PACKING GROUP:-

UNIT 4 – IDENTIFICATION

 4.1 LIST OF DANGEROUS GOODS

 The following List of Dangerous Goods, commonly known as the "Blue Pages" each column is explain details.

4.2 Selecting the Proper Shipping Name

Four types in preferred order to use:

1. Single entries for well-defined substances or articles for example

Kerosene                                                              UN 1223

Isopropyl butyrate                                              UN 2405

2.  Generic entries for a well-defined group of substances of articles example

      Adhesives                                                           UN 1133

      Organic peroxide, Type C, liquid                    UN 3103

      Paint related material                                       UN 1263             

      Triazine pesticide, liquid, toxic                        UN 2998

3. Specific n.o.s. entries covering  group of substances or articles of a particular chemical or technical nature, for example

            Refrigerant gas, n.o.s.                                  UN 1078

            Selenium compound, solid, n.o.s. *             UN 3283

 4. General n.o.s. entries covering a group of substances or articles meeting the criteria of one or more classes or divisions, for example

 

      Corrosive solid, n.o.s. *                                       UN 1759

      Toxic liquid, organic, n.o.s.                                 UN 2810

      

4.3 – Mixtures and Solutions not listed by Name

Example:

Acetal is again the hazardous constituent in a mixture. But now, based on tests, Packing Group III has been established for this mixture.

the Hazard class remains the same, but as there is a change on the packing group, the proper shipping name will be

A mixture of one listed substance and one or more non-dangerous goods

Must be identified by the shipping name of the DGs, supplemented with

"Mixture" or "solution", unless:

 

•        The mixture is specifically identified by name                                                                           •        The entry in the List of DGs is for the pure substance only;

•        The hazard class, packing group or physical state differs from listed entry; •        There is significant change to emergency measures

Or Flammable liquid, n.o.s. (Acetal solution)              (UN 1993, CLASS 3, 

Or Flammable liquid n.o.s. (containing Acetal)           Packing Group III)

 

1. MIXTURES AND SOLUTIONS WITH, MULTIPLE HAZARDS

Example:

A liquid mixture consisting of the components Caprylyl chloride and N,N-Dimethylformamide

The mixture meets the criteria of: Class 8, Packing group II and Class 3, Packing Group III

Class 8 is shown at the intersection of: Line 3 III and Column 8(I) II.

This means:                  Primary Hazard:            Class 8, Corrosive liquid

                                      Subsidiary Hazard:        Class 3, Flammable liquid

                                      Packing Group:              II     The most stringent of the packing groups, in this example Packing Group II (medium danger) will apply   

UNIT 5-PACKING REQUIREMENT

DGR section 5 explains how dangerous goods must be packed.

The packing instructions in DGR Section 5 give the maximum permissible quantity per inner packaging.

The maximum net quantity permitted in each package is shown in the list of Dangerous Goods

 5.1 PACKAGING DEFINATION-

 •                 Inner packaging – a packaging for which an outer packaging such as a box or carton is                   required for transport.

•        Outer packaging- the part of packaging seen by the carrier that protects the inner packaging during transport.

•        Package- the packaging plus the content (dangerous goods)

       Overpack- an Overpack is an enclosure used by a single shipper to contain one or more                       packages for convenience in handling stowage.

5.2 PACKAGING-

The following types of packaging are used to ship dangerous goods, other than radioactive material:

•        UN Specification Packaging

•        Limited Quantity Packaging

•        Excepted quantity packaging

•        Other Packaging

Types of Packaging's

Combination Packaging- these packaging's consist of one or more inner packaging's contained in one outer packaging's.

 

Single Packaging's- in these packaging's the article is enclosed in a single container. For example, a drum, a jerrican or a composite packaging.
