This Transformer in a Unit Substation exploded and burned for more than three hours. The Fire Department had to spray water on the adjacent buildings during the fire to keep them from burning to the ground. SPI Petro-Barriers™
are used in this substation for oil containment. After the fire was extinguished and a new transformer was installed, SPI was called in to examine the HDPE Sumps that are used to house the Petro-Barriers™.
The HDPE Housing melted down about 1/2” from the top but was otherwise intact. The used Petro-Barrier Media was
vacuumed out of each sump where the Transformer Oil had spilled and affected the SPI Media about 10" down into the
unit. Notice how the concrete floor is all broken up from the Intense Heat, but the SPI Petro-Barrier™
Sumps were intact
and still provided 100% Spill Protection. New media was installed in the SPI Petro-Barrier™
and the crumbled
concrete was removed and replaced at a later date.
