Study Notes
Inherent Safety in Chemical Processes
- The main focus of Inherent Safety in chemical processes is to minimize hazards and risks.
- ISD stands for Inherently Safer Design.
Inherently Safer Design (ISD)
- ISD is more of a philosophy than a specific set of tools or methods.
- According to T.A. Kletz, the essence of Inherently Safer Design is to design a process to be safe without the need for add-on safety features.
- ISD was first developed as an important tool for process safety management in the 1970s.
Safeguards in Chemical Processes
- The primary purpose of safeguards in chemical processes is to prevent or mitigate accidents.
- Decision-making in ISD must consider the entire lifecycle of the process.
Safety Incidents
- The "Swiss Cheese" model is mentioned in the text for safety incidents.
Managing Chemical Process Safety
- Strategies for managing chemical process safety include Inherently Safer Design, Passive Safety, Active Safety, and Procedural Safety.
- When an option is safer concerning some hazards but less safe concerning others, trade-offs must be made.
Inherent Safer Design Principles
- ISD stands for Inherently Safer Design in the context of the text.
- The "Simplify" principle in Inherent Safer Design aims to reduce the number of components and reduce complexity.
- Lower operating pressures in ammonia plants contribute to safety by reducing the potential energy released in an accident.
- The "Moderate" principle in Inherent Safer Design aims to minimize the intensity of the process.
Publication and Incidents
- Kletz's publication "Inherently Safer Plants" discusses Inherently Safer Design.
- The original design for cooling tower water treatment used chlorine.
- The Bhopal, India incident involved a chemical plant owned by Union Carbide.
- Methyl isocyanate was used as an intermediate in the Bhopal plant.
- The financial situation of the Bhopal plant was poor according to the text.
- Local officials allowed the growth of a shanty town near the plant.
Design Principle
- The design principle promoted in the lecture notes is Inherently Safer Design.
- "In situ" manufacture can address the challenges related to hazardous materials.
