Q

Regarding the causes of failure of steel, which point(s) are correctly stated as factors?
Select one or more:
a. The greater the supported load, the faster a steel structural member will fail
b. The heat sink property of steel lengthens the time it takes for steel to reach its collapse temperature.

Q

Trenches should be cut with all of the following tactics except?

a. 20 feet from the initial vent hole
b. Taking advantage of outside walls and interior fire walls
c. At the narrowest available roof section
d. With a charged line brought to the roof

Q 
The vertical collapse zone is generally considered to be?
Select one or more:
