Bulk explosives transport, magazine storage, on-bench charging and primer assembly at Australian mine and quarry sites. Work involves UN Class 1 dangerous goods, licensed magazines and shotfirer-supervised blast crews, triggering SWMS requirements under WHS Regulation 291 (high-risk construction work — explosives) and state mining safety legislation.
Hazards identified
3 hazards covered, sorted by priority.
Fatal blast injuries, multiple fatalities
Unintended detonation, shotfirer fatality
Delayed detonation, crew fatality
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Licensed shotfirer supervises all charging; exclusion zones enforced per AS 2187.2 with radio silence and vehicle lockout.
- 2Use only non-electric (shock tube) initiators near powerlines or RF sources; bond and earth all conductive equipment.
- 3Mandatory 30-minute re-entry delay post-blast; shotfirer clears misfires per AS 2187.2 Section 9 before crew access.
- 4Dual-key magazine access, segregated detonator storage, and quarterly stock reconciliation per state explosives regulations.
Applicable Codes of Practice
Primary code for charging, firing, misfire procedures and exclusion zones.
Mandatory transport, packaging and placarding for UN Class 1 dangerous goods.
High-Risk Construction Work triggered
Direct handling, charging and firing of UN Class 1 explosives at mine and quarry benches.
Charging trucks, MMUs and service vehicles operate alongside crew during loading and stemming.
SWMS mandatory before work starts; PCBU faces Category 1 prosecution if absent.

Worked example
A blasting contractor manages the receipt, storage, on-site transport, and on-bench charging of bulk explosives at an open-cut coal mine in central Queensland, operating a licensed magazine under the Australian Explosives Code and the state explosives regulation. The operation supports a continuous blasting programme under the mine's explosives management plan. The contractor reviews the SWMS against the operation: the magazine licensing and security requirements are confirmed, the separation of detonators from bulk explosive in storage and transport is set, and the static-electricity and ignition controls for charging are established. The dominant hazards are unplanned initiation of explosives, the security of the magazine, and the handling and transport of Class 1 dangerous goods, so the SWMS specifies magazine storage to the licensed conditions with detonators stored separately from bulk explosive, dangerous-goods transport to the explosives code with placarding and segregation, static and ignition-source control during charging, and competency verification for the blast crew. Primers and detonators are assembled at the bench under the charging controls, with detonators kept separate until immediately before use. Stock is reconciled against the magazine records on issue and return so any discrepancy is identified promptly, and the transport between the magazine and the bench follows a planned route under the explosives-vehicle requirements. The magazine, transport, and charging records are documented to the explosives framework, and the operation runs without an unplanned initiation or a security breach, with the licensing and competency records retained under the regulator's requirements.

Frequently asked questions
Why must detonators be stored and transported separately from bulk explosive?
Detonators are sensitive initiating explosives, and storing or transporting them together with bulk explosive means a single ignition or impact event could initiate the whole quantity. The SWMS specifies that detonators are stored in a separate magazine and segregated in transport, and kept separate from the bulk product until immediately before charging. This separation is a fundamental explosives-safety control under the Australian Explosives Code, because it prevents an incident escalating to a mass initiation.
What does the Australian Explosives Code govern for this work?
The Australian Explosives Code governs the transport of explosives as Class 1 dangerous goods — packaging, segregation, placarding, vehicle requirements, and documentation — and informs the storage and handling alongside the state explosives regulation. The SWMS references the code for the transport and segregation controls and the state regulation for magazine licensing. The code and the state regulation together set the framework that the SWMS applies on site.
Why is explosives handling high-risk work?
It involves the storage, transport, and handling of Class 1 explosives with the potential for unplanned initiation, managed under the explosives regulation and the mining safety framework with licensing and competency requirements. An unplanned initiation or a security breach has catastrophic and security consequences. The SWMS treats the work as high-risk and frames the controls around storage separation, transport, ignition control, and crew competency within the operator's explosives management plan.
What magazine security does the SWMS require?
The SWMS specifies that the magazine is operated to its licensed conditions, which include physical security, access control, and stock records, because explosives are a security-controlled material as well as a safety hazard. Detonators and bulk explosive are stored to the licensed configuration with separation maintained. Magazine security is treated as a control on equal footing with the handling controls, because loss or theft of explosives is a serious security risk addressed by the licensing regime.
How does the static-electricity control apply during charging?
Charging bulk explosive, particularly pneumatically loaded product, can generate static electricity that could initiate sensitive components, so the SWMS specifies static and ignition-source control during charging — bonding and earthing where required, and exclusion of ignition sources from the charging area. Static control is a recognised charging hazard for certain products and loading methods. The control is applied during the charging phase alongside the separation of detonators until immediately before use.
