Fire Protection Systems

Hi,   Scale and corrosion can form inside system piping. Dry sprinkler systems in particular are subject to the formation of scale because the condensation of moisture in the air supply reacts with the inner surface of the steel pipe. In many cases, dry systems are installed with galvanized pipe to prevent scaling. Untreated water from natural…

Refer to 2015 IFC 905.3.1 for when a standpipe is required, when finished floor elevation is greater than 30'-0" above lowest level of fire department access. So it is possible that a 3 story hotel could have a finished 3rd level at 20'-0" above lowest level of fire department access, which would Not require a standpipe.   For a Non-High Rise…

You'd read NFPA 101.

As humans are part of the environment, the safety in use of clean agents is a primary concern. FM-200 is characterized by superior safety in use (lower toxicity) vs Novec 1230, as measured by a number of toxicological endpoints, including  short term inhalation (LC50), 28 day inhalation, Physiologically-based Pharmacokinetics (PBPK), cardiac…

Codes also refer them as utility chases. For fire protection, to me, the occupancy the chase (tunnel) is integrated  within a building that is required to protected by a NFPA 13 sprinkler system, the tunnel is to be protected by that sprinkler system. The AHJ may require the tunnel to be classified as an ordinary hazard for sprinkler system…
