About this episode

In this episode, Bob teams up with Jake to answer four quick questions from the mailbag about hazmat response and chemistry.

In this episode, Mike’s off on assignment, so Bob gets to team up with Jake again—and we’re kind of hoping this turns into a regular thing. It’s four quick questions pulled from the old mailbag, and it always gets things moving. Give it a listen. 1. How important is actual chemistry in hazmat response? 2. What the hell does octane mean on the gas pump? 3. What tools are non-negotiable when dealing with unknowns? 4. Can something melt below its freezing point? Also, quick heads-up: the show’s format is shifting a bit. We’ll be bringing on regular guests, and some episodes will have Bob and/or Mike stepping back so others can jump in with their own takes and opinions. We hope you enjoy the change, stick around, and keep growing with us. EPISODE SPONSORS Rigaku Analytical Devices Rigaku provides handheld Raman analyzers for first responders facing unknown hazards.
