Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for clear demonstration of PPE use when handling returned explosive articles, as per organisational policy.
- Expect accurate recording of returned goods data in the stock control system, including date, reason, and disposition.
- Credit for correctly identifying non-conforming items and segregating them in a designated quarantine area.
- Look for proper labelling of goods for supplier return, including hazard labels, batch numbers, and required documentation.
- Assess waste disposal actions: verify that waste is segregated, placed in correct containers, and documented promptly.
Assessment Guidance
Guidance for achieving higher grades
- 💡In written assessments, always link your answers to specific sections of the organisational policies and current regulations (e.g., ADR, Explosives Regulations).
- 💡During practical observations, narrate your actions as you perform them to demonstrate underpinning knowledge, especially when checking labels or completing records.
- 💡For scenario-based questions, use the STAR method (Situation, Task, Action, Result) to structure your response, emphasizing the safety and compliance steps taken.
- 💡Always use the correct terminology: 'net explosive quantity' not 'weight', 'compatibility group' not 'type'.
- 💡When answering 'explain' or 'describe' questions, include specific legal references (e.g., ER 2014 Regulation 26) and practical examples.
- 💡For calculation questions, show all working steps and include units (kg) in the final answer.
Common Mistakes
Common errors to avoid in your coursework
- Assuming all returned goods are defective without conducting a proper inspection and documentation review.
- Failing to quarantine returned explosive substances before processing, potentially compromising safety and security.
- Neglecting to update stock control records immediately, leading to inventory discrepancies and audit failures.
- Incorrectly disposing of residual explosive materials—treating them as general waste rather than following special waste protocols.
- Misconception: All explosives can be stored together if they are the same hazard division. Correction: Compatibility groups must also be compatible; e.g., hazard division 1.1 explosives in groups B and C cannot be stored together.
- Misconception: The driver is solely responsible for transport safety. Correction: The consignor, carrier, and driver share responsibilities under ADR (European Agreement concerning the International Carriage of Dangerous Goods by Road).
- Misconception: A risk assessment is a one-time document. Correction: Risk assessments must be reviewed regularly and updated when circumstances change.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A warehouse stores 50 kg of UN 0081 (Explosive, blasting, type A) and 30 kg of UN 0083 (Explosive, blasting, type C). Calculate the total net explosive quantity (NEQ) and state whether they can be stored together, justifying your answer.
- 1.Step 1: Identify the NEQ for each explosive: 50 kg + 30 kg = 80 kg.
- 2.Step 2: Check compatibility: UN 0081 is compatibility group B, UN 0083 is compatibility group C. Groups B and C are not compatible for storage together.
- 3.Step 3: Conclude: They cannot be stored together because they belong to different compatibility groups (B and C) which are not listed as compatible in the ER 2014.
Question: Describe the steps you would take to conduct a risk assessment for transporting 200 kg of explosives by road.
- 1.Step 1: Identify hazards: e.g., fire, impact, theft, unauthorized access.
- 2.Step 2: Determine who might be harmed: driver, public, emergency services.
- 3.Step 3: Evaluate risks: consider likelihood and severity; implement controls such as secure packaging, vehicle marking, and route planning.
- 4.Step 4: Record findings and review: document risk assessment and update as needed.
