The Getty has an endowment in the billions and an entire team devoted to this that is permitted to be on site, coordinates with local fire and police services, etc. The entire center is also built into the hillside, with fireproof vaults in the underground levels, so there is no real risk to any of the collections.
An observation on how this has become extremely common nowadays.
Here, at work, in real life. People just argue with whatever dumb thing they can come up with, for the sake of arguing, it makes them feel smart. It's really hard to have a meaningful conversation with them.
I go to a couple philosophical discussion groups and the occasional town hall meeting. People just can't get their imaginary needs satisfied.
"But that area seems unsafe"
"We could hire a security guard to be around"
"But what if the security guard is a criminal, like in that one episode of muh favorite tv show"
"We could do an extensive background check, work with companies that have a good reputation, ..."
"But what if they make all that up, I saw that in a movie"
And nothing. ever. gets. done.
Btw, I've even seen people get a small round of applause by their peers after making one of such arguments irl. This comes to mind: https://www.youtube.com/watch?v=kn200lvmTZc.
Yes: you can notice this, for example, in the announcements they put out while the area around the Getty Villa evacuated and then burned, where they pointed out that non-emergency staff had evacuated. Similarly, I think JPL always had (emergency) staff present, and their own firefighting resources.
Having heard about wildfire policies for some high-profile institutions in fire-prone areas, they'll often have their own procedures, in coordination with local authorities, which may not involve evacuating when others do, and may involve people coming to the site when others are evacuating.
I imagine they have a number of life-support systems to ensure the staff can hang out in the building for a while in case of a severe natural disaster.
