post-fire environment

Dan is director of research with UL FSRI.  Throughout his career, he has conducted fire investigation related studies in a wide range of areas including firefighter line of duty deaths, the post-earthquake fires in Kobe, Japan, oil field fires in Kuwait, the Station Night Club fire, and the Cook County Administration Building fire in Chicago.  He has a PhD in Fire Engineering from the University of Canterbury.  Dan is a member of the NFPA, the IAAI and a Fellow of the SFPE.  He has assisted with the review and development of several NFA and CFITrainer.net courses involving fire dynamics.


Dr. Gavin Horn

Gavin Horn is a Research Engineer with the UL Fire Safety Research Institute (FSRI). Gavin's research interests include firefighter and fire investigator health and safety, first responder technology development, material testing, and nondestructive evaluation. Before joining the UL FSRI team, he served as the Director of IFSI Research Programs at the University of Illinois Fire Service Institute (IFSI) for 15 years and as a firefighter, apparatus engineer, and fire investigator with the Savoy Fire Department (IL). Gavin holds a Ph.D. in Mechanical Engineering from the University of Illinois at Urbana-Champaign and a ME in Fire Protection Engineering from the University of Maryland. He has published over 80 peer-reviewed journal manuscripts and given presentations at meetings, conferences, and symposia around the world.


Alex Meyer

Alex Mayer is a health scientist working at the National Institute for Occupational Safety and Health (NIOSH). He is currently working on the National Firefighter Registry (NFR) team with the primary goal of understanding the link between cancer and the US fire service. He graduated with a Master of Public Health in Epidemiology from the University of Cincinnati in 2016. Since joining NIOSH in 2017, Alex has focused primarily on research relating to exposure to flame retardants and firefighter health. He has published over ten journal articles and technical reports on research relating to firefighter safety and health.


Dr. Miriam Calkins

Dr. Miriam Calkins is an Associate Service Fellow and Research Industrial Hygienist with the National Institute for Occupational Safety and Health. She is the Exposure Assessment Core director in the Fire Fighter Cancer Cohort Study and the Project Officer for a feasibility study of PFAS exposure and health indicators in occupational settings. She completed her doctorate in Occupational and Environmental Hygiene and her master's in Exposure Science at the University of Washington in Seattle. Currently, Dr. Calkins' research focuses on per- and polyfluoroalkyl substances (PFAS), comprehensive exposure assessments for firefighters during fire response, training and investigations, and occupational heat exposure. Additional research interests include heat stress and traumatic injury in construction and agricultural occupations and optimization of monitoring strategies for application to research and practice. Dr. Calkins is an IAAI Health & Safety Committee advisory panel member.
