Tom, The groups are only for calculations. The pipe schedule system was only listed as Light, Ordinary and Extra Hazard.

Per sprinkler with O.H. pipe sizing." My question is the plans do not mention Group 1 or Group 2.How do I know if the O.H.(ordinary hazard is group 1 or 2)? Based on NFPA 13(2010) different occupancies are allowed for group 1 and group 2.Thanks Wheeling Fire Inspector Tom Reinhardt 2 Community Boulevard Wheeling, IL 60090 847-499-9067 ________________________________ IMPORTANT NOTICE: This e-mail message is intended to be received only by persons entitled to receive the confidential information it may contain.
