You may use paints[ it's knowing UN 1263 paint class 3], varnishes etc., and you know that these products are dangerous due to their dangerous characteristics. But you may not know that all mentioned product are classified Flammable liquids Class 3 . In this article you will learn about it:



Class 3  Flammable Liquids

Comprises liquids or mixtures of liquids or liquids containing solids in solution or in suspension ( like my previous examples ), but not including substances otherwise classified on account of their dangerous characteristics) which give off a flammable vapour at temperatures of not more than 60°C closed-cup test or not more than 65.6°C open-cup test normally referred to as the flash point.

 

This hazard class has no subdivisions.

Packing Groups

How to Assign a Packing Group for  any Flammable liquid ?

Some dangerous goods (Class 1, Class 2, Division 6.2 and Class 7) are not assigned into 3 packing groups I, II and III based on the degree of danger they present.

The remaining dangerous goods classes  are assigned into 3 packing groups (also known as UN Packing Group) in accordance with the degree of danger they present.

The packaging requirements for dangerous goods assigned to UN packing group I are much higher than the dangerous goods assigned to packing group II and III.

In this article, we will show you how to assign packing groups for dangerous goods class 3 Flammable liquids.

This table explain the scope of initial boiling points and flash points for each packing group :

Examples: carbon disulphide, isopropylamine.

Packing Group II: Medium danger

Assigned to flammable liquids with a flash point less-than-23°C and an initial boiling point of greater than 35°C.

Examples: petrol, isopropyl alcohol, acetone.

Packing Group III: Low danger

 Assigned to flammable liquids with a flash point greater-than-or-equal-to 23°C but less-than-or-equal-to 60°C and an initial boiling point of greater than 35°C.
