They're More Than Just Sprinklers
Faith Fire Protection would suggest the innovations in modern fire suppression for your purposes.
Gaseous Fire Suppression Is Great for Your Industrial Sites
Your gaseous fire suppression system can flood a room with a gas that will quickly exhaust any fire you may experience. It can be risky if your people try to remain inside the room, which is why evacuation is vitally important. Best used for fires where water alone won't do the trick.
Chemical Agent Suppression Could Save You
If you're working with material that could take more than water to put out, and don't want to take the risks surrounding gaseous fire suppression, a chemical agent system could deliver a foam like substance that would take out the fire quickly and efficiently.
