Lesson 2 • History and Industry Context

Traces the development of explosives from black powder to modern compounds. Establishes why historical milestones shape current safety and handling standards.

Lesson 3 • Chemistry of Explosive Reactions

Explains oxidation-reduction reactions, energy release, and gas expansion in detonation. Connects chemical principles to observable blast effects.

Lesson 4 • Physical Properties and Identification

Covers density, detonation velocity, brisance, and deflagration-to-detonation transition. Students can identify materials by measurable physical characteristics.

Lesson 1 • Personal Protective Equipment

Specifies PPE requirements for blasting, storage, and transport tasks. Students select and inspect appropriate equipment for each operational context.

Lesson 2 • Safety Culture in Explosive Operations

Defines safety culture components specific to high-hazard environments. Links individual behaviour to organisational accident prevention outcomes.

Lesson 3 • Risk Assessment and Control Hierarchy

Applies probability-consequence matrices to explosive hazards and maps controls to hierarchy levels. Produces actionable risk registers for field operations.

Lesson 4 • Hazard Identification Methods

Teaches systematic techniques for identifying physical, chemical, and procedural hazards. Prepares students to conduct pre-task hazard reviews on any explosive worksite.

Lesson 1 • Magazine Design and Construction

Covers construction standards, ventilation, grounding, and security requirements for explosive magazines. Students evaluate magazine suitability for specific material types.

Lesson 2 • Theft Prevention and Security Protocols

Addresses physical security, access control, and loss reporting obligations for explosive materials. Students design security plans meeting regulatory requirements.

Lesson 3 • Manual Handling and Transfer Techniques

Teaches safe manual handling, packaging inspection, and transfer procedures for explosive materials. Reduces initiation risk during routine handling tasks.

Lesson 4 • Transportation Regulations and Procedures

Covers vehicle requirements, placarding, route planning, and driver responsibilities for explosive transport. Students plan compliant transport operations end to end.

Lesson 1 • Detonators and Their Types

Compares electric, non-electric, and electronic detonators by function, sensitivity, and application. Builds the selection criteria used in subsequent design chapters.

Lesson 2 • Stray Current and Radio Frequency Hazards

Identifies sources of stray electrical energy and radio frequency interference that can initiate electric detonators. Students apply mitigation measures on active sites.

Lesson 3 • Blasting Machines and Firing Devices

Covers capacitor-discharge and battery-powered blasting machines, testing procedures, and safe firing protocols. Students verify machine output before each use.

Lesson 4 • Initiation Train Assembly

Teaches step-by-step assembly of a complete initiation train from primer to firing device. Emphasises sequence discipline to prevent premature detonation.

Lesson 1 • Rock and Material Properties for Blasting

Covers rock mass characterisation, joint orientation, and material strength parameters used in blast design. Links geotechnical data to explosive selection and loading.

Lesson 2 • Blast Geometry and Pattern Design

Teaches burden, spacing, stemming, and subdrill calculations for bench and surface blasting. Students produce scaled pattern drawings from design inputs.

Lesson 3 • Delay Timing and Sequencing

Explains how delay intervals control fragmentation, vibration, and flyrock. Students assign delay sequences to achieve target outcomes.

Lesson 4 • Explosive Selection and Loading

Matches explosive products to hole conditions, water presence, and fragmentation requirements. Students calculate powder factor and charge weight per hole.

Lesson 1 • Firing and Blast Execution

Covers final connection, all-clear signalling, firing command protocol, and observer positioning. Students execute a simulated blast sequence with full procedural compliance.

Lesson 2 • Pre-Blast Site Preparation

Covers exclusion zone establishment, utility clearance, and equipment positioning before loading begins. Prevents third-party exposure and equipment damage.

Lesson 3 • Drilling and Hole Preparation

Addresses drill pattern layout, hole deviation measurement, and hole conditioning before loading. Ensures holes conform to the approved blast design.

Lesson 4 • Loading and Stemming Procedures

Teaches sequential loading of primers, explosives, and stemming material with anti-static precautions. Maintains charge integrity and prevents bridging.

Lesson 1 • Unplanned Detonation Response

Covers immediate actions, casualty management, and site security following an accidental detonation. Integrates emergency response plans from the safety chapter.

Lesson 2 • Incident Investigation Techniques

Applies root-cause analysis methods including fault tree and fishbone diagrams to explosive incidents. Produces findings that drive corrective action plans.

Lesson 3 • Reporting and Regulatory Notification

Defines mandatory reporting timelines, content requirements, and agency notification procedures for explosive incidents. Students draft compliant incident reports.

Lesson 4 • Misfire Causes and Prevention

Analyses electrical, mechanical, and procedural causes of misfires and links each to preventive controls. Builds diagnostic thinking applied in later resolution sections.

Lesson 1 • Specialised Blasting Applications

Covers controlled demolition, underwater blasting, and tunnel perimeter blasting techniques. Students adapt standard design principles to constrained environments.

Lesson 2 • Airblast and Flyrock Management

Quantifies airblast overpressure sources and flyrock trajectory factors, then applies design controls. Students redesign problem blasts to meet overpressure limits.

Lesson 3 • Blast Performance Monitoring and Review

Establishes key performance indicators, fragmentation measurement methods, and design feedback loops. Students use monitoring data to iteratively improve blast designs.

Lesson 4 • Vibration Prediction and Control

Uses scaled-distance equations and site-specific attenuation data to predict and limit ground vibration. Students calculate maximum instantaneous charge for compliance targets.
