I found that your query is how many members have to be trained in fire fighting .
Ans: Ten percent (10%) of the workers must be trained.
It is clearly explained in Andhra pradesh Factories Rules 1950 .
Schedule No 15- Chemical Works , Part-II General requirements Point no 9 in Rule no 23: Procedure for meeting emergencies ( Page no 509 last sentence 9th point in 14th edition of Factories act and Andhra pradesh Factories rules 1950)
The Occupier shall arrange to have ten percent of the workers trained in the use of First aid, Fire Fighting appliances.
Please give basic training to all the employees in your organisation about how to handle the Fire Extinguishers and simple First Aid Cases.
You can give advanced training in Fire Fighting to some specified employees (2 persons in each department), so that in case of any emergency they can handle effectively without much loss to property and life.
