A Knowledge Quiz On Fire Inspection And Code Enforcement Part II - Quiz

Here is a part II to "A Knowledge Quiz On Fire Inspection And Code Enforcement!" Fire is one of the major risks that are facing a building, and this being said, there should be some measures that are put in place to contain it or reduce the chances of it happening. Being that you are training to be a fire inspector, you need to understand the basics of fire inspection and code enforcement. Take it up and see what you know.

From a fire protection perspective, what is the most important factor about trusses?
- A.
  
  Trusses have a proven record of fire safety and are allowed by code for all applications.
- B.
  
  Trusses are typically protected by insulation and thus do not pose a danger to fire crews.
- C.
  
  Trusses use less material and are lighter than a comparable beam or joist for an equal span.
11.

When considering the flame resistance of wood flooring, which of the following statements is MOST accurate?
