In WP1, most of the transport information is maintained on the DG Specification (DG_CL_SUB). Below is a description of what is maintained each class of the DG_CL_SUB property tree. This data is then passed to the products using inheritance links.

DG_CL_SUB Property Tree (DG_CL_TREE)

• Dangerous Goods Classification
  

An LS_UN_SUB specification is entered in the “Specification” column for each regulation. In the “RiskPotent” column, a packing group is entered (sometimes with other extra information) for each regulation. In a column all the way to the right, a “10” is entered for each regulation in order to indicate a “Released” status for each regulation.

• Hazard Inducers
  • In WP1, this class maintains technical names, marine pollutant ingredients, and RQ ingredients (DOT) using PURE_SUB specifications unlike PF7, which used dedicated technical name DG specifications. WP1 is also different from PF7 in that in WP1, the technical names are maintained on the DG_CL_SUB level and passed to the products through inheritance, while in PF7 the technical names were stored directly on each product. This leads to maintaining a DG_CL_SUB for each different set of technical names for each UN Number. For example, in PF7, only one DG Specification for UN1993 PG III would be required. Then on each product, a the different technical names would be maintained as necessary (e.g. Product A with “ethanol” and Product B with “acetone”). In WP1, separate DG Specifications would be needed (e.g. one for UN1993 PG III with technical name “ethanol” and one for UN1993 PG III with technical name “acetone”).
  • In general, the technical names will be maintained in IMDG H1 and H2, and they will be used for the description of goods for all regulations. If there is the case that a regulation has a different technical name than IMDG, then in that case the different technical names should be maintained in that specific regulation’s hazard inducers (e.g. DOT H1 and H2 or TDG H1 or H2, etc.).
  • Similarly, the Marine Pollutant ingredients will be stored in IMDG M1 and M2. If M1/M2 is different for another regulation, it can be entered in that regulation and will be ready in priority instead of the IMDG entry.
  • In the description of goods, the technical names portion is constructed using these hazard inducers. For all regulations except DOT and TDG, the technical names will be displayed in the format of (H1, H2, M1). If in the case the primary or secondary hazarding inducing ingredient is the same as the marine pollutant ingredient, the marine pollutant entry will be suppressed so that the same ingredients is not repeated. In other words, if M1 = H1 or M1 = H2, then M1 will be suppressed. For DOT and TDG, M1 will never appear in the technical names. The technical names for these two regulations will only show H1 and H2. M1 and M2 entries will be used to showed the Marine Pollutant ingredients in the description of goods after the phrase “Marine Pollutant” on the BOL and other transport documents.
  • RQ is only relevant for DOT, so the RQ ingredients will always be maintained in DOT R1 and R2. The entries in DOT R1 and R2 will never be displayed as part of the technical name, so in the case of a classification that is solely due to RQ, the ingredients will need to be entered in both DOT H1/H2 and R1/R2.
  • Further Information for Transport (SDS)
    • This class is not used.
    • Regulation-Dep. Mixed Loading Groups
      • This class is used only for IMDG to maintain the mixed loading groups. Enter IMDG as the Dangerous Goods Regulation, and choose from the match code the appropriate mixed loading group. If the mixed loading group should be “not relevant”, you must choose this option. If nothing is entered in this class, nothing will show on the SDS. This was done to prevent the accidental incorrect printing of “not relevant” when nothing is entered in this class.

• Dangerous Goods User-Defined Texts
  • This class is used to add additional phrases to the transport information. Commonly used phrases included the following:
    • “The combustible liquid classification only applies when shipped in package sizes >119 gallons.” for NA 1993 classifications.
    • “This product does not sustain combustion when tested in accordance with 49 CFR 173.120 / UN Sustained Combustibility Testing.” for when a product has tested out of the flammability classification using this criteria. Note that if this criterion causes a product to become non-regulated, it will become impossible to show this phrase in Chapter 14. This is why this phrase should also be entered in the Ch 9 Class “Flash Point” so that it will also appear there.
    • Additional Data for Transport
    • Output of Dangerous Goods Information
      • This class if no longer used. If in updating an old DG_CL_SUB there already exists data here, be sure to mark the information in this class with usage “INTERNAL”.
      • Packing and IBC / Tank requirements
        • This class is not used.
      • Placards
        • This class is used to add placards. Normally, on the transport sheet, whatever the label is for a specific class will be duplicated as the placard. Therefore, most of the time, there is no need to put data in the Placards class. The most common time to manually put the placard is in the case of a DOT combustible liquid. This is because this classification only required a placard and no label, so enter the combustible liquid placard here. The other case to use this class is for the “HOT” mark.

Section 14 of SDS Property Tree

There are two classes that are maintained on the product level (PRODCOM) rather than on a DG_CL_SUB.

• Reportable Quantities (US)
  • This quantity, entered in pounds, is truly a product specific number. This is the “RQ trigger” that causes the product to become regulated. The RQ listed chemical will be maintained on the DG_CL_SUB. The RQ level of the substance is from CLEO regulatory data. The RQ Trigger, which is maintained here on the product, needs to be calculated from the RQ level of the chemical and the composition of the product. For example, if a product contains 50% Phosphorus Trichloride, which has an RQ level of 1000 pounds, the RQ trigger to be entered on the product level is 2,000 lbs. This means when the product is shipped in an amount of 2,000 or more pounds, then it will contain 1,000 or more pounds of Phosphorus Trichloride, so it will be regulated for that.
  • Poisonous by Inhalation (US)
    • This class allows for the correct choice of hazard zone A, B, C, or D for a product.
