The following sections of the Ohio State Fire Code pertaining to the loading and unloading of tank vehicles are hereby adopted:
(a) Loading and unloading of tank vehicles shall only be done in approved locations.
(b) The driver, operator or attendant of any tank vehicle shall not remain in the vehicle but shall not leave the vehicle unattended during the loading or unloading process. Delivery hose, when attached to a tank vehicle, shall be considered to be a part of the tank vehicle.
(c) When transferring Class I liquids, motors of tank vehicles or motors of auxiliary or portable pumps shall be shut down during making and breaking hose connections. If loading or unloading is done without requiring the use of the motor of the tank vehicle, the motor shall be shut down throughout the transfer operations of Class I liquids.
(d) If portable pumps are used for transferring Class I liquids, the portable pumps shall comply with the applicable provisions of Ohio Fire Code Section 5-1 or 5-2.
(e) No cargo tank or compartment thereof used for the transportation of any flammable or combustible liquid or asphalt shall be loaded liquid full. Sufficient space (outstage) shall be provided in every case to prevent leakage from such tank or compartment by expansion of the contents due to rise in temperature in transit and in no case less than one percent (1%).
(f) Delivery of Class I liquids to underground tanks of more than 1,000 gallons (3800 L) capacity shall be made by means of tight connections between the hose and the fill pipe.
(g) In all cases where underground tanks are equipped with any type of vapor recovery system, all connections required to be made for the safe and proper functioning of the particular vapor recovery process shall be made. Such connections shall be designed to prevent release of vapors at grade level and shall remain connected throughout the loading or unloading process.
(h) When a cargo tank is filled through bottom loading, a positive means shall be provided for loading a predetermined quantity of liquid, and an automatic secondary shutoff control shall be installed in each compartment to prevent overfill.
(i) The secondary shutoff control system shall be labeled as to manufacturer and type. Any electrical system shall be labeled as to manufacturer and type. Any electrical system used for secondary shutoff must be in accordance with NFPA 70, National Electric Code.
(j) When bottom loading vehicles are equipped for vapor recovery and vapor recovery is not required, the tank vapor system must be open to the atmosphere to prevent pressurization of the tank and the vapor system.
(k) When a dry disconnect vapor recovery adapter is used, provisions must be made to assure the vapor recovery system is fully vented before unloading to prevent collapse of the tank. This applies to both bottom and top loading.
(l) When bottom loading a tank equipped with a vapor recovery system, the vapor recovery connection must be used to conduct vapor away from the loading area using the terminal vapor recovery system, discharge standpipe, or by opening the tank fill openings (manholes).
(m) When a cargo tank is filled through a top opening, the cargo tank shall be bonded to the fill stem or some part of the rack structure which is electrically interconnected with the fill stem piping.
Exception No. 1: Loading asphalt, crude oil or a product containing substantial proportions of crude residuum.
Exception No. 2: Tank vehicles used exclusively for transporting Class II and Class III liquids when loaded at locations where no Class I liquids are handled.
(n) The bond-wire connection shall be made prior to opening the dome covers. It shall be maintained in place during the entire filling operation and the dome covers shall be securely closed before the bond wire is disconnected from the cargo tank.
Note: Bond wires may be insulated or noninsulated. A noninsulated wire permits ready visual inspection of continuity of bond. Insulated types should be electrically tested or inspected periodically for continuity of the entire bond circuit including clamps and connectors.
(o) No external bond-wire connection or bond-wire integral with a hose is needed for the unloading of flammable and combustible liquids into underground tanks now when a tank vehicle is loaded or unloaded through tight connections such as to an aboveground tank or through bottom connections.
(p) Smoking on or about any tank vehicle while loading or unloading any flammable or combustible liquid is forbidden. Extreme care shall be taken in the loading or unloading of any flammable liquid into or from any cargo tank to keep fire away and to prevent persons in the vicinity from smoking, lighting matches, or carrying any flame or lighted cigar, pipe or cigarette.
(q) No flammable or combustible liquid shall be transferred to or from any tank vehicle unless the parking brake is securely set and all other reasonable precautions have been taken to prevent motion of the vehicle.
(r) Each tank vehicle shall be provided with at least one portable fire extinguisher having at least a 20-B, C rating or, when more than one is provided, each extinguisher shall have at least a 10-B, C rating. Each tank vehicle manufactured after January 1, 1980, shall be provided with at least one portable fire extinguisher having at least a 2-A, 20B-C rating, in lieu of the above. Ratings shall be in accordance with NFPA 10, Standard for Portable Fire Extinguisher.
(s) Fire extinguishers shall be kept in good operating condition at all times, and they shall be located in an accessible place on each tank vehicle. Extinguisher shall be maintained in accordance with NFPA 10, Standard for Portable Fire Extinguisher.
(t) No person shall violate any of the foregoing Code provisions or permit or allow the violation of the foregoing Code provisions upon premises they own, operate or control.
(u) Anyone who is convicted of any violation under this section shall be guilty of a fourth degree misdemeanor which is punishable by a fine up to two hundred fifty dollars ($250.00) and imprisonment up to thirty days.
