From suspicious packages and clandestine laboratories to transportation incidents involving commercial explosives, explosive hazards can confront responders in unexpected ways. Recognizing the warning signs and knowing when to slow down can make all the difference. In this episode of The Hazmat Files, we explore the fundamentals of explosive hazards and improvised explosive devices (IEDs) from a first responder's perspective. We'll discuss how to recognize potential threats, understand blast hazards, establish safe perimeters, coordinate with bomb technicians and law enforcement, and avoid common mistakes that can place responders at greater risk. Whether you're a firefighter, EMS provider, law enforcement officer, emergency manager, or hazmat technician, this conversation provides practical awareness, not tactical instruction, to help you recognize hazards, protect your crew, and make informed decisions during high-risk incidents. Special Guests: Adam Weiss, President & CEO, Downrange Solutions David Gazzara, Bomb Technician, Atlantic City Police Depart. Bomb Squad, US Army EOD / USAF EOD (Ret) Rick Saul, Principal Electromechanical Technologist, Sandia National Laboratories, Albuquerque Police Department Bomb Technician (Ret.)

Lithium-ion batteries power everything from smartphones and e-bikes to electric vehicles and large-scale energy storage systems, but when these batteries fail, the resulting thermal runaway events present unique challenges that extend far beyond a traditional fire for first responders. In this episode of The Hazmat Files, we examine what happens during thermal runaway, why these incidents behave differently than conventional fires, and what responders need to know about fire behavior, toxic emissions, explosion hazards, battery reignition, air monitoring, scene management, and responder safety. Join us as we explore current research being conducted by UL's Fire Safety Research Institute and Chemical Insights Research Institute, lessons learned from real-world incidents, and practical considerations for firefighters, hazmat teams, EMS, and emergency managers responding to one of today's fastest-growing hazards.

During a hazardous materials incident, air monitoring is a critical tool for protecting responders, the public, and the environment. But collecting readings is only the first step, the real challenge is understanding what those readings mean and using them to make informed decisions in rapidly changing conditions. In this episode of The Hazmat Files, industry experts discuss how the Emergency Response Planning Guidelines (ERPGs) help turn air monitoring data into actionable information. Learn how ERPG values support protective action decisions such as evacuation and shelter-in-place, and how air monitoring guides response efforts from initial assessment through recovery.
