I have seen many places are adopting the practice of using the high-expansion foam for their impounding pond which take the spill of LPG from the sphere tank.
As I go through NFPA 11, it states as below quoted;
As per my understanding, there is a risk from vapor cloud formation under foam blanket and reignition.
Hence I still not sure whether, using of water spray to disperse the spill liquid or using high-expansion foam, which one is the best fire fighting strategy.
Please advise or share your experience.
