Abrasive Blasting Risk Assessment

Product Overview

Identify and control organisational risks associated with Abrasive Blasting through a structured, management-level Risk Assessment that focuses on governance, planning, plant, and systems of work rather than task-by-task procedures. This document supports executive Due Diligence, aligns with the WHS Act, and helps protect your business from regulatory breaches and operational liability.

Risk Categories & Hazards Covered

This document assesses risks and outlines management controls for:

  • WHS Governance, Duties and Regulatory Compliance: Assessment of officer due diligence, PCBU obligations, consultation arrangements, and integration of abrasive blasting risks into the broader WHS management system.
  • Planning, Design and Layout of Abrasive Blasting Facilities: Management of facility design, segregation of blasting areas, traffic and pedestrian interfaces, access/egress, and controls for overspray, drift and environmental impact.
  • Plant, Equipment and Procurement Management: Controls for selection, specification and lifecycle management of blasting plant, compressors, hoses, nozzles, enclosures, guarding and engineering controls, including procurement and verification of compliance.
  • Hazardous Substances, Dust, Silica and Fume Management: Assessment of exposure risks from abrasive media, coatings, lead, silica and other hazardous substances, including SDS management, substitution, isolation and engineered dust control strategies.
  • Noise and Vibration Risk Management: Management of high-noise and vibration exposures from blasting operations, including noise surveys, engineering controls, administrative controls, and hearing conservation programs.
  • Ventilation, Atmospheric and Confined Space Controls: Protocols for ventilation design, negative pressure blasting rooms, atmospheric monitoring, and integration with confined space entry controls where applicable.
  • Maintenance, Inspection and Integrity of Plant and Infrastructure: Systems for inspection, testing, tagging and preventative maintenance of blasting equipment, pressure systems, structures, enclosures and extraction systems to prevent catastrophic failures.
  • Safe Systems of Work, Procedures and Permit-to-Work: Development and governance of documented procedures, isolation/lockout processes, hot work and confined space permits, and coordination of simultaneous operations.
  • Training, Competency and Supervision: Requirements for competency-based training, verification of skills, induction programs, supervision levels and refresher training for abrasive blasting personnel and support staff.
  • Personal Protective Equipment and Respiratory Protection Program: Management of PPE selection, fit testing, respiratory protection programs, maintenance, storage and replacement of blasting suits, helmets, hearing and eye protection.
  • Health Surveillance, Medical Monitoring and Fitness for Work: Systems for health monitoring related to silica, lead, solvents and noise, along with fitness for work, fatigue, and substance impairment controls.
  • Contractor, Client and Supply Chain Management: Governance of contractor selection, pre-qualification, information exchange with clients, and management of suppliers of plant, abrasives and coatings to ensure WHS standards are maintained.
  • Emergency Preparedness and Response: Planning for fire, explosion, loss of containment, medical emergencies, and rescue from confined or difficult-to-access blasting areas, including drills and communication protocols.
  • Monitoring, Auditing and Continuous Improvement: Establishment of KPIs, inspections, audits, incident reporting, corrective actions and management review processes to drive ongoing improvement in abrasive blasting risk controls.

  • • Lack of documented WHS policy covering all abrasive blasting operations (cabinets, open blasting, shot peening, pipelines, boats, architectural components, vehicle smash repairs, industrial manufacturing, mechanical engineering templates, diesel mechanic work, signwriting and shopfitting)
  • • Poor change management when introducing new blasting media, machinery (sandblasters, shot blasting machines, glass bead units, grit blasting systems) or new work environments (boat yards, pipelines, confined spaces)
  • • Inadequate consultation with workers and Health and Safety Representatives (HSRs) on blasting‑related risks and controls
  • • Insufficient integration of contractor management for external abrasive blasting specialists or hire equipment providers
  • • Lack of formal WHS objectives, performance indicators and review processes specific to abrasive blasting exposures (silica, dust, noise, vibration, high‑pressure energy)
2. Planning, Design and Layout of Abrasive Blasting Facilities
  • • Poor facility layout leading to worker exposure to dust, noise and rebound media from blasting cabinets, blast rooms and open‑air blasting areas
  • • Inadequate separation of abrasive blasting from other trades (diesel mechanics, smash repairs, signwriters, shopfitters, mechanical engineering, boat building) causing cross‑contamination of dust and noise

  • • Inadequate segregation of noisy blasting operations (grit blasting, shot blasting, glass bead blasting) from quiet workspaces and offices
  • • Poor planning of blasting in shared environments such as marinas, dry docks, pipelines and construction sites resulting in uncontrolled drift of dust and spent media to public areas
  • • Lack of engineered containment when prepping surfaces on architectural windows and doors, vehicles, boats or large structures, relying solely on PPE
  • • Insufficient consideration of access, egress and emergency routes within and around blast rooms, cabinets and temporary blasting enclosures
  • • Inadequate structural design and rating of booths, cabinets and enclosures for negative pressure, explosion risk and media rebound
3. Plant, Equipment and Procurement Management
  • • Procurement of abrasive blasting equipment (sandblasters, shot blasting machines, sandblasting cabinets, glass bead systems, portable pots, compressors) without WHS specification or compliance checks
  • • Use of plant lacking appropriate guarding, interlocks, pressure relief devices or explosion protection for blast pots and dust collectors
  • • Incompatible or unsafe blasting media (e.g. high‑silica sand) leading to excessive respirable crystalline silica exposure
  • • Poorly specified or undersized compressors, hoses and fittings leading to hose whip, sudden failure or uncontrolled high‑pressure release
  • • Lack of design verification and records for pressure vessels and piping used in grit blasting and shot blasting systems
  • • Inadequate procurement controls for hire equipment or contractor‑supplied blasting units with unknown maintenance histories
  • • Failure to standardise on quality‑assured respiratory protection and blasting helmets across operations and sites
