THMG507 – DOT Class 2 | Part II

August 01, 2025

We jumped back in with DOT Class 2 hazmat and covered a ton of ground—so much, in fact, that we couldn’t fit it all into one episode. We also explore when non-flammable is flammable.

Thank you to our sponsor for this episode:

ObexionFR

ObexionFR is a mobile solution for first responders dealing with lithium battery fires, created by former FDNY Hazmat experts. It uses advanced science to neutralize fires by addressing heat, oxygen, and fuel, quickly containing and extinguishing them while keeping toxic gas levels safe. The process cools the battery, isolates oxygen, and prevents further ignition, providing a reliable tool for challenging battery fire incidents. Check it out.
