I believe that she probably heard to mix formalin with ammonia solution, not bleach as a deactivating agent. Generally, the ammonia solution is used as a mopping solution for small spills of formalin, not as a mixing agent for substantial spills.

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."
