Rule 901:5-3-14. Systems mounted on farm equipment for the application of ammonia

119.03 (A) Design and construction of containers: The minimum design and construction for containers shall be in accordance with rule 901:5-3-03 of the Administrative Code. (B) Mounting of containers: All containers shall be securely mounted. (C) Container valves and appurtenances: (1) Each container shall have a fixed maximum liquid level gage; (2) The filling connection shall be fitted with combination back-pressure check valve and excess flow valve; one double or two single back-pressure check valves; or a position shut-off valve in conjunction with either an internal back-pressure valve or an internal excess-flow valve; (3) An excess-flow valve is not required in the vapor connection, provided the controlling orifice is not in excess of seven-sixteenths of an inch in diameter and the valve is a hand-operated (attached hand wheel or equivalent) shut-off valve. To assist in filling applicator tanks, it is permissible to bleed vapors to the open air, providing the preceding requirements are met; (4) Metering devices may be connected directly to the tank withdrawal valve. A union type connection is permissible between the tank valve and metering device. Remote mounting of metering devices is permissible using hose which meets with the specifications required by rule 901:5-3-08 of the Administrative Code. When the applicator tank is trailed and the metering device is remotely mounted, such as on the tractor tool bar, an automatic break-a-way type, self-closing, coupling must be used; and (5) No excess-flow valve is required in the liquid withdrawal line provided the controlling orifice between the contents of the container and the outlet of the shut-off valve does not exceed seven-sixteenths of an inch in diameter. (D) Safety equipment: Each piece of farm equipment transporting anhydrous ammonia shall carry a container of at least five gallons of water and shall be equipped with rubber gloves and either a full face mask, or a pair of tight-fitting goggles, or one full face shield. The driver shall be instructed in their use and the proper action to take to provide for his safety. (E) Marking of container: There shall appear on the rear and both sides of the container in letters at least three inches high the words "ANHYDROUS AMMONIA." (F) Marking of appurtenances: (1) All container openings, except safety relief valves, liquid level gaging devices, and pressure gages shall be identified by legend or color code as specified in rule 901:5-3-04 of the Administrative Code; and (2) Instructions for loading and unloading procedures shall be required on all containers.
