Hi,
I'm starting up a rectifying and bottling plant. Running into quite a few fire restrictions. My hazmat engineer keeps telling me at 80 proof we are a class 1b flammable although my research indicates class 1c as we are well below 50%. Realizing that I'll be blending down from 192 proof which is a class 1b, does anyone have the answer to this or any dealings with fire codes that are recent? Thank you in advance
