While it seems like common sense for inspectors to identify sprinkler system design deficiencies, they are not part of the scope of NFPA 25, Water-Based Fire Protection Systems. From an inspection standpoint, NFPA 25 is not a design evaluation standard, a differentiation that often leaves people scratching their heads. While design deficiencies can create serious life safety concerns and have contributed to the failure of water-based fire protection systems, it is important to understand where these issues should be documented, and by whom. To find out who is responsible, read "Too Much of a Good Thing?" by Matt Klaus in the latest issue of NFPA Journal.
