two parts.
The first part is 50 questions and they are all
multiple choice.
The second part is 25 questions and they are all
true false.
The first part of the test is primarily from the NFPA

They will give you a National Fire Code, an
International Fire Code, A copy of the Denver

You will need the International Fire Code and
the Denver Building Amendments for the last
25 true/false questions.

 909 of the International Fire Code
 For sections 907 and 909 you can use the
index in the International Fire Code.
NFPA 72 The
National Fire
Alarm Code
The first part of the test.
All questions are multiple choice.
Beware: They will give you a 2007
NFPA 72 but the questions are
based on the 2004 NFPA 72.

Every code cycle the Denver Fire Department
uses a system of modification to amend the
International Fire Code.
This results in the Denver Building
Amendments.
This is typically a 300 + page document but
we only need to concern ourselves with the
amendments to the IFC portion
You have a copy of that and will be given a
copy for the test
