Section 355IAC3-6-7. Liquid withdrawal and transfer hoses
-
(a) No liquid transfer hose shall be joined between any nurse tank unit and any tool bar during transport upon a public right-of-way.
(b) During field-application and transportation, no liquid transfer hose of any nurse tank unit, which is mounted upon a single running gear, shall be joined to another nurse tank unit mounted on a separate running gear.
(c) During field-application, any nurse tank unit, pulled in conjunction with another nurse tank unit, shall be equipped with an individual, properly installed breakaway device.
(d) A liquid withdrawal line shall not be installed in the bottom of a container on any nurse tank used in conjunction with tool bars for the field-application of ammonia except in conformity with section 4(f) of this rule.
(e) The following requirements apply when liquid transfer hoses are permanently attached to nurse tank units:
(1) Only the end of the liquid transfer hose, which is attached to a male acme-threaded fitting of the tool bar breakaway device, shall be equipped with a straight-type hose end valve with a bleeder valve on its coupling side.
(2) The hose end valve specified in subdivision (1) shall not be attached to a container fill valve of the same nurse tank unit.
(3) A dummy acme adapter or parking plug shall be provided on the roll cage of a single container nurse tank unit or at a safe location on the running gear of a twin container nurse tank unit. The dummy acme adapter or parking plug shall be welded into a position that prevents either end of the hose from being kinked or stowed under undue strain. The hose end valve of the liquid transfer hose shall be connected to said dummy acme adapter or parking plug at all times except when the transfer hose is used for field-application or other active transfer of ammonia through the hose end valve.
(4) On single container nurse tank units, one (1) end of the transfer hose shall be directly attached to the outlet of the liquid withdrawal valve.
(5) On twin container nurse tank units, one (1) end of the transfer hose shall be directly attached to the manifold shutoff valve. A properly sized excess flow valve shall be provided on the tank side of the manifold shutoff valve. The nominal pipe threads of the hose shall pass through the protective bulkhead for the shutoff valve.
(f) The following requirements apply when liquid transfer hoses are not permanently attached to nurse tank units:
(1) On single container nurse tank units, a male acme-threaded fitting shall be provided on the outlet of the liquid withdrawal valve.
(2) On twin container nurse tank units, a male acme-threaded fitting shall be provided on the outlet of the manifold shutoff valve. A properly sized excess flow valve shall be provided on the tank side of the manifold shutoff valve. The nominal pipe threads of said acme-threaded adapter shall pass through the protective bulkhead for said shutoff valve.
