Test 7 - EO Markings Flashcards
What are the DG Classes?
1 - Explosives 2 - Gases 3 - Flammable Liquids 4 - Flammable Solids 5 - Oxidising substances & organic peroxides 6 - Poisonous and infectious substances 7 - Radioactive substances 8 - Corrosive Substances 9 - Miscellaneous dangerous substances
Define HD 1.1?
HD 1.1 - BLAST
- Contains ammo which presents a mass explosion hazard, which will produce severe structural damage to buildings in the immediate surroundings.
- Severity of damage is dependent upon the quantity of explosives and distance of the buildings from ES.
- Blast and HV frag are the major hazards, may be a danger from heavy frag propelled from the structure in which the explosion occurs.
Define HD 1.2?
HD 1.2 Projection Effects
- 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.
- Blast effects will be limited to the immediate vicinity of the exposed site
Define HD Sub divisions 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.
Define HD 1.3?
HD 1.3 – Fire and Radiant Heat
- 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 and others which burn sporadically.
Define HD Sub divisions 1.3.3 and 1.3.4?
HD 1.3.3 – producing a mass fire effect
- consists of the more hazardous items of HD 1.3 which produce a fireball with intense radiant heat, firebrands and some fragments.
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.
Define HD 1.4?
HD 1.4 - no significant Hazard
- Contains ammo with 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 degrade so it will not entirely contain the effects of the ammo
- No frag 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, regardless of the number of items in the package
Define HD 1.5?
HD 1.5 – Blast
- Contains ammunition which although potentially mass explosive, is very insensitive therefore there is very little probability of a transition from burning to detonation.
Define HD 1.6?
HD 1.6 – Fire and Radiant Heat
- Contains extremely insensitive articles which do not present a mass detonation hazard
Define CG A, B and C?
- CG A: Primary Explosive substance
- CG B: Article containing a primary explosive substance and not containing two or more effective protective features e.g. Detonators
- CG C: Propellant explosive substance or other deflagrating explosive substance or article containing such explosive substance e.g. Cart .50cal Ball F1
Define CG D and E?
- CG D: Secondary detonating explosive substance or Black Powder or article containing a secondary detonating explosive substance, without its own means of initiation and without a propelling charge, or article containing a primary explosive substance and containing two or more effective protective features
- CG E: Article containing a secondary detonating explosive substance without means of initiation, with a propelling charge
Define CG F and G?
- CG F: Article containing a secondary detonating explosive substance with its own means of initiation, with or without a propelling charge
- CG G: Pyrotechnic substance, or article containing a pyrotechnic substance, or article containing both an explosive substance and pyrotechnic substance.
Define CG H, J and K?
- CG H: An article containing both an explosive substance and white phosphorus
- CG J: An article containing both an explosive substance and a flammable liquid or gel
- CG K: An article containing both an explosive substance and a toxic chemical agent
Define CG L, N and S
- CG L: Explosive substance or article containing an explosive substance and presenting a special risk needing isolation of each type
- CG N: Articles containing only extremely insensitive detonating substances
- CG S: Substance or article so packed or designed than any hazardous effects arising from accidental functioning are confined within the package unless that package has been degraded by fire e.g. SAA
What can be mixed with CG L?
None
What CG cannot be mixed with CG S?
A, K, L
Define Following DG classes: 1, 4, 5, 9?
1 - Explosives
4 - Flammable Solids
5 - Oxidising substances & organic peroxides
9 - Miscellaneous Dangerous substances
*What is the purpose of Package Markings?
To ensure quick, correct and sufficient identification of contents.
What are the following condition codes: S, SR, SX, R, RR, RX, N, P?
S - Serviceable SR - Serviceable Restricted SX - Serviceable Not in Service R - Repairable RR - Repairable Restricted RX - Repairable Not in Service N - Not Repairable P - Pending
Definition of a Lot?
The product of one run of production of a particular component, mix or blend.
Aims of Lotting / Batching? (5)
- ID a QTY of EO which should give uniform performance
- Reduce Manufacturer’s risk of large scale rejection or warranty claims
- Facilitate the tracing, ID and withdrawal of EO that is life expired or has given unsatisfactory performance
- ID a definite QTY for results of surveillance can be representative
- Facilitate establishment of records.
Define a Batch?
A Batch is a group assembled rounds, which consist of a number of main components and are normally assembled by selected lots of such components.
Ammunition can be formed into local lots providing the ammunition is serviceable, what else must be assured.
- Each Local Lot is confined to nature, type and model
- Quantity is not to exceed normal production Lot qty
What is the current systems of Batching Australia uses for the manufacture of ammunition?
1969 Batching System
