Q1.
Which component automatically detects a fire in the kitchen hood duct and
releases the suppression agent?
• A) Manual pull station
• B) Fusible link
• C) Heat detector (rate-of-rise)
• D) Smoke detector
Correct Answer: B
Verification: Verified against NFPA 17A 2025 edition, Section 7.3.
Rationale: Fusible links are mechanical devices that melt at a specific
temperature (typically 212°F–360°F for hood systems), releasing tension on
the mechanical release mechanism. Rate-of-rise heat detectors (C) are used
in building fire alarms, not pre-engineered wet chemical systems. Smoke
detectors are ineffective due to cooking effluents.
Q2.
What color is the wet chemical suppression agent typically stored in the
cylinders for restaurant systems?
• A) Red liquid
• B) Clear water-based solution
• C) Amber/light brown liquid
• D) Purple powder
,Correct Answer: C
Verification: Manufacturer data sheets (Ansul, Kidde, Buckeye) 2026.
Rationale: Wet chemical agents (potassium acetate, potassium citrate, or
blended formulations) are typically amber/light brown. Purple powder (D) is
dry chemical (Purple K) used in other fire classes but not in commercial
kitchen wet systems due to dispersal and cleanup issues.
Topic 2: Installation & Placement
Q3.
According to NFPA 96, what is the maximum distance allowed between a
fusible link and the edge of a cooking appliance’s grease-producing area?
• A) 6 inches
• B) 12 inches
• C) 18 inches
• D) 24 inches
Correct Answer: B (12 inches)
Verification: NFPA 96 2025, Section 10.5.3.
Rationale: Links must be within 12 inches horizontally and vertically from
the grease-laden vapors’ expected flame plume to ensure rapid activation.
18 or 24 inches would delay activation, allowing fire growth.
Q4.
Nozzles installed inside the exhaust duct must be positioned to discharge
agent:
• A) Upward into the fan
• B) Horizontally across the duct’s centerline
, • C) Downward toward the baffle filters
• D) Toward the duct access panel
Correct Answer: B
Verification: NFPA 17A, Section 9.2.4.
Rationale: Discharge across the duct’s centerline ensures wet chemical coats
both the duct walls and the air stream, extinguishing flame traveling
upstream/downstream. Upward (A) would blow agent out the fan;
downward (C) only wets bottom surface.
Topic 3: Inspection & Maintenance
Q5.
How often must a certified technician perform a semi-annual inspection on a
wet chemical kitchen hood system?
• A) Monthly
• B) Every 3 months
• C) Every 6 months
• D) Annually
Correct Answer: C
Verification: NFPA 17A 2025, Table 11.2.1.
Rationale: NFPA 17A requires semi-annual inspections (every 6 months) by a
trained/certified technician. Monthly (A) is for visual checks by the owner;
annual (D) is insufficient.
Q6.
During a 6-month inspection, you find a nozzle orifice clogged with grease.
What action is required?
