You need to refer the Chapter on Safety in the Gujarat Factories Rules, and the rule on fire fighting apparatus and water supply.
I have not read Gujarat Factories Rules. But according to Maharashtra Rule, you should make adequate provision of water supply fire fighting. The rules have further provision for power-driven trailer pumps of adequate capacity on certain parameters such as total area in square metres of all floors including galleries in all buildings of the factory, total area in square metres of all floors and galleries including open spaces in which combustible materials are handled or stored, total area in square metres of all floors over certain meter above ground level, total area in square meters of all floors of buildings other than those of fire-resisting construction provided fire-resisting constructions of various floors is so certified by any Fire Association or Fire Insurance Company,etc.
Each trailer pump shall be provided with equipment as per Schedule thereto. Such equipment shall conform to Indian Standard specifications whenever they exist.
If the Chief Inspector is satisfied in respect of any factory or any part of the factory that owing to the exceptional circumstances such as inadequacy of water supply or for infrequency of the manufacturing process or for any other reason, to be recorded in writing all or any of the requirements of the rules are impracticable or not necessary for the protection of workers he may by order in writing (which he may at his discretion revoke) exempt such factory or part of that factory from all or any of the provisions of the rules.
I am sure, Gujarat Rules are more or less similar to above.
You also need to take NOC from your fire department. This NOC is given on various parameters.
All this things are technical in nature which needs expertise in subject. Your factory plans are not approved unless you full all the requirements. The architect you hire for plans layout takes care of everything.
