Saw this on FNC... thought it was pretty neat so I thought I'd spread the word for anyone who is a little nervous about having a tree in their house that could burst into flames at the drop of a hat or want to take extra fire precautions in their entire home.

No, I'm not getting paid to post this. Just thought it was worth letting people know about.
No, I don't currently use it. Frankly, if my home burned down it'd be a blessing.

Christmas Tree treatment

NO-BURN® CHRISTMAS TREE FIRE GARD was developed for direct application to your live Christmas tree, rendering it highly fire resistant. CHRISTMAS TREE FIRE GARD can also be used on garlands, wreaths and other Christmas decorations. NO-BURN® CHRISTMAS TREE FIRE GARD will not discolor or brown the needles in a live tree, nor will it affect needle retention. It is easily applied and is safe for children and pets. In 2003, the State of Rhode Island, still recovering from the affects of The Station nightclub fire, mandated the use of NO-BURN® CHRISTMAS TREE FIRE GARD on the state Christmas tree in the State Capital Building. Take the same steps to make sure that a Christmas tree fire does not destroy your holiday. USES: Use CHRISTMAS TREE FIRE GARD on live cut Christmas trees, wreaths, garlands, cut centerpieces, and more! TEST RESULTS NO-BURN® CHRISTMAS TREE FIRE GARD has been tested and registered by the California State Fire Marshal per Code Title 19, Section 1264.3 Christmas Trees (it is subject to re-examination, revision and possible cancellation)

It works pretty good.  My brother uses it but then he never had a fire to begin with.  Since he has 2 kids now every little bit helps.

So now your Christmas tree can be non-flammable or non-carcinogenic, but not both at the same time.
