CHAPTER 11 Flashcards
The most serious defect is the
Sheet metal fasteners
1/4 to 1/2 inch deep
First to fail in a fire
These fasteners may also rust and weaken when properly installed in an enclosed well insulated roof space
What is the main concern to the fire service about lightweight wood truss construction
The sheet metal fasteners that connect the truss members
NY State has a law that requires buildings with trusses be marked with
2 vertical lines
The strategy for a fire that involves the STRUCTURE in a light weight wood truss construction is to
Remove personnel from the building and conduct an exterior attack
The rate of fire spread inside a buildings concealed space will be
(Parallel chord lightweight truss)
100% faster than in concealed spaces of a building with conventional solid wood beam construction
