Fire dampers play a critical role in maintaining compartmentation by preventing the spread of fire and smoke through ventilation and air-conditioning systems. However, surveys across many healthcare, commercial and residential buildings frequently identify fire dampers that are missing, inaccessible, incorrectly installed, damaged, or inadequately maintained. Effective remediation requires a structured, risk-based approach to ensure that limited resources are directed towards the areas of greatest life safety benefit.
The first priority should be dampers located within fire-resisting walls and floors that form part of the building's primary fire strategy. These may include compartment walls, sub-compartment walls, protected escape routes, critical shafts, and areas supporting progressive horizontal evacuation. Defects in these locations can undermine the overall compartmentation strategy and significantly increase the risk of fire and smoke spread. Similar concerns have been identified in healthcare fire safety reviews, where passive fire protection defects were recognised as having the potential to compromise evacuation strategies.
The second priority should focus on high-risk occupancy areas. In healthcare premises, this includes theatres, intensive care units, wards, and areas housing vulnerable occupants who may not be able to self-evacuate. In other building types, sleeping accommodation, care homes, and places of assembly should receive similar attention.
The third priority is accessibility and maintainability. Dampers that cannot be inspected, tested, or reset present an ongoing compliance and safety risk. Remediation works should therefore include the provision of suitable access hatches and accurate asset records.
A robust remediation programme should also consider the condition of associated systems, including fire-stopping around duct penetrations, damper identification labelling, and maintenance documentation. Each defect should be risk-rated, recorded, and tracked through to completion.
Where there is a large building sized problem with dampers, combined with limited budgets, then this table can be used. This considers the location of the damper together with the possible modes of failure to stop smoke and fire. By combing these two factors, each location can be scored, with a total score of 25 which would equate to the highest priority for remediation. For instance, a score of, say, 15 or above would qualify for the initial phase of works. Try it.....
