NFPA 220 is over what? - ANSWERStandard on types of building construction
In NFPA 220, each classification is designated by a _______________? -
ANSWERThree digit number
,Explain to me what each digit stands for in the NFPA 220 3-digit class -
ANSWER1st digit: Fire resistive rating (in hours) of exterior bearing walls
2nd digit: Fire resistive rating of structural frames or columns and girders that
support loads of more than 1 floor
