Sec. 4.
(a) All
				containers shall be equipped with a fixed liquid level gauge.
(b) All containers with a capacity of two
				hundred fifty (250) gallons or more shall be equipped with a
				pressure-indicating gauge having a dial graduated from zero (0) to four hundred
				(400) psig.
(c) The filling
				connection shall be fitted with an approved positive shutoff valve in
				conjunction with either an internal backpressure check valve or an internal
				excess flow valve.
(d) All
				containers with a capacity of two hundred fifty (250) gallons or more shall be
				equipped with an approved shutoff vapor valve.
(e) All vapor and liquid connections, except
				pressure relief valves and those specifically exempted in
				355 IAC
				3-2-5(c)  and
				355 IAC
				3-2-5(d), shall be equipped with
				approved excess flow valves or may be fitted with approved quick-closing
				internal valves, which, except during operating periods, shall remain
				closed.
(f) Fittings shall be
				adequately 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 encloses the pressure relief valve,
				the valve shall be properly vented through the guard. The design of the roll
				cage shall prevent pockets of standing water or ice that might pit or erode any
				portion of the container, valves, gauges, or appurtenances. The following are
				requirements for containers:
(1) Containers
				with head mount roll cages used for the field application of ammonia shall have
				roll cage protection extending three hundred sixty (360) degrees in the
				vertical plane transverse to the direction of application such that all valves,
				gauges, and appurtenances, including any attached hose end valve, nozzle, and
				hose fitting, are protected from physical impact by the tongue of the wagon
				(running gear) striking said valves, gauges, and appurtenances, including
				instances whereupon the tongue may be deformed around the front head of the
				container.
(2) For nurse tank
				containers constructed with recessed domes for vapor relief or other valves,
				the wall thickness of the domes shall be measured every ten (10) years by
				properly equipped personnel, qualified to perform nondestructive examination,
				in order to determine if the wall thickness has deteriorated to an unsafe
				condition. If testing determines that repair or alteration has become
				necessary, it shall be done in accordance with the National Board Inspection
				Code, by a firm holding a valid Certificate of Authorization to use the Repair
				Symbol from the National Board of Boiler and Pressure Vessel Inspectors. The
				repair or alteration shall be completed in accordance with
				355 IAC
				3-2-2(b).
