Failing of two switchboards a credible scenario?

Failing of two switchboards a credible scenario?

Failing of two switchboards a credible scenario?

(OP)
For checking of a flare header, we have to decide which partial power failures can be disregarded as uncredible.
The electrical system of the refinery consists of two main substations, located in two separate buildings. Each substation consists of two switchboards, each distributing the power to different parts of the refinery.
Question is what the possibility is that two switchboards in a single substation fail simultaneously. Does anyone have figures, or know where to find figures in relation to damage (e.g. car crash, lightning), or if one board fails the other board will be damaged as well.
Also more qualitative considerations (e.g. experiences in your own plant/refinery) are wellcome!
