  • NFPA 13 – 2016 Faqs
    NFPA 13 – 2016 FAQs Responses to FAQs are prepared by NFPA technical staff to assist users in reading and understanding NFPA codes and standards. The responses, however, are not Formal Interpretations issued pursuant to NFPA Regulations. Any opinions expressed are the personal opinions of the author(s), and do not necessarily represent the official position of the NFPA or its Technical Committees. In addition, the responses are neither intended, nor should be relied upon, to provide professional consultation or services. 1. Do I need sprinklers in my building? NFPA 13 is an installation standard and does not specify which buildings or structures require a sprinkler system. NFPA 13 specifies how to properly design and install a sprinkler system using the proper components and materials after it has been determined that a sprinkler system is required. The administrative authority for requiring sprinklers within buildings rests with any of the following: the local building code, NFPA 5000, NFPA 101, International Building Code, or insurance regulations that typically specify which buildings and structures require sprinkler systems. Where the building code does not require a sprinkler system but one is installed voluntarily, the requirements of NFPA 13 still apply to the portion of the building being protected. 2. If I have a dry‐pipe sprinkler system under a pitched roof exceeding a slope of 16.7%, do I apply both area increases from Section 11.2.3.2.4 and Section 11.2.3.2.5? Yes, both sections would be applied cumulatively to the design area chosen from Figure 11.2.3.1.1 in accordance with Section 11.2.3.2.7.

  • Supplement 4
    SUPPLEMENT 4 Residential Sprinkler Systems John L. Bryan Editor’s Note: Supplement 4 is a reprint of Chapter 10 in the fourth edition of NFPA’s book, Automatic Sprinkler and Standpipe Systems. This material provides a historical perspective of the development of residential sprinklers and standards. This supplement provides details of specific residential fire tests used in the development of the initial residential sprinkler technology and reviews residential sprinkler incentives, tradeoffs, activations, and code adoptions across the United States. This supplement also provides an overview of NFPA residential sprinkler requirements and applications. The first edition of NFPA 13D, Standard for the Installation SPRINKLER SYSTEMS FOR DWELLINGS of Sprinkler Systems in One- and Two-Family Dwellings Fire Death and Injury Data and Manufactured Homes, issued in 1975, exempted cer- tain portions of dwellings from sprinkler coverage based on More than four of every five dwelling fire fatalities (ap- the established fire hazard record.

  • Passive Firestop Systems Critical for Building Occupants
    10/23/13 4:29 PM Passive firestop systems critical for building occupants By Gregg Stahl Instruments of active fire protection, such as sprinkler systems and fire extinguishers, are a common sight in most buildings – they are always located where building occupants can easily see and access them, if needed. Not as much attention is given to passive fire protection systems, embedded into interior building assemblies, away from public view. However, they are just as integral to the protection of the structure and its occupants in the event of a fire. A key component of commercial building design, passive fire protection's aim is to contain a fire at its source and prevent the spread of flames and smoke throughout a building to allow occupants more time to safely evacuate the structure. The most important area of concentration for these passive fire protection design strategies is the wall assembly, and the most effective mode of passive fire protection is the passive firestop system. Passive firestop systems Fire and smoke can travel through gaps in wall assemblies. Therefore, it is necessary to seal off any wall perimeter joints or penetrations for switches, electrical boxes, power outlets or the passage of pipes, cables or HVAC ductwork with firestop materials. Typically, these materials include: sealants, intumescent materials, sprays, mechanical devices and foam blocks or pillows. It is important to remember that there isn't one universal product that will work for every firestop application. It is also important to select products that have been tested appropriately to meet applicable fire safety standards. The two materials most commonly used in passive firestop systems for today's commercial building projects are sealants and intumescent materials.

  • Residential Fire Sprinkler Fact Sheet Are Home Fire Sprinklers a Reasonable Option for Your New Home?
    BBBeee IIInnnfffooorrrmmmeeeddd aaannnddd CCChhhoooooossseee WWWiiissseeelllyyy Residential Fire Sprinkler Fact Sheet Are Home fire Sprinklers a Reasonable Option for Your New Home? Residential fire sprinklers are not new technology for preserving property and promoting life safety, but the modern systems that utilize the domestic plumbing system pipes for the sprinkler water have drastically reduced the cost of the materials and simplified the installation. Your new home may be well served by a fire sprinkler system and your builder has the capability to include a very simple sprinkler system that is highly effective in protecting your family and your property. The cost of the system is at an all time low and the systems are unquestionably reliable. The experts all agree that fire sprinklers and smoke detectors work together to provide absolutely the safest home available today from a fire safety standpoint. The code officials that develop the national building codes all agree that fire sprinklers need to be in all new homes and they are so convinced that they have seen fit to require sprinklers in all three model building codes in use in the USA today. Some jurisdictions have allowed the builders and home buyers to choose whether to include the sprinklers in their new homes by creating a choice option for you and your family. By presenting this information your builder is allowing you the opportunity to develop an informed opinion concerning the needs of your family. This educational brochure is intended to share the facts about fire sprinklers so as to better equip you in determining if you think sprinklers are a good choice for your family and your new home.

  • Active and Passive Fire Protection Systems WHITE PAPER
    WHITE PAPER Active and Passive Fire Protection Systems Active and passive fire protection systems work in tandem and play a key role in a comprehensive life safety plan for a commercial facility. Active and Passive Fire Protection Systems WHITE PAPER According to the National Fire Prevention Association (NFPA), smoke and toxic gases are the most significant factors in loss- of-life fires. Almost 70% of all building deaths are associated with smoke inhalation.* 70% The prompt and safe evacuation of building occupants and immediate of all building notification of the fire department are the primary means to prevent loss of life, as well as loss of property. The principles for saving building occupants from a fire deaths are are delineated in NFPA 101, Life Safety Code, and NFPA 72 for fire alarm systems. associated with Working in tandem with the alarm and detection systems are sprinkler systems. smoke inhalation When inspected and maintained properly, and ensured they haven’t been tampered with, sprinkler systems are designed to extinguish a fire. When a certain temperature is reached, a sprinkler head will activate and water will begin flowing, helping to put out the fire. NFPA 25 covers inspection requirements for sprinkler systems. Compliance helps maximize system integrity to avoid failure and ensure fast, effective response to a fire emergency. Principles for Another layer of protection is required, often referred to as “defend in place.” saving building In the event that a life safety system fails, is tampered with, or in a situation in which occupants in a facility cannot be easily evacuated, as is the case for the occupants ambulatory, elderly, incarcerated and others, passive fire protection can play from a fire are a key role in saving lives.
