Impairment
A condition where a fire protection system is partially or fully out of service and unable to perform its intended function.
In Detail
An impairment is any condition that renders a fire protection system partially or fully unable to perform its intended function. Impairments can be planned (system shutdown for maintenance, construction, or modification) or unplanned (equipment failure, water supply interruption, power outage). NFPA 25 requires a formal impairment handling procedure including: notification to the building owner, insurance carrier, and AHJ; implementation of alternative protection measures (fire watch, temporary connections); tagging of impaired equipment; setting a target restoration date; and documenting the entire process. The impairment coordinator (typically the building owner's representative) is responsible for ensuring these steps are followed. Failure to manage impairments properly creates significant liability — if a fire occurs during an undocumented impairment, insurance coverage may be affected.
