[Hazard --Event] Fire -- fromgas dispensingequipmentafter vehiclecollisiondamage [Consequences] The high line pressure meansthat large amounts of fuel canbe released quickly. [Knowledge] Engineering design for crashprotection is reasonably well-known and can be applied tomitigate this hazard. [Background] 
Piping from the compressor to the dispenserhas pressures of 3000-4000 psig. Whilefueling island collisions may be rare, there isthe potential to release large amounts of fuel.
