“There was a very odd “smell” thoughout the southside after the explosion and it was still lingering in the wind at 2:00AM. It was NOT the smell of natural gas and it did not have the typical “house fire” smell. It smell almost sweet, floral, but musky. (That’s the best I can describe it.)”
Nitrous Oxide has a faint sweet smell.
But they add Sulfur Dioxide to Nitrous Oxide these days to thwart the huffers...
Hmmm; no laughing matter, here; for sure and 'however'. . .
Acetone peroxide is a favorite of ROP adherents. As any welder knows, acetylene defines the term musky smell.
