Impairment Management
Impairment management is the cross-system governance of planned and unplanned outages of protection, detection and security systems – from suppression systems through fire alarms to security equipment – aimed at minimising downtime and compensating the loss of protection while a system is out of service.
Why generalise
Sprinkler systems are not the only systems that go out of service: fire alarm panels, gaseous suppression systems, intrusion detection, back-up power and safety-critical process equipment are impaired just as often for maintenance, alteration or fault repair. The core principles of impairment governance – categorisation, authorisation, compensation, restoration – apply regardless of the system affected and build on the established procedures for sprinkler systems.
Core elements
A distinction is made between planned, unplanned (emergency) and hidden impairments. A central authorisation and tagging system records every impairment with duration, cause and the responsible person; before work starts, plant security, the fire brigade, the alarm receiving centre and the property insurer are notified. Compensating measures such as fire watches, temporary notification arrangements or additional patrols bridge the protection gap until the system has been verifiably restored.
Insurance relevance
Property insurers increasingly require notification of longer impairments regardless of the system type affected and treat unannounced or hidden outages as a material deterioration of the risk. A cross-system impairment register improves the risk assessment and avoids coverage disputes after a loss.
