Transport of Explosives on a Public Road
You are a shotfirer responsible for transporting 200 kg of packaged emulsion explosive and 100 detonators from the magazine to a construction site. The journey will take approximately 2 hours on public roads, including a section through a small town. The vehicle is a 3.5-tonne flatbed truck with a wooden bed. The explosives are in their original packaging, and the detonators are in a separate box. The weather is hot (30°C) and dry. You have one assistant. The vehicle is not marked with dangerous goods placards. You have a fire extinguisher and a first aid kit. The site is expecting the delivery by 10 AM. You have a valid explosives certificate and a vehicle authorization document.
1. What are the legal requirements for transporting these explosives by road, and what deficiencies exist in the current arrangement?
Read the worked answer
Transport of explosives by road is governed by legislation such as the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations (CDG) and the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). Key requirements include: proper classification and packaging, vehicle placarding, driver training (ADR certificate), a transport document, and segregation of explosives from detonators. The current arrangement has several deficiencies: the vehicle is not placarded with dangerous goods signs, which is required for quantities above certain thresholds. The detonators and explosives are not properly segregated; they should be in separate compartments or at a safe distance. The vehicle is a flatbed with a wooden bed, which may not be suitable for explosives transport; it should have a non-sparking surface and be covered to protect from weather. The quantity of explosives (200 kg) and detonators (100) likely exceeds the threshold for requiring an ADR-certified driver and vehicle. The driver (shotfirer) may not have ADR training. The transport document is missing. The vehicle should also carry appropriate fire-fighting equipment and be marked. The hot weather may require temperature control for the emulsion. The route through the town may require specific precautions. The shotfirer must ensure compliance before departure.
2. How would you rectify the deficiencies and ensure safe transport?

To rectify the deficiencies, the shotfirer should first check the exact legal thresholds. For ADR, transport of explosives in quantities above 1.1D (or similar) requires full ADR compliance. The shotfirer should arrange for an ADR-certified vehicle and driver. If that is not possible, reduce the quantity to below the threshold or use a licensed explosives carrier. The vehicle must be placarded with orange plates and hazard warning signs. The detonators should be in a separate locked container, ideally in a different part of the vehicle, and secured. The explosives should be in a closed, non-sparking, and weatherproof container. The vehicle should have a fire extinguisher and a spill kit. A transport document detailing the goods, quantity, and emergency contact must be carried. The route should be planned to avoid congested areas where possible. The shotfirer should also consider the temperature; emulsion explosives can degrade in heat, so the load should be shaded and not left in direct sun. The assistant should be trained in emergency procedures. Communication with the site about the delay should be made. Finally, the shotfirer should ensure that all documentation is in order and that the vehicle is inspected before departure.
