OSFMFEI-07 FLAME RETARDANT APPLICATOR (LIMITED) VERIFIED QUESTIONS AND ANSWERS FOR EASY EXAM PASS

1. The primary purpose of a flame retardant is to:
A. Make materials fireproof
B. Slow ignition and fire spread
C. Increase material strength
D. Improve appearance
ANSWER : B
Explanation: Flame retardants do not make materials fireproof; they slow
ignition and reduce flame spread, giving occupants time to escape.


2. Flame retardants work mainly by:
A. Increasing oxygen supply
B. Lowering ignition temperature
C. Interfering with combustion
D. Adding fuel to the fire
ANSWER : C
Explanation: Flame retardants interrupt the combustion process, often by
forming a protective char layer or releasing fire-suppressing gases.


3. Which material commonly requires flame retardant treatment?
A. Glass
B. Steel
C. Wood framing
D. Concrete
ANSWER : C
Explanation: Wood framing is combustible and commonly treated to reduce
fire spread.

,4. OSFM stands for:
A. Office of State Fire Management
B. Office of the State Fire Marshal
C. Occupational Safety Fire Manual
D. Official Safety Fire Measure
ANSWER : B
Explanation: OSFM is the Office of the State Fire Marshal, which regulates
fire safety programs.


5. A “limited” flame retardant applicator license allows:
A. Structural engineering design
B. Fire sprinkler installation
C. Application of approved flame retardants only
D. Fire investigation work
ANSWER : C
Explanation: A limited license restricts work to application of approved
flame retardant chemicals, not design or inspection.


6. Flame spread rating is determined by:
A. Smoke color
B. Heat release only
C. Surface burning characteristics
D. Weight of material
ANSWER : C
Explanation: Flame spread rating measures how fast flames travel across a
surface.


7. Which test is commonly used for flame spread?
A. ASTM E84
B. ASTM A36
C. NFPA 70
D. OSHA 1910

,ANSWER : A
Explanation: ASTM E84 (Steiner Tunnel Test) measures flame spread and
smoke development.


8. A Class A flame spread rating is:
A. 0–25
B. 26–75
C. 76–200
D. Over 200
ANSWER : A
Explanation: Class A (0–25) offers the highest fire resistance.


9. Flame retardant chemicals must be:
A. Mixed on site without approval
B. Approved by the OSFM
C. Imported without documentation
