Classification of Explosives

 

1.2 Explosives are divided into eight classes, as follows:

 

Class 1. - Gunpowder class.

Class 2. - Nitrate mixture class.

Class 3. - Nitro-compound class.

Class 4. - Chlorate mixture class.

Class 5. - Fulminate class.

Class 6. - Ammunition class.

Class 7. - Fireworks class.

Class 8. - Miscellaneous class.

 

1.3 When an explosive falls within the description of more than one class, it shall be deemed to belong exclusively to the class with the highest number.

 

Class 1. - Gunpowder Class

 

1.4 The term "gunpowder" shall include blasting powder and shall mean exclusively gunpowder ordinarily so-called, consisting of an intimate mixture of saltpetre (potassium nitrate), sulphur and charcoal, such saltpetre not containing as an impurity perchlorate of potash in greater quantity than 1 per cent.

 

Class 2. - Nitrate Mixture Class

 

1.5 The term "nitrate mixture" shall mean any preparation. other than gunpowder, formed by the mechanical mixture of a nitrate with any form of carbon or with any carbonaceous substance not possessed of explosive properties whether or not the preparation contains sulphur, and whether or not such preparation is mechanically mixed with any other non-explosive substance, The nitrate mixture class shall comprise such explosives as Anfex and explosives containing a perchlorate and not included in Class 3, Class 4 or Class 5.

 

Class 3. - Nitro-Compound Class

 

1.6 The term "nitro-compound" shall mean any chemical compound that has explosive properties, or is capable of combining with metals to form an explosive compound, and which is produced by the chemical action of nitric acid (whether mixed or not with sulphuric acid) or of a nitrate mixed with sulphuric acid upon any carbonaceous substance, whether such compound is mechanically mixed with other substances or not.

 

The nitro-compound class shall consist of two divisions:

Division 1 shall comprise such explosives a dynamite, blasting gelatine, cordite, dynagel, gelignite, monobel, ajax, saxonite, freflo, and any chemical compound or mechanically mixed preparation that consists either wholly or partly of nitroglycerine, or of some other liquid nitro-compound.

Division 2 shall comprise such explosives as gun-cotton, nitro-cotton picrates, picric acid, trinitrotoluene, slurry explosives such as Sinex and any nitro-compound that is not included in Division 1.

 

Class 4. - Chlorate Mixture Class

 

1.7 The term "chlorate mixture" shall mean any explosive containing a chlorate.

The chlorate mixture class shall consist of two divisions:

Division 1 shall comprise any chlorate preparation which consists partly of nitro-glycerine or of some other liquid nitro-compound.

Division 2 shall comprise any chlorate mixture that is not included in Division 1.

 

Class 5. - Fulminate Class

 

1.8 The term "fulminate" shall mean any chemical compound or mechanical mixture, whether included in the foregoing classes or not, that by reason of its great susceptibility to detonation is suitable for employment in percussion caps or any other appliance for developing detonation, or that by reason of its extreme sensitiveness to explosion and its great instability (that is to say readiness to undergo decomposition from very slight exciting causes) is especially dangerous.

The fulminate class shall consist of two divisions:

Division 1 shall comprise such compounds as the fulminates of silver and mercury, and preparations of these substances; any preparations consisting of a chlorate with phosphorus or certain descriptions of phosphorus compounds, with or without the addition of carbonaceous matter; and any preparation consisting of a chlorate mixed with sulphur or with sulphide, with or without carbonaceous matter.

Division 2 shall comprise such substances as the chloride and the iodide of nitrogen, fulminating gold and silver, lead azide and lead styphnate.

 

Class 6. - Ammunition Class

 

1.9 The term "ammunition" shall mean an explosive of any class when enclosed in any case or contrivance or otherwise adapted or prepared so as to form a cartridge or charge for small arms, cannon, or any other weapon, or for blasting, or to form any safety or other fuse for blasting or for shells, or to form any tube for firing explosives or to form a percussion cap, a detonator, a shell, a torpedo, a war rocket, a railway detonator (fog signal) or other contrivance other than a firework. The ammunition class shall contain three divisions:

Division 1 shall comprise exclusively safety cartridges, safety fuses for blasting. railway detonators (fog signals) and percussion caps.

Division 2 shall comprise urn ammunition that does not contain its own means of ignition, such as cartridges and charges for cannon, shell, mines, or ether like purpose, electric fuses, electric printers, fuse lighters, instantaneous fuse and war rockets, if such rockets do not contain their own means of ignition.

Division 3 shall comprise any ammunition that contains its own means of ignition, and is not included in Division 1. such as detonators, percussion caps not included in Division 1, friction tubes, percussion primers, fuses for shell f such as time and percussion fuses), if such fuses contain their own means of ignition.

Note - Ammunition containing its own means of ignition shall mean ammunition that has an arrangement, whether attached to it or forming part of it, that is adapted to explode or fire it by friction or percussion.

 

Class 7. - Fireworks Class

 

1.10 The term "firework" shall comprise firework composition and manufactured fireworks.

The fireworks shall consist of two divisions:

Division 1 shall comprise firework composition, which term shall mean any chemical compound or mechanically mixed preparation of an explosive or inflammable nature that is used for the purpose of making manufactured fireworks and is not included in any other class of explosive, and also any star and any coloured fire composition that is not included in Division 2.

Division 2 shall comprise manufactured fireworks, which term shall mean an explosive of any class and any firework composition, when such explosive or composition is enclosed in any ease or contrivance, or is otherwise manufactured or adapted for the production of pyrotechnic effects or pyrotechnic signals or sound signals, such as flights of rockets, mines, rockets, serpents, shells, rocket distress signals, Very’s signals, wheels and coloured fire compositions when such compositions are of a nature not liable to spontaneous combustion, and in a quantity not exceeding 500 grams enclosed in a substantially constructed, hermetically closed metal case.

Note - Manufactured fireworks that are not liable to explode violently and which do not contain their own means of ignition shall be classed as "Shop Goods", such as firework showers, flashlight powders, fountains, golden rain, gerbs, lawn lights, pin wheels, devil-among-tailors, Roman candles, sparklers, toy caps, volcanoes, Chinese crackers when the length does not exceed 80 millimetres and the diameter 15 millimetres, and mines, Jack-in-the-boxes and Feu de Joie, not exceeding 500 grams gross mass and rockets not exceeding 120 grams.

 

Class 8. - Miscellaneous

 

1.11 This class shall comprise miscellaneous materials not included in any of the other classes, which have been declared explosives, e.g. matches, Bengal matches, chlorates, ammonium nitrate.

 

Categories of Explosives

 

1.12 For the purpose of Safety Distances in connection with the issue of licences for factories and magazines, all authorised explosives shall be categorised either X, Y, Z or ZZ. These categories shall be defined as follows:

 

Category X. Explosives having fire or slight explosion risk or both, with only local effect.
Category Y. Explosives having mass fire risk, or moderate explosion risk, but not mass explosion risk.
Category Z. Explosives having mass explosion risk with serious missile effect.
Category ZZ. Explosives having mass explosion risk with minor missile effect.
