What is Inherently Safer Technology (IST)?
IST is a routinely applied safety engineering concept that explores various methods for improving chemical process safety by reducing inventories, replacing chemicals with less toxic substitutes, changing chemical processes, reducing the pressures or temperatures of reactions, etc. The IFR will not prohibit facilities in the chemical sector from considering IST solutions as a form of risk reduction. However, the department also believes that IST is often not appropriate in the security arena, because many IST solutions do not eliminate or reduce risk, but only move risk to another location.
