This record contains Part D of the Protocols for Mitigating Cladding Risk (PMCR): the Support Packages developed by Cladding Safety Victoria (CSV) as part of Victoria’s risk-based framework for addressing combustible cladding risk on relevant Class 2 and Class 3 buildings. Part D comprises: D.01 – Cladding and Materials D.02 – External Fire Threats to Cladding D.03 – Balcony Fires D.04 – Risk Benefits D.05 – Sprinkler Protection These documents capture the technical, scientific and risk-based evidence used to support and calibrate PMCR application. They examine key issues relevant to combustible cladding risk, including material fire performance, external ignition threats, balcony fire scenarios, risk reduction benefits and the role of sprinkler protection. Part D supports the broader PMCR document set by providing the evidence base for the assessment, policy and intervention approach, including: Part A – Authorisation, which codifies the Victorian Government decisions that enable PMCR activation; Part B – CRPM Methodology, which specifies the Cladding Risk Prioritisation Model used to assess cladding risk and assign buildings to risk levels; Part C – PMCR Foundation, which defines the PMCR method, objectives and key design tasks; Part E – CSV Cladding Risk Policy, which establishes key CSV policy positions in relation to cladding risk; Part F – PMCR Interventions, which identifies the interventions that may be used to mitigate combustible cladding risk; and Part G – Implementation, which specifies the standards and procedures that guide PMCR application. CSV’s cladding fire testing program also forms part of the broader technical evidence base informing the PMCR. The test reports provide practical evidence of cladding and wall-system fire behaviour under defined conditions, supporting a risk-based approach grounded in observed fire performance. Separately published peer review material and CSV responses provide additional assurance for the PMCR methodology. These reviews considered the methodology, reasoning, risk approach and proposed interventions, with CSV responses showing how feedback was considered in refining the document set. This supports transparency and provides further confidence in the technical basis and practical application of the PMCR. In particular, Part D informs PMCR decision-making through analysis of ACP, EPS, cladding material behaviour, external fire exposure, vehicle and waste bin fires, balcony ignition risks, fire spread modelling, risk-benefit assessment, Bayesian network modelling, and sprinkler protection. The documents should be read as technical support documents within the PMCR framework. They should not be read as standalone building assessments, compliance determinations, remediation approvals or universal risk ratings for any individual building. Rather, they provide the supporting evidence and analysis used to inform Victoria’s broader combustible cladding risk mitigation program.
