| Subclass
1.1 |
Consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously.
|
| Subclass
1.2 |
Consists of explosives that have a projection hazard but not a mass explosion hazard.
|
| Subclass
1.3 |
Consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or, both but not a mass explosion hazard.
|
| Subclass
1.4 |
Consists of explosives that present a minor explosion hazard. The explosive 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.
|
| Subclass
1.5 |
Consists of very insensitive explosives. This division is comprised of substances which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport
|
| Subclass
1.6 |
Consists of extremely insensitive articles which do not have a mass explosive hazard. This division is comprised of articles which contain only extremely insensitive detonating substances and which demonstrate a negligible probability of accidental initiation or propagation.
