Impaired Systems Notification & Mitigation

The Seattle Fire Department must be notified of planned or emergency impairments that are anticipated to take a system out of service for more than eight hours. This notification allows the Department to assess the risks and make any operational decisions necessary to ensure response-readiness and the safety of building occupants and firefighters.

Timelines for Notifications

  • Planned Impairments:  At least five business days in advance, with longer notice being preferable.  We recommend that you notify the Seattle Fire Department immediately upon beginning to plan for the impairment.
  • Emergency Impairments:  Immediately.

Mitigation Measures

When a fire protection system is out of order, it may be necessary for you to take mitigation measures to ensure the safety of building occupants and first responders.  An approved fire-watch or other approved mitigation is required for impairment to fire protection systems lasting more than eight hours.
