A hydraulic oil storage tank caught fire, which shut down a power plant. The root cause of the fire was attributed to collapse of an 8-inch stainless steel float ball used as a level indicator inside the hydraulic oil tank.

Using mechanical stability analysis and thermodynamics, it was shown that the float ball collapse and the fire were coincidental.
