NOTE 5: Mining devices consisting of a cylinder containing carbon dioxide with a heating element are authorized for shipment under the following conditions: Cylinders shall be of steel, have a calculated bursting pressure of at least 39,000 pounds per square inch, be fitted with a frangible disc that will operate at not over 57 percent of that pressure, be able to withstand a drop of 10 feet so as to strike crosswise on a steel rail while under internal pressure of at least 3,000 pounds per square inch, and be charged with not over 6 pounds of carbon dioxide gas at a filling density of not over 85 percent. (See Note 12 of this section); the cylinders are exempted from specification requirements other than the foregoing; the device must be shipped in strong boxes or must be wrapped in heavy burlap and bound by 12 gauge wire with the wire completely covered by friction tape. Wrapping must be applied so as not to interfere with the functioning of the frangible disc safety device. Shipments must be described as "liquefied carbon dioxide gas (mining device)" and must be marked, labeled, and certified as prescribed for liquefied carbon dioxide. [Note 5 amended by Order 32, 22 F. R. 7837, Oct. 3, 1957]

NOTE 12: Filling density. The term “filling density" shall designate the percent ratio of the weight of gas in a container to the weight of water that the container will hold at 60° F. (One pound of water equals 27.737 cubic inches at 60° F.)

[Note 12 was amended by Order 34, 23 F. R. 2327, Apr. 10, 1958]

NOTE 14: Cylinders having a water capacity in excess of one gallon shall be insulated with three coats of heat-retardant paint, of a type approved by the Bureau of Explosives, applied over suitable primer and finished with suitable waterproof paint; or with other equally efficient insulation approved by the Bureau of Explosives.

[Note 14 was added by Order 35, 23 F. R. 4030, June 10, 1958]

NOTE 15: Spec. 3HT (§ 78.44 of this chapter) cylinders are authorized for aircraft use only, for a maximum service life of 12 years, and must be equipped with safety relief devices as required by § 73.34(f). Only a frangible disc safety relief device, without fusible metal backing, shall be used with spec. 3HT (§ 78.44 of this chapter) cylinders and the rated bursting pressure of the disc shall not exceed 90 percent of the minimum required test pressure of the cylinder with which the device is used. Cylinders must be shipped in strong outside containers.
