Trees used indoors for the holidays account for approximately 400 fires annually, resulting in 10 deaths, 80 injuries and more than $15 million in property damage. These videos demonstrate how quickly the fire can develop when a DRY tree is exposed to an open flame. These videos are developed by National Institute of Standards and Technology, and are made available in the public domain.
Properly maintain your cut Christmas tree to maintain a high moisture content in the needles of the tree. This will help to limit accidental ignition and prevent a rapid flame spread fire from developing in your home. A tree which has dry needles can readily ignite and generate heat release rates that are capable of causing flashover in residential sized rooms. Watch this video to see just how rapidly the fire spreads!
Now, See the difference between how rapidly a dry tree ignites compared to a properly hydrated tree:
This video show a dry tree fire in non-sprinklered room. The camera view is from the couch
Now, see what a difference there is when residential sprinklers are installed in your home! Think about the prior videos, and how much fire and how much damage there will be to your home by the time the fire department arrives to fight the fire. This is a good reason to install fire sprinklers in your home!
