CFPS Passive Fire Protection 2 — Questions and Answers
Question 1: What is the primary characteristic that distinguishes a fire wall from a fire barrier under the International Building Code?
- A fire wall must be of noncombustible construction in all cases
- A fire wall must be structurally independent so that collapse of construction on either side does not cause the wall to fail (Correct answer)
- A fire wall requires a minimum 4-hour rating regardless of occupancy
- A fire wall must extend from the foundation to the highest point of the roof
Correct answer: A fire wall must be structurally independent so that collapse of construction on either side does not cause the wall to fail
Per IBC Section 706, fire walls must be structurally independent so that collapse of construction on either side will not cause the wall to collapse.
Question 2: What minimum fire-resistance rating does the IBC require for a smoke barrier in a healthcare occupancy?
- No rating required
- 30 minutes
- 1 hour (Correct answer)
- 2 hours
Correct answer: 1 hour
IBC Section 709.4 requires smoke barriers to have a minimum fire-resistance rating of 1 hour.
Question 3: Per IBC Section 407, what is the maximum allowable area for a single smoke compartment in a hospital (Group I-2 occupancy)?
- 10,000 square feet
- 15,000 square feet
- 22,500 square feet (Correct answer)
- 40,000 square feet
Correct answer: 22,500 square feet
IBC Section 407.5.1 limits each smoke compartment in a Group I-2 occupancy to a maximum of 22,500 square feet.
Question 4: Which primary ASTM standard establishes the test method for determining fire resistance of building construction elements such as walls, floors, and columns?
- ASTM E84
- ASTM E119 (Correct answer)
- ASTM E814
- ASTM E1529
Correct answer: ASTM E119
ASTM E119 (Standard Test Methods for Fire Tests of Building Construction and Materials) is the foundational standard for evaluating fire-resistance ratings of building assemblies.
Question 5: A fire partition used to separate individual dwelling units in a residential occupancy must have a minimum fire-resistance rating of:
- 20 minutes
- 30 minutes
- 45 minutes
- 1 hour (Correct answer)
Correct answer: 1 hour
IBC Section 708.4 requires fire partitions separating dwelling units to have a minimum 1-hour fire-resistance rating.
Question 6: Under the IBC, which of the following correctly describes the role of compartmentalization as a passive fire protection strategy?
- Dividing a building into discrete areas bounded by fire-rated assemblies to limit the spread of fire and smoke (Correct answer)
- Installing automatic sprinklers in each room to suppress fire before it spreads
- Using mechanical pressurization to prevent smoke migration between floors
- Positioning manual pull stations at building exits to trigger early evacuation
Correct answer: Dividing a building into discrete areas bounded by fire-rated assemblies to limit the spread of fire and smoke
Compartmentalization uses fire-rated barriers, walls, and floors to divide buildings into defined areas, limiting fire and smoke spread without active systems.
Question 7: Which IBC assembly type is specifically required to run continuously from the foundation slab to the underside of the roof deck and is intended to create separate buildings?
- Fire barrier
- Fire partition
- Smoke barrier
- Fire wall (Correct answer)
Correct answer: Fire wall
Per IBC Section 706, a fire wall is designed to divide a building into separate fire areas and must extend from foundation to roof with structural independence.
