I should have mentioned that Armour does state that the reaction should be performed under a fume hood, with lab coat, goggles, & gloves. The 2nd ed. of her Guide is from 1996, if that makes any difference. -Stefan -----Original Message----- From: DCHAS-L Discussion List [mailto:DCHAS-L**At_Symbol_Here**LIST.UVM.EDU] On Behalf Of Burrill, Jason Sent: Thursday, July 19, 2007 2:23 PM To: DCHAS-L**At_Symbol_Here**LIST.UVM.EDU Subject: Re: [DCHAS-L] formaldehyde and bleach Here is an excerpt of one of my references.

Yes yes - I know formaldehyde is a hazardous waste, blah blah, and treatment isn't allowed, yada yada. I have to head off this biologist before she does any more "chemistry."
