===Safety and hazard developments===
Concerns regarding large-scale chemical manufacturing facilities' safety and environmental impact were also raised during this period. ''[[Silent Spring]]'', published in 1962, alerted its readers to the harmful effects of [[DDT]], a potent [[insecticide]].<ref>{{Cite journal |last=Dunn |first=Rob |date=May 31, 2012 |title=In retrospect: Silent Spring |journal=Nature |language=en |volume=485 |issue=7400 |pages=578–579 |doi=10.1038/485578a |bibcode=2012Natur.485..578D |s2cid=4429741 |issn=0028-0836|doi-access=free }}</ref> The 1974 [[Flixborough disaster]] in the United Kingdom resulted in 28 deaths, as well as damage to a [[chemical plant]] and three nearby villages.<ref>{{Cite journal |last=Bennet |first=Simon |date=September 1, 1999 |title=Disasters as Heuristics?

By the 1970s, legislation and monitoring agencies were instituted in various countries, such as France, Germany, and the United States.{{sfn|Perkins|2003|p=35}} In time, the systematic application of safety principles to chemical and other [[Process manufacturing|process plants]] began to be considered a specific discipline, known as [[process safety]].<ref>{{Cite book |last=CCPS |title=Introduction to Process Safety for Undergraduates and Engineers |publisher=[[John Wiley & Sons]] |year=2016 |isbn=978-1-118-94950-4 |location=Hoboken, N.J.}}</ref>
