Hazards & Risks Covered

Hazard Risk Description
1. WHS Governance, Legal Compliance and PCBU Duties
  • • Incomplete understanding of WHS Act 2011 and WHS Regulations as they apply to insulation works (construction, hazardous substances, confined spaces, working at height, plant)
  • • Lack of clearly assigned WHS responsibilities between PCBU, principal contractor, supervisors and subcontractors
  • • Failure to consult, cooperate and coordinate with other duty holders on multi‑PCBU sites (e.g. builders, electricians, HVAC contractors)
  • • No documented WHS management plan for insulation activities on construction projects
  • • Inadequate review of legislative changes, codes of practice and standards relevant to glass wool and batt insulation
  • • Poor records management for risk assessments, inductions, health monitoring, and incident investigations
2. Design, Planning and Integration with Building Services
  • • Inadequate consideration of insulation types (glass wool, batts, sisalation, sound isolation products) during design leading to poor installability or safety
  • • Insulation design that obstructs access to electrical wiring, junction boxes, downlights, skylights or mechanical plant
  • • Failure to plan for safe access/egress into roof spaces and lofts for rafter insulation installation and ceiling panel installation
  • • Insufficient allowance for ventilation requirements, leading to condensation, mould growth and degradation of insulation performance

  • • Lack of supervision for new or young workers undertaking insulation batt installation and loft insulation work
  • • Poor understanding of risk controls for respiratory damage from fibreglass insulation exposure and unsafe handling of glasswool insulation
  • • No system for verifying licences/competencies for plant such as insulation blower machines, EWPs or forklifts used to move insulation
  • • Failure to enforce SWMS implementation on construction sites, leading to drift from agreed controls
5. Induction, Training and Worker Information
  • • Workers unaware of specific hazards associated with glass wool, fibreglass batts, dust, and loft insulation risks
