Explosives information bulletin no. 76 | 17 April 2013 | Version 1
The Australian Explosives Industry and Safety Group Incorporated (AEISG) has published the Code of Practice Segregation barriers for transporting mixed loads of detonators and high explosives edition 1 dated June 2012 (AEISG COP Segregation barriers).
The requirements for the transportation of mixed loads of detonators and high explosives are dependent upon the classification of the detonators being transported, i.e. hazard division 1.1 (HD 1.1) or hazard division 1.4 (HD 1.4) and hence when segregation barriers, separate carry boxes and containers are applicable. This bulletin outlines the requirements for the loading of mixed loads of detonators and high explosives on the same vehicle.
The applicable sub-sections of section 7.3.2 of the Australian code for the Transport of explosives by road and rail 3rd edition (AEC3) are included below.
Under sub-section 7.3.2(5) of AEC3, the AEISG COP Segregation Barriers is approved by the Chief Inspector of Explosives as a method for transporting detonators of HD 1.1 with high explosives on the same vehicle.
Features of this approved method include the following:
Detonator boxes and HE containers with Segregation Barriers, without a compliance plate as outlined in the AEISG COP Segregation Barriers, will be accepted until 31 August 2013.
If detonators of HD 1.1 are transported with detonators of HD 1.4, the detonators are all treated as HD 1.1 as outlined in Table 7.1 of AEC3.
For mixed loads involving detonators of HD 1.1 on a body truck or semi-trailer, only detonators can be transported in the detonator box and high explosives can be transported in the HE container. Refer to the diagrams below. (All diagrams reproduced with permission from AEISG.)
For mixed loads involving detonators of HD 1.1 in b double combinations, detonators must be transported in the detonator box. The HE containers may be used for either detonators or high explosive in a mixed load combination. Refer to the table below for the three possible options; and the image below for vehicle combination.
Front – HE container | Middle – detonator box | Rear – HE container |
---|---|---|
High explosives | Detonators H D 1.1 | High explosives |
Detonators HD 1.1 | Detonators H D 1.1 | High explosives |
High explosives | Detonators H D 1.1 | Detonators H D 1.1 |
For mixed loads involving detonators of HD 1.4 being transported with high explosives, there are no restrictions on the loading of detonators and high explosives in any particular compartment or container but they must not be loaded together within the same compartment or container. This applies on body trucks, semi-trailers and b doubles. The requirements of sub-section 7.3.2.(7) of AEC3 apply and hence the requirements of AEISG COP Segregation barriers do not apply.
There are no restrictions on detonators or high explosives being loaded into either the detonator box or HE container.
7.3.2 (3) Unless segregated in accordance with Section 7.3.2(5) or (6) explosives in different Compatibility Groups, regardless of Division, must not be transported together except where permitted by Table 7.2.
7.3.2 (5) Explosives not normally permitted by Section 7.3.2(3) to be transported together, may be transported on the same vehicle provided the incompatible explosives are segregated by:
7.3.2(6) Detonators of Classification Code 1.1B must not be transported on the same vehicle as other explosives except in accordance with an approved method (see Section 7.3.2(5)), or under the following conditions:
7.3.2 (7) Detonators of Classification Code 1.4B or 1.4S may be carried with other explosives on the same vehicle provided they are in a separate carry box or compartment from the other explosives.
