I have no idea why hazmat isn'hyphenateded. But even before I read this, I let it go in copy without the hyphenation last week. Was I lazy, clairvoyant or just feeling generous? (I had to look up the spelling of clairvoyant, and I'm a bit surprised.)

And if tide pool has been around since 1853, I wonder why it's just being added now.
