Defective Wiring Causes Fire
Sasha Stone buys a new home entertainment system from Sterling Manufacturing. Weeks later a wiring defect ignites a sudden fire that destroys the system and damages her living room furniture.

Elevator Cable Snaps

Common questions
Frequently Asked
3
What must a plaintiff show to invoke the sudden or dangerous occurrence exception to the economic loss rule?+
The plaintiff must demonstrate that the harm resulted from an event with abrupt onset and substantial hazard that caused personal injury or property damage. Courts then permit recovery of economic losses in tort even when the only harm is to the defective product itself.
Supporting sources
Does gradual deterioration qualify as a sudden or dangerous occurrence?+
No. The exception requires an abrupt event. Slow corrosion or repeated minor leaks over time do not satisfy the suddenness element and therefore do not trigger the exception to the economic loss rule.
Supporting sources
Can a plaintiff recover purely economic loss when a product defect causes only a sudden fire with no personal injury?+
Yes. Property damage from the fire satisfies the exception. The sudden or dangerous occurrence rule focuses on the nature of the event rather than whether personal injury occurred.
