First Interstate Bank Fire
Los Angeles, CA, USA
What Happened
On May 4, 1988, fire gutted four floors of the 62-story First Interstate Bank tower in Los Angeles — at the time the city's tallest building. The building's fire protection was undergoing work: the standpipe system had been drained for maintenance and fire pumps were shut down, so first-arriving crews had no immediate water from the building systems. One person died, about 49 were injured, and damage reached $50 million. The fire is a foundational case for impairment management: NFPA 25 requires formal procedures, notification, and restoration timelines whenever a system is taken out of service.
Preventable with NFPA 14 / 25 Testing
Our analysis classifies this failure as preventable: the deficiency that delayed or defeated fire suppression is the kind that routine inspection, testing, and maintenance under NFPA 25 (and, for standpipe systems, acceptance and periodic testing under NFPA 14) is specifically designed to detect. Equipment failures like this do not announce themselves — they are found by flowing water on a schedule, or they are found during a fire.
Documented Financial Loss & Insurance Outcome
1 death, 49 injuries, $50 million in property damage, 4 floors completely destroyed.
Insurers paid the $50 million building loss claim but initiated subrogation lawsuits against the sprinkler installation contractor and maintenance companies for the deactivated fire protection systems.
About Standpipe Failure Failures(9 in this database)
In any building taller than hose can be stretched from the street, firefighters depend entirely on the standpipe to move water to the fire floor. Cut or disconnected piping, clogged lines, misadjusted pressure-reducing valves, closed valves, and drained systems have all killed firefighters. NFPA 14 governs standpipe design and acceptance testing; NFPA 25 requires periodic inspection and five-year full-flow testing to prove the system still delivers its designed pressure and volume.

Would Your System Pass Today?
This failure was preventable. Routine NFPA 14 & 25 standpipe flow tests and hydrant inspections find failures like this one before a fire does — and keep your insurance coverage intact.
