A clean agent (such as FM-200 or inert gas) suppression system is preferred in which location?
Answer: Data centers and electronic equipment rooms
Clean agents suppress fire without leaving residue or damaging sensitive electronics.
A wet chemical suppression system is specifically designed for which hazard?
Answer: Commercial kitchen cooking equipment
Wet chemical systems saponify cooking oils, making them ideal for kitchen hood and duct protection.
A CO2 total flooding system suppresses fire primarily by doing what?
Answer: Displacing oxygen below combustion levels
CO2 systems reduce oxygen concentration so combustion cannot be sustained.
Why is a CO2 total flooding system a life-safety hazard to occupants?
Answer: It can asphyxiate people by displacing breathable oxygen
Because CO2 displaces oxygen, occupants in the protected space can suffocate, so pre-discharge alarms and delays are required.
A dry chemical extinguishing system commonly protects which area?
Answer: Flammable liquid and industrial hazards
Dry chemical systems interrupt the chemical chain reaction and are used over flammable liquid hazards.
A foam suppression system is most effective against what type of fire?
Answer: Flammable liquid (Class B) fires
Foam blankets flammable liquids, smothering vapor and preventing reignition.
During a fire, what should firefighters confirm about a fixed suppression system before entering a protected space?
Answer: Whether the agent has discharged and the area is safe to enter
Firefighters must know if an oxygen-displacing or toxic agent has discharged to avoid entering an unsafe atmosphere.
