Dangerous Goods Class 1| Explosives

Dangerous Goods Class 1 Explosives 1 Explosives are divided to 6 hazmat divisions 1.1,1.2,1.3,1.4,1.5 and 1.6 . in this article on Aviation Professional you will read about each hazmat division and identify explosives DG placards.

In this Hazmat Class 1 Explosives there are Six Divisions, see the table below :

Class No.	Division No.	Name of Division
1	1	Articles and substances having a mass explosion hazard.
1	2	Articles and substances having a projection hazard but not a mass explosion hazard.
1	3	Articles and substances having a fire hazard, a minor blast hazard and/or a minor projection hazard but not a mass explosion hazard.
1	4	Articles and substances presenting no significant hazard.
1	5	Very insensitive substances having a mass explosion hazard.
1	6	Extremely insensitive articles which do not have a mass explosion hazard.

After you get an idea about the names of the six divisions in dangerous class 1, it is important to know the meaning of the letters which always written beside the division number {Example 1.4S}. the letter [s] mean the compatibility group [s].

Compatibility Groups

Dangerous Goods Class 1 are assigned to one of six hazmat divisions, depending on the type of hazard they present and to one of thirteen compatibility groups which identify the kinds of explosive articles and substances that are deemed to be compatible.

Now, let us start with the first hazmat division 1.1

Dangerous Goods Class 1 - Division 1.1

Articles and substances having a mass explosion hazard.

Division	IATA IMP CODE
1.1	REX

DG CLASS 1 - DIVISION 1.1 LABEL

Example

TNT, UN 0209

Compatibility Group(s)

Note : These explosives are normally forbidden for carriage by air.

Dangerous Goods Class 1 - Division 1.2

Articles and substances having a projection hazard but not a mass explosion hazard.

Division	IATA IMP CODE
1.2	REX

Example

MINES, UN 0209

Compatibility Group(s)

Note : These explosives are normally forbidden for carriage by air.

DG Class 1 - Division 1.3

Articles and substances having a fire hazard, a minor blast hazard and/or a minor projection hazard but not a mass explosion hazard.

Division	IATA IMP CODE
1.3	REX
1.3 C	RCX
1.3 G	RGX

WHEN PERMITTED

Example

ROCKET MOTORS, UN 0186

Compatibility Group(s)

Note : These explosives are forbidden for carriage by air.[ With Few Exception]

Note : Only explosives in Division 1.3, compatibility groups C and G are permitted on a cargo aircraft.

Dangerous Goods Class 1 - Division 1.4

Articles and substances presenting no significant hazard. This division comprises articles and substances which present only a small hazard in the event of ignition or initiation during transport. The effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.

Division	IATA IMP CODE
1.4 B	RXB
1.4 C	RXC
1.4 D	RXD
1.4 E	RXE
1.4 G	RXG
1.4 F	REX
1.4 S	RXS

DG CLASS 1 - DIVISION 1.4 LABEL

Compatibility Group(s)

Example

FIREWORKS, UN 0337

Division 1.4 is subdivided into various compatibility groups. The compatibility groups are shown by a letter at the end of the code, for example S. The letter shown on the label may be B,C,D,E,G or S.

Note 1 : Only explosives in Division 1.4, compatibility group S are permitted on a passenger aircraft.

Note 2 : Only explosives in Division 1.4, compatibility groups B, C, D, E, G and S are permitted on a cargo aircraft only.

Dangerous Goods Class 1 - Division 1.5

Very insensitive substances having a mass explosion hazard. which are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport.

Division	IATA IMP CODE
1.5 D	REX

DG CLASS 1 - DIVISION 1.5 LABEL

Example

EXPLOSIVE,BLASTING, TYPE E, UN 0332

D	Compatibility Group(s)

Note : These explosives( 1.5) are normally forbidden for carriage by air

Dangerous Goods Class 1 - Division 1.6

Extremely insensitive articles which do not have a mass explosion hazard. This division comprises articles which contain only extremely insensitive substances and which demonstrate a negligible probability of accidental initiation or propagation.
