The US Chemical Safety Board (USCSB) recently released a video describing the refinery explosion in Philadelphia in 2019, primarily showing the hazard that is HF.
Watch the video here.
It gives details of the sequence of events, and points out that the safeguards to prevent an HF release they had in place DID NOT FUNCTION.
The video also names five recommendations to make all the HF-using refineries safer. Note that number 5 is “Inherently Safer Design” – replacing HF with another alkylation process.
We strongly recommend that you view this important video.
