Section 10 - SYSTEMS MOUNTED ON FARM WAGONS (IMPLEMENTS OF HUSBANDRY) FOR THE TRANSPORTATION OF AMMONIA

10.1.1. Containers shall be constructed in accordance with Rule 3.1.

10.2.1. A suitable "stop" or "stops" shall be mounted on the farm wagon or on the container in such a way that the container shall not be dislodged from its mounting due to farm wagon coming to a sudden stop. Back slippage shall also be prevented by proper methods.

10.2.2. A suitable "hold-down" device shall be provided which will anchor the container to the farm wagon at one or more places on each side of the container.

10.2.3. When containers are mounted on four-wheel farm wagons, care shall be taken to ensure that the weight is distributed evenly over both axles.

10.2.4. When the cradle and the container are not welded together, suitable material shall be used between them to eliminate metal-to-metal friction.

10.3.1. All containers shall be equipped with a fixed maximum liquid level gauge.

10.3.2. All containers with a capacity exceeding 250 gallons shall be equipped with a pressure gauge having a dial graduated from 9-400 psi.

10.3.3. 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 positive shut-off valve in conjunction with either an internal back-pressure check valve or an internal excess flow valve.

10.3.4. All containers with a capacity exceeding 250 gallons shall be equipped for spray loading or with an approved vapor return valve.

10.3.5. All vapor and liquid connections, except safety relief valves and those specifically exempt in 2.4.5.6, shall be equipped with approved excess flow valves or may be fitted with quick-closing internal valves which, except during operating periods, shall remain closed.

10.3.6. Fittings shall be protected from physical damage by means of a rigid guard designed to withstand static loading in any direction equal to twice the weight of the container and lading using a safety factor of four (4) based upon the ultimate strength of the material used. If the guard is fully enclosed, the safety relief valves shall be properly vented through the guard.

10.3.7. If a liquid withdrawal line is installed in the bottom of a container, the connections thereto, including hose, shall not be lower than the lowest horizontal edge of the farm wagon axle.

10.3.8. Provision shall be made to secure both ends of the hose while in transit.

10.4.1. There shall appear on each side and on the rear end of the container in letters at least four inches high, the words "ANHYDROUS AMMONIA".

10.5.1. Farm wagons (Implements of Husbandry) shall conform with State Regulations.

10.5.2. All farm wagons shall be securely attached to the vehicle drawing them by means of drawbars supplemented by suitable safety chains.

10.5.3. A farm wagon shall be constructed so that it will follow substantially in the path of the towing vehicle and will prevent the towed farm wagon from whipping or swerving dangerously from side to side.

10.5.4. All farm wagons shall have five (5) gallons or more of readily available clean water, one pair of tight fitting goggles or full face shield, and one pair of protective gloves.
