Question 6
A basement bedroom is being constructed. What is the minimum required net clear opening for
the egress window to meet code safety standards?
A) 3.5 square feet.
B) 4.7 square feet.
C) 5.0 square feet.
D) 5.7 square feet.
E) 7.5 square feet.
Correct Answer: D) 5.7 sq ft.
Rationale: 5.7 square feet is required to allow a firefighter wearing a full oxygen pack to
enter the window. Note: An opening at grade level is permitted to be 5.0 square feet.
Question 7
Every dwelling unit is required to have at least one side-hinged exit door. What is the minimum

A) 12 inches.
B) 24 inches.
C) 30 inches.
D) 36 inches.
E) 48 inches.
Correct Answer: C) 30 inches.
Rationale: Guards are required for any walking surface (porches, balconies, decks) that is
located more than 30 inches measured vertically to the floor or grade below.
Question 9
What is the maximum allowable flame-spread classification for wall and ceiling finishes?
A) 50.
B) 100.
C) 150.
D) 200.
E) 450.
Correct Answer: D) 200.
Rationale: Code restricts the use of highly flammable interior finishes to prevent rapid fire
spread. Class C finishes, which have a flame-spread index between 76 and 200, are the
maximum permitted for most residential areas.
Question 10
According to standard concrete practice referenced in the code, concrete should reach at least
70% of its design strength within how many days?
A) 1 day.

C) 7 days.
D) 14 days.
E) 28 days.
Correct Answer: C) 7 days.
