The serial number for each cylinder must be recorded as part of the life-saving appliance service record by the U.S. Coast Guard-approved servicing facility. TP3 The maximum degree of filling (in %) for solids transported above their melting points and for elevated temperature liquids shall be determined by the following: Where: df and dr are the mean densities of the liquid at the mean temperature of the liquid during filling and the maximum mean bulk temperature during transport respectively. While columns 8 and 7 of the Hazardous Materials Table are used to determine authorized packaging for most HazMat (more on that in a little bit), some methods of transportation, HazMat quantities, and specific operations rely on other methods. TP38 Each portable tank must be insulated with an insulating material so that the overall thermal conductance at 15.5 C (60 F) is no more than 1.5333 kilojoules per hour per square meter per degree Celsius (0.075 Btu per hour per square foot per degree Fahrenheit) temperature differential. The purpose of this article is to explain the meaning of the coding system for the Special Provisions of column 7 in order to facilitate your review and understanding of them and how they may apply to your shipment of a hazardous material. Others such as copper and silver are available in trace amounts. TP22 Lubricants for portable tank fittings (for example, gaskets, shut-off valves, flanges) must be oxygen compatible.

The article, machinery, or apparatus, if unpackaged, or the packaging in which it is contained shall be marked Dangerous goods in articles or Dangerous goods in machinery or Dangerous goods in apparatus as appropriate, with the identification number UN3363. Column 7 specifies codes for special provisions applicable to hazardous materials. (7) A code containing the letter T refers to a special provision which applies only to transportation in UN or IM Specification portable tanks. When a specific portable tank instruction is specified by a T Code in Column (7) of the 172.101 Table for a specific hazardous material, a specification portable tank conforming to an alternative tank instruction may be used if: (A) The alternative portable tank has a higher or equivalent test pressure (for example, 4 bar when 2.65 bar is specified); (B) The alternative portable tank has greater or equivalent wall thickness (for example, 10 mm when 6 mm is specified); (C) The alternative portable tank has a pressure relief device as specified in the T Code.
