DANGEROUS GOODS REGULATIONS

 

STATE AND OPERATOR (AIRLINES) VARIATIONS

Some States and operators use their right to be more restrictive than the ICAO technical instructions. These variations are filed with ICAO and IATA.

State Variation: State variations use a three-letter code. Example USG: United States Government

 The variations published by the states (countries) involved in the routing form (State of origin) through (State (s) of transit) and to (State of destination) and the operators (airlines) involved in the transport and the State of the operator are those that must be applied to the shipment.

Example: MYG-01 is a Malaysian Government variation that applies to operators that transport any class of dangerous goods which:

a)      Originated in Malaysia.

b)     Transit through Malaysia

c)      Or destined for Malaysia; and

d)     Are transported by an operator registered in Malaysia wherever it is operating.

Operator Variations: Operator variations use the airlines two letter IATA code. Example FX: Federal Express

Example: OS-01 is an operator variation listed by Austrian Airlines and applies to all dangerous goods consigned for carriage on this airline.

UNIT 3 – CLASSIFICATION

Dangerous goods are divided into 9 classes. Classes are expressed by

 Single digit numbers. Example, Class 7.

Classes 1,2,4,5 and 6 are divided into "Divisions" due to hazard variation within these classes.

Divisions are expressed by 2-digit numbers. The first digit identifies the Class number and the second identifies the variation within the class

Example, Oxidizer is Class 5, Division 1, and is referred to as "Division 5.1"
