The mass of TNT that would produce an equivalent explosive effect to the inventory under consideration.

The Australian Explosives Industry Safety Group (AEISG) publishes a number of Codes of Practice for the explosives industry including a code for Mobile Processing Units (MPU's).

A mass of angular volcanic fragments united by heat.

Vibration of the atmosphere due to the release of explosives energy.

The three main sources of airblast are rock release pulse, stemming release pulse and rock piston effect.

1. Rock release is where the face bursts due to inadequate burden.
2. Stemming release is due to rifling or cratering of the blast hole collar.
3. Rock piston is the large, low frequency, movement of air driven by the movement and swelling of the blasted rock mass.

ALANFO A mixture of ANFO and aluminium powder. Adding aluminium increases the strength. As aluminium is a fuel a reduced quantity of diesel is required.

Ammonium Nitrate (AN), meeting the requirements of UN1942.

The chemical compound ammonium nitrate, the nitrate of ammonia with the chemical formula NH₄NO₃, is a white crystalline solid at room temperature and standard pressure. It is commonly used in agriculture as a high-nitrogen fertilizer, and it has also been used as an oxidizing agent in explosives, including improvised explosive devices. It is the main component of ANFO and emulsion explosives which account for over 80% explosives used in Australia.

AN used for ANFO manufacture is referred to as PPAN meaning Porous Prilled Ammonium Nitrate.

Prilled is the term for a small aggregate of a material, most often a dry sphere, formed from a melted liquid

Porous because the prills contain voids to soak up the diesel fuel.

Amperage or Amps provided by an electrical service is the flow rate of "electrical current" that is available. 

Basic Formulas Relate Voltage, Current (Amps), & Resistance (Ohms or Ω ), Watts

Voltage = Current x Resistance

Current = Voltage / Resistance

Resistance = Voltage / Current

Watts = Volts x Amp

An ammonium nitrate based emulsion, suspension or gel which meets the requirements of UN3375 under the UN (United Nations) classification system.

Offices, workshops, stores, ablutions and the like directly associated with the operation of the ANE premises.

Any designated land, building, or area that is used for the storage, manufacture or handling of ANE. A fence may or may not form, or be part of, the boundary of the premises.

A building, in which an ANE is normally stored and/or handled and where no additional processing of the material into an explosive occurs.

A mixture of ammonium nitrate and fuel oil with or without a dye colouring agent.

The standard mix is 5.8% Fuel Oil by weight.

As diesel has a density of 0.8 this relates to a mix of 7.5 litres of diesel to 100kg of AN.

(Definition from AS2187.0)

A pressure kettle is a device for blow loading ANFO and consists of a pressurised hopper with a valve and venturi on the bottom.

The effective use of a pressure kettle requires the pressure in the hopper and the by-pass pressure to be correctly set.

Typical settings are: By-Pass Pressure 600 KPa, Kettle Pressure 500 KPa

The angle at which the initiation front passes through the blast.

Approval by the regulatory authority having jurisdiction.

AquaMAX is a doped emulsion supplied by Downer Blasting Services

To assess competency under the Blast Management RTO persons must:

1. Hold a Statement of Attainment for the unit of competency that is being assessed or higher. For example a person holding the Shotfirer Units of Competency can assess for RIIBLA201D Support Shotfiring.

2. Hold a Statement of Attainment for ATAESS402B or TAAASS402B/C Assess Competence (or equivalent). Persons holding the qualification TAE40110 or TAA40104 will have completed these units.

3. Have minimum three years relevant industry experience

4.  Complete an 'Approved Assessor Profile' and be signed off as an approved assessor.

Other magazines, process buildings and storages of energetic materials, eg. ammonium nitrate or Class 5 dangerous goods.
