Ship onlynonflammable gases in these cylinders and pack in strong outside containers.4. Ship DOT-2P, 2Q, 3E, 3HT, 4BA spherical type, 4D, 4DA, 9, 39, 40, 41, and 4DS spheres and cylinders instrong outside containers.5. When used for shipment of flammable gases, the internal volume of the specification 39 cylinders must not beover 75 cubic inches.6. Ensure each valve outlet is sealed by a threaded cap or a threaded solid plug.7. Ensure DOT-3AL cylinders are equipped with brass or stainless steel valves and cleaned in compliance withFederal Specification RR-C-901c.8. See A6.5.1 and A6.5.5 (except only DOT 2P is authorized).9. See A6.5.5.A6.7. Liquefied Petroleum Gas (see A3.3.2 for additional cylinder and filling requirements).A6.7.1. Use DOT 3, 3A, 3AA, 3AL, 3B, 3E, 4, 4A, 4B, 4BA, 4BW, 4B240FLW, 4B240ET, 4B240X, 4E, 9, 25, 26,38, 39, or 41 cylinders. Ensure the internal volume of DOT 39 cylinders is not over 1.2 L (75 cubic inches). Use ofexisting DOT 3, 4, 4A, 4B240X, 9, 25, 26, 38, and 41 cylinders is authorized, but new construction of thesecylinders is not authorized.A6.7.2. Use cylinders marked as complying with DOT 4B240FLW, bearing manufacturers symbol WCO and serialnumbers 47A-1 to 47A-59200 (inclusive), and varying from the specification requirements for the physicalproperties of steel.A6.7.3. Use DOT 3C or 4C cylinders, when the capacity of cylinders is not over 60.5 L (3,881 cubic inches, 16gallons) with 5 percent tolerance. Do not exceed a gas pressure over 1000 kPa (145 psig) at 55 degrees C (130degrees F). Comply with the requirements of table A6.1 for the gases named.A6.7.4. Use inside metal containers, DOT 2P or 2Q, packed in strong wooden or fiberboard boxes designed toprotect valves from injury or accidental functioning under normal transportation conditions. These containers areauthorized for liquefied petroleum gas with a gas pressure of 241 kPa (35 psig) at 21 degrees C (70 degrees F) and689.5 kPa (100 psig) at 55 degrees C (130 degrees F) (or not over 310.3 kPa (45 psig) at 21 degrees C (70 degreesF) and 724 kPa (105 psig) at 55 degrees C (130 degrees F) when equipped with safety devices which will preventrupture of the container when it is exposed to fire.) Each completed container filled for shipment must have beenheated until contents reached a minimum temperature of 55 degrees C (130 degrees F) without evidence of leakage,distortion, or other defects.A6.7.5. Foreign cylinders meeting the requirements of A3.3.2.7.HA6.8. Fire Extinguishers. Fire extinguishers authorized below may be shipped secured in holders of equipmentand protected from possible accidental damage. If these fire extinguishers are not fastened in a holder designed forthem, pack in strong outer containers.-Ship fire extinguishers in DOT specification cylinders identified in paragraphs A6.8.1 and A6.8.2.-Ship fire extinguishers in non-DOT specification cylinders as identified in paragraphs A6.8.3 and A6.8.4.-Fire suppression bottles in DOT specification 3HT, 4D, 4DA, or 4DS, use description "Liquified Gases,UN1058". See paragraph A6.5.1 and table A6.1.A6.8.1. Use DOT 3A, 3AA, 3AL, 3E, 4B, 4BA, 4B240ET, or 4BW cylinders provided:-Cylinders contain only fire extinguishing agents such as ammonium phosphate, sodium bicarbonate,potassium bicarbonate, potassium imido dicarboxamide and bromochlorodifluromethane orbromotriflouromethane, which is commercially free from corroding components.-Cylinders are charged with a nonflammable, nontoxic, noncorrosive, dry gas, having a dew point at orbelow minus 46.7 degrees C (minus 52 degrees F) at 101 kPa (1 atmosphere), to not more than the servicepressure of the cylinder.-Cylinders have an external corrosion-resistant coating.-Cylinders are retested in accordance with Title 49 CFR 173.34(e)(18).-Fire extinguisher, DOT 4BW240, on a cart does not require additional packaging.A6.8.2. Use DOT 2P or 2Q inner nonrefillable metal containers provided:-The liquid portion of the gas plus any additional liquid or solid does not completely fill the container at 55degrees C (130 degrees F).
