I get that, but the reality is that 40k people were evacuated. Shouldn't zoning be set up so as to prevent that? Light manufacturing in general is fine but it seems like these particular storage tanks might have been a bit too large for that location.
If you are worried about this incident, just wait until you hear about crude-by-rail! Crude is transported through LOTS of residential neighborhoods and zoning doesn’t matter. Additionally, railroads are governed by federal law so states / local munis can’t put additional restrictions on where, when, or speed limits.
Zoning doesn't protect people from chemicals, it protects white people from black and chinese people, and that has always been its only and avowed purpose.
Also notable that the people who live across the street from the tanks don't live in Garden Grove. By a miracle of local agency boundaries, the factory is in Garden Grove but the houses are in Stanton. Welcome to California.

It's funny that you would suggest this about California, where it is notoriously hard to build things.
Accidents happen, it's not obvious that this was a forseeable outcome (happy for corrections from folks who have expertise in this area).
