EXAM QUESTIONS
Question 1 – Flash Point of Adhesive Coatings
Liquid adhesive coatings used on air filters for air conditioning or heating systems shall have a
flash point not lower than:
,Page 2 of 63
A) 200°F
B) 250°F
C) 350°F
D) 325°F
Correct Answer:
D) 325°F
Rationale:
IMC Code 605.1 requires that adhesives on air filters must have a flash point not lower than
325°F to reduce fire hazards.
Question 2 – Chimney Flue Connectors
Connectors shall connect to a chimney flue at a point not less than ______ above the lowest
portion of the interior of the chimney flue:
A) 10 inches
B) 12 inches
C) 16 inches
D) 14 inches
Correct Answer:

,Page 3 of 63
Rationale:
IMC Code 801.12 specifies that connectors must connect at least 12 inches above the lowest
portion of the chimney flue to ensure proper draft and prevent smoke backflow.
Question 3 – Combustible Liquid Classification
Liquids having flash points at or above 100°F (38°C) and below 140°F (60°C) come under:
A) Class I
B) Class II
C) Class IIIA
D) Class IIIB
Correct Answer:
B) Class II
Rationale:
Class II combustible liquids are defined as liquids with flash points ≥100°F and <140°F. Proper
identification is critical for safe handling and storage.
Question 4 – Mechanical Draft System Termination
Where located adjacent to walkways, the vertical termination of mechanical draft systems shall
be not less than ______ above the level of the walkway:
, Page 4 of 63
A) 7 feet
B) 5 feet
C) 3 feet
D) 4 feet
Correct Answer:
A) 7 feet
Rationale:
IMC Code 804.3.5.1 requires mechanical draft systems adjacent to walkways to terminate at
least 7 feet above the walkway to prevent hazards to personnel.
Question 5 – Commercial Kitchen Grease Duct Velocity
Commercial kitchen grease duct systems serving a Type I hood shall be designed and installed
to provide an air velocity within the duct system of not less than:
A) 1000 fpm
B) 500 fpm
C) 400 fpm
D) 250 fpm
Correct Answer:
B) 500 fpm
