Which type of fire suppression system is most appropriate for protecting a room storing water-reactive chemicals?
Answer: Carbon dioxide (CO2) total flooding system
CO2 total flooding systems use an inert gas that does not react with water-reactive chemicals, making them appropriate for such environments.
What does the 'T' in TRACEM stand for in hazardous materials incident size-up?
