The purposes of fire-resistance requirements in the building code include which of the following? check all that apply.
A. To permit safe evacuation of the occupants
B. To prevent fire damage to the building
C. To reduce the generation of toxic smoke
D. To prevent structural failure for a specified period of time
The answer is A and D. It says Fire resistance requirements relate primarily to life safety, and only secondarily to structural damage.
I thought the answer is ALL. I still don't understand why B and C are not included. Both also affect a person life safety. Fire damage to building is the same as D structural failure; toxic smoke affect breathing.
Can someone tell me why? Thanks in advance.
