2. Explosives Procurement, Transport & Chain of Custody
  • • Procurement of incorrect explosive type, detonators or accessories for the intended blasting work
  • • Supply from vendors that do not comply with Australian explosives manufacture and transport regulations
  • • Loss, theft or diversion of explosives or detonators due to weak chain-of-custody systems
  • • Inadequate security during road transport and site delivery of explosives and detonators
  • • Poor segregation of detonators and bulk explosives during transport, increasing risk of inadvertent initiation
  • • Failure to verify quantities received, resulting in unaccounted explosives after blasting activities
3. Explosives Storage Facilities & Inventory Control
  • • Inadequate design, construction or siting of magazines for storage of explosives or detonators
  • • Insufficient separation distances from public areas, occupied buildings, fuel stores or infrastructure
  • • Poor stock rotation leading to degradation, misfires or instability of explosives
  • • Unsecured magazines allowing unauthorised access, pilferage or deliberate misuse

4. Organisational Structure, Roles & Responsibilities for Blasting
  • • Unclear allocation of responsibilities between PCBU, mine or quarry manager, blasting contractor and subcontractors
  • • No formally appointed, competent shotfirer or blasting engineer with authority over explosives safety decisions
  • • Conflicting instructions from production and safety leadership resulting in unsafe compromises on blast design or exclusion zones
  • • Inadequate supervision of blasting operations, particularly for new crews or non-routine blasting (e.g. stump removal near utilities)

5. Competency, Training & Authorisation for Explosives Work
  • • Use of explosives by personnel without required licences, tickets or verified competencies
  • • Insufficient training in explosives-specific WHS procedures, leading to unsafe practices
  • • Inadequate understanding of blast design principles, leading to miscalculation of charge weights or delays
  • • Lack of training in controlled blasting near structures, services or sensitive environments
  • • Poor familiarisation with specific initiation systems, electronic detonators or remote firing systems
  • • Failure to provide refresher training, causing skill fade for infrequently performed tasks such as stump removal blasting
6. Blast Design, Planning & Engineering Review
  • • Inadequate blast design for geological conditions, leading to flyrock, excessive vibration or loss of control
  • • Failure to account for nearby infrastructure, underground services, buildings or public areas in blast design
  • • Inappropriate explosive type, charge weight or delay timing for controlled blasting objectives
  • • Insufficient engineering review of rock blasting patterns, stemming and burden, increasing risk of misfires or uncontrolled rock movement
