Your query is not clear to me, but based on my understanding, the FA does not categorize any industry as such. Your login title indicates that you are a safety professional, and you may want to know about the different provisions under the FA specific to safety within industries.
If this is the case, please refer to sections 85 to 91 of the FA under Chapter IX, which deals with Special Provisions. Also, refer to the applicable rules under the same chapter. Upon reading this chapter, one can conclude that the FA categorizes industries/factories into:
- Aid of power industry & non-aid of power industry;
- Public institutions maintained for purposes like education, training, research, or reformation, etc.;
- Industries/factories scheduled based on dangerous operations, hazards, certain diseases, etc.
I am unsure if this is the information you were seeking, or if you had a different query.
Thank you.
