Hello Everyone,

I am Nitin Jadhav, a Chemical Engineer working in Process Safety and Loss Prevention since July 2015.

I currently work as an Assistant Design HSE Manager at one of the world’s leading EPC companies.

This is my personal website, where I will write about what I do, share my experiences, and keep all my notes and learnings in one place.

I hope you will enjoy and, at the same time, learn about Process Safety and Loss Prevention.

Process Safety and Loss Prevention is a relatively small field, with a limited number of engineers working in it. However, it is one of the most important and crucial disciplines in design engineering.

Through this website, I will share my knowledge, experience, notes, and learnings, with the hope that they will be useful to everyone interested in Process Safety and Loss Prevention.

A Website Structured Like a Book

This website is structured like a book. The complete list of chapters is provided below, and each chapter is further divided into dedicated sub-chapters, presented as individual articles.

I originally wanted to write a dedicated book on Process Safety and Loss Prevention. However, a traditional book cannot be continuously updated as new knowledge, practices, standards, and learnings evolve.

Therefore, I decided to create this website instead — a living book that can be continuously updated, improved, and expanded over time.

More Than Just a Blog

I also want to highlight that this is not just my blog. I would like this website to become a Process Safety and Loss Prevention Forum.

You are welcome to comment, share your suggestions, point out corrections, contribute your knowledge, and suggest improvements to the content.

The objective is not only to share what I know, but also to learn from others and collectively improve the knowledge and understanding of Process Safety and Loss Prevention.

I hope you will enjoy the journey and, at the same time, learn something new along the way.

Welcome to the Process Safety and Loss Prevention Forum.
