UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Sub classes in Class 1
The first four divisions indicate the main type of hazard anticipated in the event of an accident:
1.1 Blast
1.2 Projection effects
1.3 Fire and radiant heat
1.4 No significant hazard
The other two division are substance or article specific.
1.5 Blast
1.6 Fire and Radiant Heat
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Sub classes in Class 4
Class 4.1 - Flammable solids (eg: Matches);
Class 4.2 - Substance liable to spontaneous combustion;
Class 4.3 - Substances emitting flammable gases when wet.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Sub classes in Class 5
5.1 - Oxidising Substances (Ammonium Nitrate).
5.2 - Organic Peroxides (MEKP).
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Sub class in Class 6
6.1 - Poisonous Substances (CS Bulk).
6.2 - Infectious Substances.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain Class 1.1
- Contains ammunition which presents a mass explosion hazard, which will produce severe structural damage to surrounding buildings in the immediate neighbourhood.
- The severity of the damage is dependent upon the quantity of explosives involved and the distance of the buildings from the explosion site.
- Blast and high velocity fragments are the major hazards although there may be a danger from heavy fragments propelled from the structure in which the explosion occurs.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.2
- Contains ammunition which has a projection hazard but not a mass explosion hazard
- The explosion will result in items burning and exploding a few at a time. Fragments, firebrands and unexploded items may be projected in considerable numbers, some of which may explode on impact and so propagate fire, and/or explosion
- Blast effects will be limited to the immediate vicinity of the exposed site
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.2.1 and 1.2.2
- HD 1.2.1 comprises those munitions that contain a high explosive charge and may also contain a propelling or pyrotechnic charge. These items will have an individual NEQ greater than 0.73kg.
- HD 1.2.2 comprises those munitions that contain a high explosive charge and may also contain a propelling or pyrotechnic charge. These munitions will have an individual NEQ equal to or less than 0.73kg.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.3
- Contains ammunition which has a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard
- Items in this division may explode but do not usually form dangerous fragments. Firebrands and burning containers may be projected.
- It includes some items which burn with great violence and intense heat emitting considerable thermal radiation (mass fire hazard) and others which burn sporadically.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.3.3
- HD 1.3.3 – producing a mass fire effect
- Consists of the more hazardous items of HD 1.3 and are more likely to be bulk packed gun propellants which produce a fireball with intense radiant heat, firebrands and some fragments.
- The firebrands may be only small glowing particles of packaging materials but sometimes there may be massive fiery chunks of burning propellant.
- Ammunition that gives rise to considerable radiant heat
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.3.4
- HD 1.3.4 not producing a mass fire effect
- consists of the less hazardous items of HD 1.3 that produce a moderate fire with moderate projections and firebrands.
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.4
- Contains ammunition with only a moderate fire hazard which will not contribute excessively to the fire
- The effects will be largely confined to the package, however the external fire may cause the package to be degraded such that it will not entirely contain the effects of the ammunition
- No fragments of appreciable size or range are to be expected. An external fire will not cause a mass explosion of the total contents of the package, irrespective of the number of items in the package
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.5
- Contains ammunition which although potentially mass explosive, very insensitive usually when conditions of extreme confinement plus large quantities are involved
- Ammunition in this division is confined to certain types of bulk explosives which are so insensitive that there is very little probability of a transition from burning to detonation under normal conditions of storage and transport
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
Explain 1.6
- Contains extremely insensitive articles which do not present a mass detonation hazard
UN CLASSIFICATION SYSTEM - REMEMBER THIS QUESTION
What is CG
CG signifies compatibility for storage without increasing probability or magnitude of an accident
