Hmm, I have a lot more fire retardant paint left still, so I guess I will keep on going. (siding is painted, working on eaves). The big issue with paint (as usual) is how labor intensive it is, especially on the undersides of the eaves (up on a ladder, arms up...). After it's all painted, will need to cure for 4-5 days before top coat. Intumscent paint, which provides significant protection from ignition. #random#disasterpreparedness#painting#wildfires
@ai6yr@bruce@douglasvb@camless@MsMerope If you want to read a book about what chapparal fires can be like, find a copy of The Esperanza Fire by John N. Maclean. I warn you now it is not a "feel good" story.
@ai6yr@douglasvb@camless@MsMerope The energy released in an acre of chapparal is about equal to a 1 megaton nuclear bomb. The only difference is the bomb releases it in a tiny fraction of a second where the chapparal releases over several minutes depending on wind speed and terrain.
@camless@MsMerope@ai6yr I've been wondering if the fire is already crowning before it gets to your defensible space with the ladder fules removed, does it make much difference? 🤔
I'm thinking about how the Creek Fire blew through the crowns for several miles when it came out of Jose Basin and ran over the top of Pineridge with a multi hundred foot tall wall of flames.
The house of a friend survived in that area because his water storage tank melted and deluged around the house 😬
@douglasvb@camless@MsMerope@ai6yr Several years ago as I recall, the forest service had a big crown fire that was unstoppable until...it hit forest land managed by one of the Apache tribes (white mountain?). The crown fire dropped to the ground because of the tree spacing and became controllable. I don't remember the name of the fire. My Dad said the rule of thumb he used was the forest was thin enough if you could see 100 yards through the trees.
@MsMerope@ai6yr Yep, defensible space does not mean cutting down trees. That's a huge myth that this Administration is perpetuating.
It's ladder fuels, those that allow the flames to climb into canopies. Grasses, shrubs, vines, the GD poison oak that grows in central California...
Like making a fire, it's hard to get a tree to burn, unless it's super dry and surrounded by debris. Just like it's hard to start a large log on fire, it takes steps and hot coals.
@ai6yr Folks should look up Jack Cohen from the Missoula Fire Science Lab, his work has been integral for FireWise and other building resiliency recommendations.
Fun facts about homes and wildfires:
- spraying water on lawns and homes won't stop a flaming front from burning over your home, it'll evaporate long before the front passes. People die each year trying to save their homes. You're more likely to put a camp fire out by pissing into it than using a 3/4 hose that may lose pressure...
- most homes don't burn from 'direct flame impingement', aka the flames touching the house, it's from decks, full gutters, soffits, and vents that are not covered with fine mesh. Same goes for vents under houses
- decks burn if you have debris, wood piles, or shrubs/vegetation too close to the deck. If you keep all debris away, it's harder for them to catch fire. Not impossible, more difficult. Build a stone patio instead.
- mulch beds can convey flames to structures, try to keep a good barrier between your house and the mulch.
