When things go wrong – Parkinsons law in emergencies

A hydrocarbon spill occurred in a plant and caught fire. Sulphuric acid pipelines nearby leaked and were dumping suplhuric acid into the hydrocarbon spill. The sulphuric acid was breaking down the fire fighting foam used by firefighters and delayed the extinguishing of the fire.
In my experience of handling many emergencies, things will go wrong during an emergency. The better prepared you are, the better you are equipped to handle surprises.
