However, by applying the obstruction and clearance principles the solution will make itself clear.A fire sprinkler system is an active fire protection measure, consisting of a water supply, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected.

The solution to these challenges are not always easily found clearly in the pages of NFPA 13. These cloud ceilings present unique challenges to fire sprinkler installation. Then it must be determined if the obstruction is continuous or noncontinuous.Ĭloud ceiling: a suspended ceiling that covers only a portion of a room or space below To determine the proper application it must first be determined if the construction is obstructed or unobstructed. NFPA 13, Standard for the Installation of Sprinkler Systems, provides sprinkler coverage guidance for these obstructed areas. However, these buildings and elements must still be protected.

Inherent building construction or design elements can pose potential obstructions to the full coverage or discharge pattern of the sprinkler system. A fire sprinkler system should be designed in a manner that provides full water coverage from the fire sprinkler system. Important to fire sprinkler effectiveness is sprinkler discharge pattern development. Sprinkler Obstructions and Discharge Patterns To determine which chapter to go to for fire protection requirements, there are three questions that must be answered: Chapter 17, Protection of Rack Storage of Plastic and Rubber Commodities.Chapter 16, Protection of Rack Storage of Class I through Class IV Commodities.Chapter 15, Protection for Palletized, Solid-Piled, Bin Box, Shelf, or Back-to-Back Shelf Storage of Plastic and Rubber Commodities.Chapter 14, Protection for Palletized, Solid-Piled, Bin Box, Shelf, or Back-to-Back Shelf Storage of Class I through Class IV Commodities.Chapter 13, Protection of Miscellaneous and Low-Piled Storage.What are the requirements for rack storage? Are in-rack sprinklers required? How can rack storage sprinkler requirements be determined?įire protection requirements for rack storage are addressed in NFPA 13, Standard for the Installation of Sprinkler Systems. NFPA 13, Standard for the Installation of Sprinkler Systems, requires all plastics, elastomers, and rubber, to be classified as Group A, Group B, or Group C.įire Protection Requirements for Rack Storage Due to the high speed and temperature of burning plastics, they require special consideration. For the protection of rack storage, the storage and shelving configuration must be known. To provide effective fire sprinkler protection within a structure, the hazard classification and commodity must be known. This slideshow presentation can be utilized as a reference to quickly review and confirm occupancy and commodity classifications. In book form, this information can sometimes be difficult to recall. NFPA 13, Standard for the Installation of Sprinkler Systems, chapter five defines occupancy hazard and commodities classifications for the design and installation of sprinkler systems. Are these classifications correct based on the use of the structure? Or, you are sitting down to do a plan review, the occupancy hazard and commodity class is listed. Perhaps you are conducting a fire inspection or survey and you notice that the hazard or commodity classification on the hydraulic calculation plate at the riser seems odd for the actual contents of the structure.

The below is a tool that can be used as a quick guide to what occupancies require fire sprinklers, and where the code can be referenced.ĭownload the sprinkler requirements guide. However, in order to find where they are, or may be, required, involves some searching through the code book. Reading through the NFPA standards, one consistently comes upon the phrase "sprinklers where required". This convenient tool eliminates the need to search multiple pages for clarifications by listing the most used terms and definitions on a single page.
