Fire Fighting System Design (Newbie)
(OP)
Ok, so I have a layout/floor plan of a small power plant. I've already determine the Classes of Fire on each room. I should only have Class A and Class B fire.
Now, since water is not recommended for class C, (fire originates from energized electrical equipment, particularly, household appliances, computers, or overheard transmission lines). Recommended is Dry powder. Should I put only a Dry powder extinguisher? How about the materials from class A? Should I put water fire fighting system?
This room is a control room, it has materials from class C (fire originates from energized electrical equipment, particularly, household appliances, computers, or overheard transmission lines) and materials from class A ( fire involves ordinary combustibles such as paper, wood, cloth and plastics. Use fire extinguishers with water). Should it require Dry powder only? Or both Dry Powder and Water?
If both dry powder and water is required, my plan is to put a portable dry powder extinguisher inside the control room and include the control room to my water sprinkler system design. (Is this right? both in rules and economics?)
Thanks!

There are suppression systems that use Halon, Halotron and water mist. Obviously, more expensive than portable extinguishers. Also, suppression systems trip a fire alarm, which adds to the expense. The alarm system can also shut down air systems, mechanical equipment, and electrical power. Companies that sell clean agent systems include Amerex, Ansul, 3M, and Solberg. Clean agent systems may require a vapor tight room. Even with a suppression system, you will need portable extinguishers.
Start with NFPA's on-line Buyer's Guide for companies that sell the different options. They can help you make a choice.
