KITCHEN HOOD FIRE SUPPRESSION
TECHNICIAN CERTIFICATION ACTUAL
EXAM 2026/2027 QUESTIONS WITH
VERIFIED ANSWERS & COMPLETE
RATIONALES
**1. What is the primary purpose of a commercial kitchen hood
fire suppression system?**
A. To ventilate cooking odors from the kitchen
B. To regulate cooking temperatures automatically
C. To detect and suppress fires originating from cooking
equipment before they spread
D. To monitor carbon monoxide levels
**Correct answer:** C
**Rationale:** Kitchen hood fire suppression systems are
specifically engineered to detect heat or flames above cooking
appliances and discharge suppressing agents directly onto the
fire, preventing spread and protecting life and property .

**2. Which NFPA standard governs the installation and
maintenance of wet chemical fire extinguishing systems for
commercial cooking operations?**
A. NFPA 13
B. NFPA 17A
C. NFPA 72
D. NFPA 25
**Correct answer:** B
**Rationale:** NFPA 17A specifically addresses wet chemical
extinguishing systems used in commercial cooking operations.
NFPA 96 covers ventilation control and fire protection, while
NFPA 13 covers sprinkler systems and NFPA 72 covers fire
alarm systems .
**3. What type of fire is primarily protected by kitchen hood
suppression systems?**
A. Class A
B. Class B
C. Class C
D. Class K
,3 | Page
**Correct answer:** D
**Rationale:** Class K fires involve cooking media such as
vegetable oils, animal fats, and greases in cooking appliances.
These fires burn at extremely high temperatures and require
specialized wet chemical suppression agents .
**4. What is the primary mechanism by which wet chemical
agents extinguish a grease fire?**
A. Oxygen dilution
B. Saponification
C. Dry chemical interruption of flame chemistry
D. Cooling below autoignition
**Correct answer:** B
**Rationale:** Saponification converts fatty acids into a soapy
foam that traps vapors and cools the fuel surface. This is
unique to wet chemicals and highly effective for kitchen grease
fires .
**5. How often must a kitchen hood fire suppression system be
inspected and serviced?**
, 4 | Page
A. Monthly
B. Every 3 months
C. Every 6 months
D. Annually
**Correct answer:** C
**Rationale:** NFPA 96 and NFPA 17A require that kitchen
hood suppression systems be inspected and serviced at least
every 6 months (semi-annually) by a qualified technician. High-
volume cooking operations may require more frequent
inspections .
**6. What is the function of a fusible link in a kitchen hood
suppression system?**
A. To regulate gas pressure
B. To monitor ambient temperature
C. To automatically actuate the system upon heat detection
D. To connect the suppression tank to the nozzle
**Correct answer:** C
