Explosive Substance Compatibility and Classification
(Continued)
In addition to the proper shipping name (correct technical name) and
the UN number, the individual schedules in Class 1 also give the
substance's or article's division and compatibility group.
If you
are the shipper, you must show this information on the package label.
The schedules also show the substance's or article's stowage
category.
You or the personnel you delegate must include this
information in the shipping documentation.
Class 2 - Gases
Gases carried on board ships have varied properties and come in
different forms.
They may be compressed, liquified at ambient
temperature under high pressure, dissolved under pressure in a
solvent which is then absorbed in a porous material, or liquified by
refrigeration.
They may be nonflammable, inflammable, poisonous,
corrosive, combustible, or a combination of all or some of these
things. Some gases are lighter than air; some are heavier.
For the purpose of stowage and segregation on board ship, Class 2 is
further subdivided according to the hazards presented by gases during
stowage and transport:
Class 2.1 - Inflammable* gases
Class 2.2 - Nonflammable gases
Class 2.3 - Poisonous gases
* Flammable has the same meaning.
