Fire can completely demolish buildings but what keeps the fire burning long enough to destroy the building? The answer to that question would be the fire load of the building. The term fire load is defined as the weight of combustible contents per unit floor area (Gross, 1977). The fire load of a building includes anything that is combustible such as finishes, furniture, building materials, etc. These materials are divided into two categories movable contents and interior and exterior finishes. Two types of fire loads must be determined for every building and they are the localized and distributed fire loads. The localized fire load shall be determined to reflect concentrations of combustible material that have the potential to pose a more …show more content…
Having an accurate calculated fire load makes code compliance with the Authority Having Jurisdiction (AHJ) easier. The National Fire Protection Association (NFPA) states that the code gives the minimum requirements necessary to establish a reasonable level of fire and life safety, and property protection (Wolin, 2015). Fire load has to be calculated to insure that every building meets the minimum requirements to preserve life safety. All combustible materials included in the building must be accounted for. Another advantage to knowing the fire load helps to make it easier to plan the layout of the building. When planning the building one of the key components is the means of egress. NFPA States that an exit or mean of egress must be separated from other parts of the building (Wolin 2015). The means of egress needs to have as little of a fire load as possible because it will be the exit route for the people inside in case of a fire. Another advantage to knowing the fire load is it can play a role into determining the flow and direction of a fire if the situation does occur. The fire load helps the firefighters to figure out what their Needed Fire Flow (NFF) in gallons per min (gpm) so that they can attempt to successfully fight the fire and save the building while protecting the lives of the citizens inside. There are …show more content…

One of the deadliest nightclub fires in United States history occurred on May 28, 1977, a busy Memorial Day weekend in the suburbs of Cincinnati. The Beverly Hills Supper Club was a popular nightclub located in Southgate, Campbell County, Kentucky in the greater Cincinnati area. It was located on a hill less than 1000 ft. from the highway on seventeen acres of land just three miles from downtown Cincinnati (Beverly Hills Supper Club Fire D-1). It has since become a case study for its numerous code violations and the behavior of the fire from ignition to building collapse. While there is no one contributing factor to the significant loss of life at this facility, a study of the building’s history, the sequence of the fire’s progression, and an analysis of the fire’s chemistry can provide some valuable lessons to the future firefighter.

In the last eighteen years in Baltimore, lightweight truss construction has become a household name in firefighting. Two reason for this is the amount of new construction in the area and secondly, the unpredictability of lightweight truss failure during fire attack. Brannigan's (2015, p. 202) describes Lightweight wood truss as a 2-inch piece of wood, the lightweight wood truss is pieced together on a factory table and subsequently joined together with light gauge galvanized steel gusset plates. IFSTA states (2015, p. 287) the reduced mass of their components and the interdependence of those components make them vulnerable to early failure under fire conditions. CDC states that that lightweight wood truss can fail early as 6 to 13 minutes
The EIFS, a non-load-bearing wall assembly consists of a layer of expanded polystyrene foam adhered to gypsum sheathing. The polystyrene and polyurethane portions of the EIFS panels and trim burned along the building’s parapet, and melting foam ran down the exterior edge of the hotel, starting fires in other EIFS panels. As the fire spread from the center of the west and south wings of the hotel, it also began to burn downward, exposing the windows of the suites on the 32nd floor. When heat caused several windows on the 32nd floor to fail, flames spread into the building. In several of the suites, sprinklers operated, confining the interior fires and allowing suppression forces to extinguish them.
When the four components of the fire tetrahedron are brought together, ignition occurs. For a fire to grow beyond the first material ignited heat must be transmitted by conduction, convection, or radiation, to additional fuel packages. In the early stages of a fire, heat rises to form a plume of hot gas and products of combustion. Fires in compartments are more complex than those in the open (IFSTA, 2013). In a compartment the plume is affected by the walls and ceiling. As the hot gases rise , they begin to spread outward until they reach the walls. Once the gases reach the walls they are confined and the depth of the gas layer increases from the ceiling towards the floor. If enough fuel and oxygen is available the fire continues to grow, and the overall temperature of the compartment and gas layer increases. The temperatures increase to a point when all combustible materials in the room have reached their own ignition temperatures. Flashover occurs when these materials ignite almost spontaneously. Once ignited and all combustibles in the compartment are burning the fire is said to be fully developed. The fire begins to decay
The purpose of NFPA 25 is: “to provide requirements that ensure a reasonable degree of protection for life and property from fire through minimum inspection, testing, and maintenance methods for water-based fire protection systems” (Klaus, 2014, p. 10). It is significant that NFPA
Most, if not all, of the buildings were constructed of wood and most of them were put on man-made lands with very unstable soil. The buildings that were constructed of steel or brick were next to wood buildings too. All of these buildings lacked proper fire safety equipment like fire-sprinklers and the city streets were very narrow making it easy for fire to spread. Out of all the buildings in San Francisco at this time under two percent of them were considered to be fireproof (52).Working class and immigrant families at this time were living in these poorly constructed buildings often with many families assigned to one single room. These conditions made it almost impossible for them to have a chance of hope when the deadly San Francisco Earthquake of 1906
Particularly, in ceilings and cockloft area, rapid fire extension is created by the heavy fire load in the confined and open area. (Christopher J. Naum, 2008) Besides flames being undetectable in these confined spaces, it also traps superheated gases creating a possibility of a flashover in concealed spaces including between the ceiling and floors. Another hazard in Type III buildings that effect firefighting is during roof operation in the darkness, a firefighter can step off the edge of a roof or stumble over a low parapet. (IFSTA, 2016, p. 279) Furthermore, The collapse danger of the parapet wall is one of the reasons why the area directly in front of a fire building is so dangerous, and why firefighters are urged either to move inside the doorway or away from the front of the building altogether. (Christopher J. Naum,
All fire departments should have a set of standard operating procedures (SOP’s) that serve as a frame of reference for firefighters when determining how best to handle a fire situation. Venting for life is a situation that is routinely part of those SOP’s. The Jefferson Parish Louisiana Fire Departments SOP’s relating to venting for life states: “Firefighters may create openings, or break windows, to gain access from an exterior position to carry out a primary search in a high-risk area of the structure.” These openings are most often windows that can be in an area adjacent to the fire or in another area of the fire building that is deemed most effective. This method of ventilation is called V-E-S (vent, enter, search) and while it is a common practice among fire departments it is a strategy that is often filled with hazards but may produce great rewa...
Protection is explicitly extended to all occupants, which would include employees, visitors, contractors and passers-by who would all have to be considered in the fire risk assessment. What are the implications for business?

According to the National Fire Protection Association (NFPA), a fire is any process of uncontrollable combustion or burning. A structural fire, refers to any fire occurring in or on a structure, including, if this is limited to the contents. Fire spread rapidly, causing economic losses, injury and even death. The majority of the injuries or deaths caused by fire, occur in the home, either in properties of one, two or multiple families, especially while people are sleeping. In addition, the risk of injury or death does not have a uniform distribution between populations. This varies between age groups, race, religion, cause of the fire and size of the community (Ahrens, 2014).
When a fire occurs in a home, the aftermath can seem overwhelming. The extent and severity of fire and smoke damage that can take place during a fire can leave behind soot, debris, odor, and smoke. Even in areas that seem to be unharmed by the fire and smoke can create a dangerous and hazardous environment. This not only can damage to a home’s structure, it can also damage the contents and personal belongings inside. When fire damage occurs, immediate response is necessary to mitigate the damages as well as prevent further damage from occurring.
