cold temps


Like I said, it was below freezing for a record time period in B.R. when that happened--like 80-something straight hours of 32-degrees-or-less. Water pipes were freezing up and bursting all over town. I think that record still stands today.

The final investigation on the explosion(s) did take into account the likelihood that the long term subfreezing weather contributed to it in some capacity, as I recall.

Thermal expansion was the cause, regardless of what set the vapor cloud off. The colds temps over night gave way to warn morning/afternoon temps, expansion of the vapor inside...boom.

Huge learning experience about blocking in both sides off a pipeline. The pipeline in question was freezing up (if I remember correctly).

That winter was one of two times I remember the LSU lakes freezing over.
