(AHJ) in Utah is typically:
A) The local fire department
B) The Utah State Police
C) The Utah Water Conservancy District
D) The Utah Department of Transportation

**Question 6.** NFPA 13 requires a minimum distance of how many inches between a standard
sprinkler head and a wall?
,Utah Fire Suppression Systems S370 Exam
A) 4 in.
B) 6 in.
C) 8 in.
D) 12 in.
**Answer:** B

high rack heights?
A) Standard spray
B) ESFR (Early Suppression Fast Response)
C) Sidewall
D) Pendant
**Answer:** B
