A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected. Although historically only used in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. Even though Fire Sprinkler Systems are a Life Saving System and are not designed to protect the building, 96% of buildings that had fires and were completely protected by fire sprinkler systems were controlled by the fire sprinklers alone.
A fire marshal or fire commissioner, in the United States and Canada, is often a member of a state, provincial or territorial government, but may be part of a building department or a separate department altogether. Fire marshals' duties vary but usually include fire code enforcement or investigating fires for origin and cause. Fire marshals may be sworn law-enforcement officers and are often experienced firefighters. In larger cities with substantially developed fire departments the local fire departments are sometimes delegated some of the duties of the fire marshal.
A fire alarm notification appliance is an active fire protection component of a fire alarm system. A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire or other emergency condition requiring action. Audible appliances have been in use longer than any other method of notification. Initially, all appliances were either electromechanical horns or electric bells, which would later be replaced by electronic sounders. Most of today's appliances produce sound pressure levels between 45 and 120 decibels at ten feet.
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association. Despite the use of the term "national", it is not a federal law. It is typically adopted by states and municipalities in an effort to standardize their enforcement of safe electrical practices. In some cases, the NEC is amended, altered and may even be rejected in lieu of regional regulations as voted on by local governing bodies.
Fire safety is the set of practices intended to reduce the destruction caused by fire. Fire safety measures include those that are intended to prevent ignition of an uncontrolled fire, and those that are used to limit the development and effects of a fire after it starts.
"NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association. First "tentatively adopted as a guide" in 1960, and revised several times since then, it defines the colloquial "Safety Square" or "Fire Diamond" used by emergency personnel to quickly and easily identify the risks posed by hazardous materials. This helps determine what, if any, special equipment should be used, procedures followed, or precautions taken during the initial stages of an emergency response.
The publication Life Safety Code, known as NFPA 101, is a consensus standard widely adopted in the United States. It is administered, trademarked, copyrighted, and published by the National Fire Protection Association and, like many NFPA documents, is systematically revised on a three-year cycle.
The International Building Code (IBC) is a model building code developed by the International Code Council (ICC). It has been adopted for use as a base code standard by most jurisdictions in the United States. The IBC addresses both health and safety concerns for buildings based upon prescriptive and performance related requirements. The IBC is fully compatible with all other published ICC codes. The code provisions are intended to protect public health and safety while avoiding both unnecessary costs and preferential treatment of specific materials or methods of construction. However, a 2019 New York Times story revealed a secret agreement with the National Association of Home Builders that allowed the industry group, which represents the construction industry, to limit improvements in the code that would make buildings more environmentally sustainable and resistant to natural disasters, prompting a congressional investigation. The ICC, in response to a Congressional inquiry, vehemently denied the characterization of the agreement, noting, "While home builders are among [our code development] partners, they do not have disproportionate control of the Code Council’s model code development process. On the contrary, volunteer government officials with experience and expertise exercise by far the most control in the process."
NFPA 70E, titled Standard for Electrical Safety in the Workplace, is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for publishing the National Electrical Code.
Fire investigation, sometimes referred to as origin and cause investigation, is the analysis of fire-related incidents. After firefighters extinguish a fire, an investigation is launched to determine the origin and cause of the fire or explosion. Investigations of such incidents require a systematic approach and knowledge of basic fire science.
Arc mapping is a technique used in fire investigation that relies on finding the locations of electrical arcs and other electrical faults that occurred during a fire; the locations of the electrical faults can then, under some circumstances, indicate the progression of the fire over time. It is usually performed by a forensic electrical engineer. It The technique relies on the assumption that, when heat from fire impinges on an electrical line, it will melt the wire insulation and cause an electrical fault at the first point that it reaches on the electrical line. For this to occur, the electrical line must be energized at the time that fire hits it.
The Hazardous Materials Identification System (HMIS) is a numerical hazard rating that incorporates the use of labels with color developed by the American Coatings Association as a compliance aid for the OSHA Hazard Communication (HazCom) Standard.
Forensic electrical engineering is a branch of forensic engineering, and is concerned with investigating electrical failures and accidents in a legal context. Many forensic electrical engineering investigations apply to fires suspected to be caused by electrical failures. Forensic electrical engineers are most commonly retained by insurance companies or attorneys representing insurance companies, or by manufacturers or contractors defending themselves against subrogation by insurance companies. Other areas of investigation include accident investigation involving electrocution, and intellectual property disputes such as patent actions. Additionally, since electrical fires are most often cited as the cause for "suspect" fires an electrical engineer is often employed to evaluate the electrical equipment and systems to determine whether the cause of the fire was electrical in nature.
Kirk's Fire Investigation by David J. Icove and Gerald A. Haynes has long been regarded as the primary textbook in the field of fire investigation. It is currently in its 8th edition.
The International Association of Arson Investigators is a professional association of individuals who conduct fire investigations. The IAAI provides resources for training, research, and technology for fire investigators around the world. It is based in Crofton, Maryland, United States.
The National Association of Fire Investigators (NAFI) is a professional association of people who investigate cases of fire and arson. It was created in 1961 and is located in Bradenton, Florida. The purpose of the group is to increase knowledge and improve skills of fire investigators in the field and in relation to the litigation involved in determining the origin and cause of fires.
A combustible material is something that can burn in air. A combustible material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
The Fire Sprinkler Incentive Act (FSIA) is the name of a piece of legislation that has been introduced in both the House and the Senate since 2003. The legislation would amend the 1986 Internal Revenue Code by classifying fire sprinkler retrofits as either a Section 179 depreciation deduction or a fifteen-year property for purposes of depreciation. Currently the tax depreciation time for commercial property is 39 years and 27.5 for residential.
The 1978 Holiday Inn fire broke out at a Holiday Inn hotel located at 1525 West Ridge Road in the town of Greece, New York, United States, on November 26, 1978. The fire was considered notable enough by the National Fire Protection Association (NFPA) and the Center for Fire Research to document the fire in their 1979 publications. In the end, ten people were killed and 34 injured; seven of the fatalities were Canadian nationals. In 2008, the NFPA listed the 1978 Holiday Inn fire as one of only three dozen or so fires which killed ten or more people in the U.S. between 1934 and 2006.
