There are clauses in the Maharashtra Factories Rules, 1963 regarding the storage of paints, specifically concerning lightning protection and fire protection. Please refer to the state factory rules for more details.
Apart from that, please check whether the paints fall under the permissible limits of safe storage as per The Petroleum Act & Rules. Verify with the MSDS of each paint you intend to use to classify it under Class A, Class B, or Class C, and adhere to the specific storage and usage requirements outlined in The Petroleum Act & Rules.
Once you have reviewed both of the aforementioned legislations, if you still need any further clarifications, please feel free to come back to the forum.
