Authority: IC 15-16-1-6; IC 15-16-1-7

Affected: IC 15-16-1-10

Sec. 4.

(a) All containers shall be equipped with a fixed liquid level gauge.

(b) All containers shall be equipped with a pressure-indicating gauge having a dial graduated from zero (0) to four hundred (400) psig.

(c) Nonrecessed container fittings and appurtenances shall be protected against damage by:

(1) their location;

(2) the vehicle frame or bumper; or

(3) protective housing.

The protective housing, if used, shall comply with the requirements under which the containers are fabricated with respect to design and construction and shall be designed to withstand static loadings in any direction equal to twice the weight of the container and attachments when filled with the lading using a safety factor of not less than 4, based on the ultimate strength of the material to be used. The housing shall be protected with a weather cover, if necessary, to ensure proper operation of valves and safety devices.

(d) Filling connections shall be provided with approved automatic valves to prevent backflow in case the filling connection is broken, except that where the filling and discharge connect on a common opening in the container shell and that opening is fitted with a quick-closing internal valve as specified in subsection (e) the automatic valve shall not be required.

(e) All other connections to containers, except pressure relief valves and those specifically exempt in 355 IAC 3-2-5(c) and 355 IAC 3-2-5(d), shall be provided with approved excess flow valves or in lieu thereof may be fitted with approved quick-closing internal valves, which, except during delivery operations, shall remain closed. The control mechanism for such valves may be provided with a secondary control remote from the delivery connections, and such control mechanism shall be provided with a fusible section (melting point two hundred eight (208) degrees Fahrenheit to two hundred twenty (220) degrees Fahrenheit), which will cause the internal valve to close automatically in case of fire.

(f) All containers shall be equipped with an approved vapor return valve of adequate capacity.
