Reduce risk by applying inherently safer principles

3 Reduce risk by applying inherently safer principles 

The basic concept of inherently safer process design is to reduce the hazard of a process by reducing or eiiminating the hazards associated with materials and operation of the process. This approach is described in detaii in the CCPS book, Inherently Safer Chemical Processes, A Lifecycle Approach, 2nd edition, 2008. in brief, there are four major strategies for inherently safer design  

Minimize - Use smaiier amounts of hazardous substances (also called Intensification). 

Substitute - Repiace the material with a less hazardous material. 

Moderate - Use iess hazardous conditions, a less hazardous form of a material, or facilities that minimize the impact of a reiease of hazardous material or energy (also called Attenuation and Limitation of Effects).
