It does remind me of a time when the HAZMAT folks shut down NW Yeon AND St. Helens road because of an unknown white liquid in the street. They shut it down for over eight hours and walked around in protective gear cleaning it up. Essentially they shut down the NW industrial area for most of the business day.
Well, it turned out to be milk that had burped out of the venting system of a milk truck. They attempted to force the company to pay clean up costs, and fine them for not reporting a spill, but the company representative pointed out that no HAZMAT clean up was required and there is no regulation requiring reporting spilled milk. At least in the quantity that was spilled there - I think it was less than a quart. Oh well.
Which proves the old aphorism..."There's no sense crying over spilled milk"!
Haw, haw, haw. Well, _I_ thought it was funny.
