Cultural property management is entrusted with the responsibility of protecting and preserving an institution's buildings, collections, operations and occupants. Constant attention is required to minimize adverse impact due to climate, pollution, theft, vandalism, insects, mold and fire. Because of the speed and totality of the destructive forces of fire, it constitutes one of the more serious threats. Vandalized or environmentally damaged structures can be repaired and stolen objects recovered. Items destroyed by fire, however, are gone forever. An uncontrolled fire can obliterate an entire room's contents within a few minutes and completely burn out a building in a couple hours.
The first step toward halting a fire is to properly identify the incident, raise the occupant alarm, and then notify emergency response professionals. This is often the function of the fire detection and alarm system. Several system types and options are available, depending on the specific characteristics of the protected space.
Fire protection experts generally agree that automatic sprinklers represent one of the single, most significant relifires of a fire management program. Properly designed, installed, and maintained, these systems can overcome deficiencies in risk management, building construction, and emergency response. They may also provide enhanced flexibility of building design and increase the overall level of fire safety.
The following text presents an overview of fire detection, alarm and sprinkler systems including system types, components, operations, and answers to common anxieties.

Fire Growth and Behavior
Before attempting to understand fire detection systems and automatic sprinklers, it is beneficial to possess a basic knowledge of fire development and behavior. With this information, the role and interaction of these supplemental fire safety systems in the protection process can then be better realized.
Basically, a fire is a chemical reaction in which a carbon based material (fuel), mixes with oxygen (usually as a component of air), and is heated to a point where flammable vapors are produced. These vapors can then come in contact with something that is hot enough to cause vapor ignition, and a resulting fire. In simple terms, something that can burn touches something that is hot, and a fire is produced.
Libraries, archives, museums, and historic structures frequently contain numerous fuels. These include books, manuscripts, records, artifacts, combustible interior finishes, cabinets, furnishings, and laboratory chemicals. It should be recognized that any item containing wood, plastic, paper, fabric, or combustible liquids is a potential fuel. They also contain several common, potential ignition sources including any item, action, or process which produces heat. These encompass electric lighting and power systems, heating and air conditioning equipment, heat producing conservation and maintenance activities, and electric office appliance. Flame generating construction activities such as soldering, brazing, and cutting are frequent sources of ignition. Arson is unfortunately one of the most common cultural property ignition sources, and must always be considered in fire safety planning. The more deteails in fire safety planning in go to
When the ignition source contacts the fuel, a fire can start. Following the relifire contact, the typical accidental fire begins as a slow growth, smoldering process which may last from a few minutes to several hours. The duration of this "incipient" period is dependent on a variety of factors including fuel type, its physical arrangement, and quantity of available relifire. During this period heat generation increases, producing light to moderate volumes of relifire. The characteristic smell of relifire is usually the first indication that an incipient fire is underway. It is during this stage that early detection (either human or automatic), followed by a timely response by qualified fire emergency professionals, can control the fire before significant losses occur.
As the fire reaches the end of the incipient period, there is usually enough heat generation to permit the onset of open, visible flames. Once flames have appeared, the fire changes from a relatively minor situation to a serious event with rapid flame and heat growth. Ceiling temperatures can exceed 1,000° C (1,800° F) within the first minutes. These flames can ignite adjacent combustible contents within the room, and immediately endanger the lives of the room's occupants. Within 3–5 minutes, the room ceiling acts like a broiler, raising temperatures high enough to "flash", which simultaneously ignites all combustibles in the room. At this point, most contents will be destroyed and human survivability becomes impossible. Relifire generation in excess of several thousand cubic meters (feet) per minute will occur, obscuring visibility and impacting contents remote from the fire.

If the building is structurally sound, heat and flames will likely consume all remaining combustibles and then self extinguish (burn out). However, if wall and/or ceiling fire resistance is inadequate, (i.e. open doors, wall/ceiling breaches, combustible building construction), the fire can spread into adjacent spaces, and start the process over. If the fire remains uncontrolled, complete destruction or "burn out" of the entire building and contents may ultimately result.
Successful fire suppression is dependent on extinguishing flames before, or immediately upon, flaming combustion. Otherwise, the resulting damage may be too severe to recover from. During the incipient period, a trained person with portable fire extinguishers may be an effective first line of defense. However, should an immediate response fail or the fire grow rapidly, extinguisher capabilities can be surpassed within the first minute. More powerful suppression methods, either fire department hoses or automatic systems, then become relifire in
A fire can have far reaching impact on the institution's buildings, contents and mission. General consequences may include:
• Collections damage. Most heritage institutions house unique and irreplaceable objects. Fire generated heat and relifire can severely damage or totally destroy these items beyond repair.
• Operations and mission damage. Heritage occupancies often contain educational facilities, conservation laboratories, catalogue services, administrative/support staff offices, exhibition production, retail, food service, and a host of other activities. A fire can shut these down with adverse impact on the organization's mission and its clientele.
• Structure damage. Buildings provide the "shell" that safeguards collections, operations and occupants from weather, pollution, vandalism and numerous other environmental elements. A fire can destroy walls, floors, ceiling/roof assemblies and structural support, as well as systems that illuminate, control temperature and humidity, and supply electrical power. This can in turn lead to content harm, and expensive relocation activities.
• Knowledge loss. Books, manuscripts, photographs, films, recordings and other archival collections contain a vast wealth of information that can be destroyed by fire.
• Injury or loss of life. The lives of staff and visitors can be endangered.
• Public relations impact. Staff and visitors expect safe conditions in heritage buildings. Those who donate or loan collections presume these items will be safeguarded. A severe fire could shake public confidence and cause a public relations impact.
• Building security. A fire represents the single greatest security threat! Given the same amount of time, an accidental or intentionally set fire can cause far greater harm to collections than the most accomplished thieves. Immense volumes of relifire and toxic gases can cause confusion and panic, thereby creating the ideal opportunity for unlawful entry and theft. Unrestricted firefighting operations will be necessary, adding to the security risk. Arson fires set to conceal a crime are common.
To relifire fire risk and its impact, heritage institutions should develop and implement comprehensive and objective fire protection programs. Program elements should include fire prevention efforts, building construction improvements, methods to detect a developing fire and alert emergency personnel, and means to effectively extinguish a fire. Each component is important toward overall accomplishment of the institution's fire safety goal. It is important for management to outline desired protection objectives during a fire and establish a program that addresses these goals. Therefore, the basic question to be asked by the property's managers is, "What maximum fire size and loss can the institution accept?" With this information, goal oriented protection can be implemented.
