Inherent Safety - an approach involving the use of processes and materials with little or no toxicity, flammability or instability - is generally recognized as an important concept in the design of chemical plants. Inspired by the successful development of cleaner production, a feasibility study was conducted for a similar development towards Inherently Safer Production. In four pilot cases carried out in 1997-98, a methodology to generate Inherently Safer technological options was developed and tested. The study indicated that the majority of options had payback times of less than two years, and that Inherently Safer Production was a feasible concept with great potential for simultaneous improvement of safety and economic performance and for integration into cleaner production programmes.
