Which type of extinguishing system is installed in areas with computers or sensitive electronics?

• A. Foam
• B. Water spray
• C. Gaseous system
• D. Dry chemical

Answer: (C)

In rooms with computers or sensitive electronics, you want an extinguishing method that won’t damage or short out equipment. A gaseous extinguishing system does exactly that by releasing a clean agent into the space to interrupt the flame chemistry or displace heat and oxygen without soaking the gear. This minimizes residue and moisture, which protects electrical components and reduces cleanup. Foam or water spray would bring water and potential short circuits, while dry chemical leaves corrosive residue and can foul electronics. Therefore, a gaseous system is the best fit for protecting sensitive electronic equipment.
