Fire Risk Appraisal of External Walls - PAS 9980
PAS 9980:2022 gives recommendations and guidance on undertaking a fire risk appraisal of external wall construction and cladding of an existing multistorey, multi-occupied residential building. A fire risk appraisal of external wall construction is described as a Fire Risk Appraisal of External Walls (FRAEW).
The purpose of an FRAEW is to assess the risk to occupants from a fire spreading over or within the external walls of the building and decide whether, in the specific circumstances of the building, remediation or other mitigating measures to address the risk are considered necessary.
The PAS applies where the risk is known, or suspected, to arise from the form of construction used for the external wall build-up, such as the presence of combustible materials or lack of cavity barriers and/or fire stopping. The outcome of an FRAEW is intended to inform the buildings fire risk assessment (FRA).
