I don't doubt it's legit, but I can't for the life of me imagine what the
heck this *gelled / gas-powder Envirogel *could possibly be. Gas? Powder?
Gel? I reckon all we can be sure of is that it's not a liquid! (wonder what
google knows...)
...
Best info I can find is from an EPA doc, describing it as "Gelled Halocarbon
/Dry Chemical Suspension (Envirogel) with ammonium polyphosphate additive".
Recommended as a replacement for Halon 1301 as a flooding agent. Sounds like
it's probably messier than 1301.
