If you want to be a Safety Manager sometime laterwards in your career, then the knowledge from the course of BTech Fire and Safety Engineering can be really helpful. As you will know the technical perspective of the safety, you would be more efficient compared to others who won't have this knowledge.

If you want to have an accelerated career in the profile of Safety Management, then after completion of Engineering you should pursue the course of MBA in Safety Management in order to have better career ahead.

I hope my answer provides you some insight. Wish you a great day!
