The provisions of this section apply to tank vehicles which are to be used for the transportation of asphalt or flammable or combustible liquids (hereinafter referred to as "tank vehicles").

    A. 1. Parking on Streets, Avenues, Alleys or Highways in the City. Tank vehicles shall not be parked or left unattended on any street, highway, avenue or alley in the city; provided, that this shall not prevent a driver from the necessary absence from the vehicle in connection with the delivery of his load, except that during actual discharge of the liquids some responsible person shall be present at the vehicle, nor shall it prevent stops for meals during the day or night if the street is well lighted at point of parking. Tank vehicles shall not be parked out of doors at any one point for longer than one hour except at flammable liquid bulk terminals, bulk plants and other locations approved by the city fire marshal.

    2.    Tank vehicles shall not be parked or garaged in any building or structure other than those specifically approved for such use by the city fire marshal.

    B.    Filling and Discharging. The driver, operator or attendant of any tank vehicle shall not leave the vehicle while it is being filled or discharged. Delivery hose, when attached to a tank vehicle, shall be considered to be part of the tank vehicle. When making or breaking hose connections, the motors of tank trucks or tractors shall be shut down. If loading or unloading is done without the use of a power pump, the tank truck or tractor motor shall be shut down throughout such operations. (Ord. 551 § 1, 1981: prior code § 24-5-2(B))
