A container on a vehicle or at the work site for holding daily requirements of explosives.

Under the AEC a category 2 load for the transport of explosives is up to 5000 detonators and 250 kg of explosives.

The charge carrier is a metal tube with spaced holes to accept perforating charges.

The charge carrier sits inside the gun body after loading. Picture below shows charge carrier being extracted from the gun body.

The area isolated by the nominated shotfirer to manage interaction during the loading of blasts.
This will include all holes to be charged plus a margin.

The charge site is to be demarcated by barriers which can include:

• Physical barriers, rills and windrows
• Visual barriers, signs and flagging tapes
• Communication, notice boards and shift start communications

Standard deviation expressed as a percentage of the mean.

The ground immediately surrounding the opening of a drill hole.

In underground terminology the collar may also refer to the uncharged length of the blast hole as below.

The charging of a drill hole with a continuous charge.

Those groups of explosives which can be stowed or carried together without significantly increasing either the probability of an accident or, for a given quantity, the magnitude of the effects of such an accident. On this criterion, explosives have been divided into a number of compatibility groups, each denoted by a code letter from A to L (excluding I), N and S.

(For further information see the Australian Dangerous Goods Code or the Australian Code for the Transport of Explosives by Road and Rail.)

For commercial blasting explosives the relevant compatibility groups are:

• D - Secondary explosives, may burn may explode
• B - Primary explosives, will explode
• S - Packaging contains the effects of any explosion

Notes:

It is because D (secondary explosives) and B (primary explosives) cannot be stored together (incompatible) that requires separate HE and Detonator magazines.

The Hazard Division is often used with compatibility group. Hazard division refers to the type of explosion hazard that exists. The Hazard Divisions that are relevant to shotfirers are:

• 1 - Mass explosion hazard
• 4 - No significant risk of a mass explosion hazard

Typical codes and examples are shown below:

The authority having jurisdiction for administering legislation covering the manufacture, transport, storage and handling of dangerous goods and / or explosives within a particular State or Territory. There may be more than one authority in an ANE supply chain.

A person who has acquired through training, qualification, experience or a combination of these, the knowledge and skill enabling that person to correctly perform the task.
