An understanding of the intent of NFPA codes and standards is something a fire safety professional must possess. In today's world, where operational and financial efficiencies are important factors to the E suite, fire safety professionals must balance the effort needed to perform required inspections, maintenance, and testing while ensuring fire safety systems provide their designed life safety protection without fault.

This article will discuss how main drain tests in most high-rise buildings that have combined sprinkler/hose standpipe systems with large supply pipes (6 inches diameter or greater) may not be as effective of a test as the writers of the standards intended. For systems connected to a fire pump that is fed from a supply tank (which, in turn, is automatically refilled by a municipal water supply), main drains provide no added assurance of the system's reliability.

This brief was excerpted from the December issue of Healthcare Life Safety Compliance.
