With this stuff, don't worry about saltSalt water will kill vegetation. I don't know that is their excuse though. I was just trying to think of something that the California environmental department could come up with.
You can't save people because you can kill the vegetation. But the fire is going to kill it? Yeah well, shut up and do as you are told. They run storm water back to the ocean and pipe in water from hundreds of miles away to use. Doesn't make sense but.... California.
Pressure-treated lumber can contain a variety of chemicals, including:
- Chromated arsenicals (CCA): A strong preservative that contains chromium, copper, and arsenic. CCA was commonly used in outdoor residential settings from the 1970s to the early 2000s. While CCA is not on the Environmental Protection Agency's (EPA) list of known or suspected carcinogens, arsenic is a known human carcinogen.
- Alkaline copper quaternary (ACQ): A bactericide, fungicide, and insecticide that doesn't contain chromium or arsenic. ACQ is considered safe for residential use.
- Copper azole (CA): An antifungal and anti-termite agent that's generally considered safe for indoor and outdoor residential use.
- Imidacloprid: Kills insects
- Dichlorooctylisothiazolinone (DCOI): Kills fungi and bacteria
- Tebuconazole: Fights off copper-tolerant fungi
- Propiconazole: Fights off copper-tolerant fungi
