Is The bulkhead partition between the engine and passenger compartments designed to prevent compartment fire travel?

Yes, the bulkhead partition between the engine and passenger compartments in vehicles is designed, in part, to prevent or at least significantly slow the travel of fire from the engine compartment to the passenger compartment. It's a crucial safety feature. While not entirely fireproof, it's made of fire-resistant materials to buy time for escape and allow fire suppression systems to work.
