The Center for Chemical Process Safety (CCPS) was founded in 1985 to develop technology and management practices that mitigate or eliminate chemical process accidents. Since that time, CCPS has published more than 100 books and held dozens of international conferences, each representing the most advanced thinking in process safety. CCPS is supported by the contributions and voluntary participation of more than 160 companies globally. CCPS is also the world's largest provider of undergraduate engineering curriculum materials through its SACHE program, with more than 160 universities around the world participating.
