Accepted Answer

60 feet

Answer

1.5 times 40 feet equals 60 feet, which is the minimum collapse zone required.

Question 2

A map legend shows: blue lines = water mains, red circles = hydrants, yellow triangles = shut-off valves. On the map you see a red circle where two blue lines intersect. What does that symbol represent?

Accepted Answer

A fire hydrant at the intersection of two water mains

Answer

The passage states fresh air introduced to an oxygen-depleted smoldering fire causes backdraft, which happens when a door or window is opened.
