The "three minute response rate" of the maintenance unit is 100.00%, and the "thirty minute arrival rate" is 99.20%. The average time for rescue personnel to arrive at the scene is 10.66 minutes, and the average time for on-site rescue is 5.90 minutes, far below the national standard of 30 minutes for arrival.
