A common question we hear is “why is the code handbook so much bigger than the code?” To really see the difference, let’s look at one specific section of a code and the corresponding material found in the handbook.

And to give an even deeper understanding of the requirement, in the handbook this code section also has an NFPA 13 Lesson to explain how to determine sprinkler spacing and location:
While this example is specific to NFPA 13 and the 2016 edition of that handbook, every NFPA handbook is different and each one offers unique features and material to help you understand the code requirements.
