The author looks at the warnings accompanying sand:  prolonged exposure causes cancer, it can only be used in a fume hood, and - let’s post this on the beach - people who come in contact with sand should  “Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.”.

He also sites the situation where a bridge in SF was shut down while a special squad was called in to clean up a hazardous spill of iron oxide - aka “rust” - because the MSDS said you had to have protective gear to handle it.

*** Anna -ism ***

I realize that no one actually reads my posts unless I put some Anna news in, so here it is.  Anna likes to pretend to be a monkey, and Will likes to pretend he’s a dog.  I was refilling the water bowl for our real canines and the kids wanted to know why Porter was drinking the way he did - lapping with his tongue.  After I explained, Anna then noted that William will be able drink this way once he grows up and becomes a real dog. ;)
