Sprinkler design density is the water application rate a sprinkler system is engineered to deliver, commonly in the 0.15-0.20 gpm per square foot range for parking occupancies. In a parking facility:
- Density plus duration determines water supply; EV fire behavior argues for honoring both, not for exotic agents.
Considerations
- The design decision is canonical across fire protection, EV charging areas, and response planning. The answer to the modern car fire is still water, delivered by design.
