Any information about the Pacific Palisades Fire

[fintstone]

Too bad it was not contained before it was a raging inferno. Pretty much all fires start out small.

I think it was the historic winds we had that day (and into Wednesday) that made the difference. It's pretty unheard of to have winds of 40, 60, and (gusts of) 100 mph around here. And then to have had them for 2 days straight was a killer.

You are correct that they all start with a spark but this one only stayed small for a few minutes and it was growing rapidly from the first seconds, most likely. It was a perfect storm of hurricane force winds combined with dry vegetation.

Obviously it's cool if someone was able to save their house but you are 100% correct...it's going to be sad when they find additional victims who did not evacuate and succumbed to smoke, then burned up.

The market for rental houses on the westside and other desirable areas was already white hot before the fires and now it's going parabolic. The newly homeless from the Palisades are not poor people. Some landlords are either not aware of the anti-gouging laws during a state of emergency or they are such criminal scumbags that they don't care. I hope a few go to jail.

Then he left. He came back after the worst of the fire passed and put out some lingering flares in the neighborhood.
So he wasn’t some moron who “saved his house” because he defied orders, as the title implies. He was a pretty smart guy who prepped his house and gtfo.

^^^^ One of the less than 1% (like Seahawk) of the population there now tho'. With the knowledge and the means .... kudos to him! Folks on this board would fare a lot better than most of the general population too. Be smart and safe ...

Tell me you did not watch the video without actually saying so. This man was prepared and knew what to do. It is incumbent on our elected officials to see to it that everyone in the state has that same knowledge and preparation. Not only did they fail to do this, they actively made the situation more deadly by refusing to follow accepted forest husbandry principles established over centuries. There has been 1(one) water storage project completed in my lifetime, and I am old AF.

If you insist on making asinine comments, the least you could do is know WTF you are talking about. There are a LOT of elected and appointed officials that should go to prison for their negligence

See link below, this type of structure wildfire protection system may have helped in this disaster. It has been available for several years now, interesting to see if anyone in the fire zone had one operating. It appears to use standard lawn irrigation rotors and sprays which are my line of work for the last 26 years. I haven't checked the supply specs but ideally it needs a backup power supply (batteries) and a reserve water supply (cistern) in case of utility loss. These types of sprinklers are ineffective when winds get above 25 mph, too much spray drift.

I had a simple design I dreamed up using a single rooftop mounted Hunter G90 golf course rotor rated at 60 GPM, having a spray radius of 88ft but needs 90psi. a 3hp pump and 3,600 gallons for every head and hour of use!

That video is misleading. The SF Chronicle article is much more detailed and makes it clear he DID evacuate the area.

Looks like about $10 a sq/ft. Seems reasonable in a high risk area.

What happens when the city water pressure drops to nothing or just a trickle, as it did for the Fire Department. It would need a swimming pool and a battery operated pump to survive in the California wildfires.

What happens when the power goes out?

Also, I wonder how many people will not get whatever insurance they have renewed?

[William930t]

A backup power system with solar assist, inverters and battery storage along with a separate water storage (pool or cistern) would be a must.

Q&A from the company.
https://www.frontlinewildfire.com/protect-home-with-roof-wildfire-sprinkler-system/#fire-back

The system can connect to municipal, well, and/or pool water sources. Unlike interior fire sprinklers, the system is dry until activated, meaning the pipes do not hold water when the system is off.

The Frontline controller needs electricity to receive the remote activation signal from the Frontline app. The controller has a built-in battery backup that will be used if the power is out. If power is present the controller will use electricity from your home. If pool or well water is being used, a dedicated pool pump with backup power source (such as a generator or home battery) is required.

The Class A firefighting foam is formulated to make water more effective for preventing fire. Surfactants significantly reduce water’s surface tension and, when mixed with air it surrounds fuel with a thick layer of water. This creates a barrier between the fuel and the fire making the water more effective reducing the amount of water needed to protect your home.

The system will run for 5 to 7 minutes per zone (if multiple zones have been installed on your home). It will then turn off for 30 minutes. After 30 minutes it will cycle through all zones again. As long as the system has access to a water source, it will run like this until it is deactivated.

Designed to run and remain effective with low water pressure, Defense System 2 is constantly measuring and optimizing available water. Our system runs in a series of zones, much like landscaping irrigation systems, so that we can limit the water required at any given time. The use of Class-A foam further reduces the amount of water used. Typically our system will use your home’s primary water source first. If the system senses a drop in pressure it automatically switches to an available secondary water source such as a pool, tank, or well.
