What went wrong in Flixborough disaster?
During the late afternoon on 1 June 1974 a 20 inch bypass system ruptured, which may have been caused by a fire on a nearby 8 inch pipe. This resulted in the escape of a large quantity of cyclohexane. The cyclohexane formed a flammable mixture and subsequently found a source of ignition.

What happened in Seveso disaster?
On July 10, 1976, a valve broke at the Industrie Chimiche Meda Società Azionaria (ICMESA) chemical plant in Meda, just north of Milan, Italy. This accident resulted in the release of a chemical cloud containing the highly toxic dioxin TCDD.
What was nypro?
The Nypro explosion happened because a temporary pipe, on a chemical plant making material to produce nylon, had been fitted to by-pass the space occupied by a large reactor vessel that had been removed for repair.
How can we prevent the Seveso disaster?
This accident could have been prevented. First, with the design of the reactor and ensuring a proper containment system is present in case of an unwanted release. Proper hazard evaluation was not originally completed otherwise the hazards could have been identified and corrected before the release occurred.
