I think you're refering to Trioxane. It is also toxic. The package warns it is "harmful if swallowed" and "to avoid contamination of food by loose powder. Cleanse hands after handling."

I used some last night in an experiment in my kitchen. I put my Esbit stove on top of my real stove and turned the fan on. That should take care of most of the toxicity issues. Also, I think that as long as you don't breath the fumes straight from the flame or use this stuff in a tent it won't be too bad.
