We had a tanker truck full of the stuff overturn a couple weeks ago in a remote area and I got a call from the hazmat guys about running a calcium gluconate line if the stuff escaped containment. (I work for the health department.) They usually use oral tape, but they were worried it wouldn't work fast enough and they couldn't get medical aid fast enough since the nearest hospital to the truck was about 80 miles away.

Fortunately they were able to right the truck without any spilling.

That one you probably _do_ want a Prop 65 notification for ...
