This study examines the human behavior during an evacuation from a building fire and how each reaction affects the ability for the occupant to evacuate the building safely. Many deaths have occurred when people are unable to escape from a burning building, due to the improper building design, fire detection and suppression systems, and visibility of exit doors and signs. According to Fire enthusiast, the major contributing factors that leads to a tragic evacuation is lack of sufficient exits for the population, lack of direction for egress, lack of fire walls, fire doors and smoke doors and not having an evacuation plan. This should be a topic of concern, because many people die each year in house fires or industrial fires due to the lack of an evacuation plan, so when a fire outbreaks, the occupant is psychologically and physically challenged in a way that makes the individual think irrationally, in which we will identify the appropriate solutions in preparing for an evacuation in case of a fire and how to stay calm.
Introduction
Did you know that when a person is under pressure or in a life or death situation that it particularly impairs their ability to think? Although there are several methods for evacuating a fire in a building the obstacle that challenges most occupants is staying calm under pressure and remembering the evacuation plan. When a fire develops, it creates smoke which is a mixture of tiny particles and gases produced by fire, the particles are mainly of two kinds: Carbonaceous solid particles (soot), producing black smoke and liquid droplets (aerosol mist), which form as some gas molecules cool and condense, producing light colored smoke (Friedman). In the event the occupant is unable to retrieve ...

...but with further research and statistics on evaluating the way individuals respond to fires is an ongoing learning experience that will continue to be a concern. With a growing number of deaths in fire related events it raises the question, do people think rationally or irrationally when a fire outbreaks? Just to think about it, the individual could act in accordance to a fire situation but if the tools needed are not available the person could be left with severe injuries or even death.

Since the early 1980’s Grimwood (2000) has studied and implemented the use of water fog spray directly into the fire gas layers from a fog nozzle, also termed (3-D) water fog, developed by the Swedish Fire service. Grimwood reviews studies and tests conducted by the U.S. Navy. Compared to a straight stream attack using a smooth bore nozzle three significant observations were recorded, the time spent fighting fire was reduced, the working heart rates of the firefighters were reduced, and peak body temperatures of the firefighters were lowered, while implementing the (3-D) water fog technique from a fog nozzle. The author indicates that over the last 10-20 years Line of duty Deaths (LODD) from flashovers, or ignition of the fire gases, in the United States, has increased, while in Sweden there has been a decrease in LODD’s since the uses of fog nozzles was adopted during this same time period. Grimwood evaluates several spe...
In making the decisions to protect people’s lives from hazards and disasters, evacuations sometimes become necessary. Of course early in the reaction to the incident, or the response phase, this may become a decision for local and state emergency managers. The San Diego, California wildfire which occurred in October 2007 caused a large scale evacuation. This essay is an analysis, and identification of lessons learned from the evacuation incident. As well a plan of personal recommendations and improvements will be made based on information covered in the National Housing strategy, and Robert Stafford Act.
Catching Fire: How Coooking Made us Human by Richard Wrangham is a fresh perspective on the evolution of humankind. Wrangham has made a concentrated effort to prove that humans have evolved particular adaptations, like bipedalism, due to the introduction of cooked foods into their diet. In his book, he is legitimately arguing that humans are the way they are because early on in human evolution, early man discovered fire, discovered the joys of cooked foods, and developed all sorts of fascinating traits still being utilized today.
The most pressing issue facing Detroit, in regard to fire, is the steady amount of burning vacant or delipidated buildings, and second to that is the high rate of home fires. For the purposes of this project, the capabilities of
In the case, “Facing a Fire” prepared by Ann Buchholtz, there are several problems and issues to identify in determining if Herman Singer should rebuild the factory due to a fire or retire on his insurance proceeds. I believe that this case is about social reform and self-interest. I think that Singer needs to ask himself, what is in the firm’s best economic interests. There are several things to question within this case, what should Herman Singer do and why, should he rebuild the factory or begin retirement, if he rebuilds, should he relocate the firm to an area where wages are lower and what provisions, if any, should Singer make for his employees as well as for the community?
Fire safety education is a crucial aspect of fire prevention. The general public needs to know how big of a threat fire is to them and how they can do things in their everyday lives to improve their safety, as well as preventing the threat of fire to begin with. The commission also realized that it was critically important that people know how to properly act once a fire has started. It is important that people have the knowledge to act quickly, safely, and effectively. When people don’t understand fire they can react in many negative ways such as panicking, not evacuating effectively, or by trying to fight a fire that they are not going to be able to extinguish. All these human reactions can decrease safety and end with tragic results. In the commission’s report they approximate that nearly 70 percent of all building fires were due to people acting carelessly because they did not understand the fire dangers that were present. The commission cited studies like one conducted in southeast Missouri. In the southeast Missouri community, a huge emphasis was put into public fire safety education because the fire death rate of the community was much higher than the national average. After increasing fire safety education in the community it was no surprise that the rate of deaths and injuries decreased

Not only is a fireman strong mentally, but also physically. Being physically fit is just part of a fireman’s job. For example, cardiac stamina is vital for the fireman since the number one cause of death in firemen on duty is heart attack. The heart undergoes extreme stress when a fireman exerts himself in a burning building. If the fireman’s heart is not conditioned, he is at higher risk for heart attack. Also, rescuing a person from a burning building necessitates a large amount of strength. Often, an individual that has been trapped in a burning building is weak or unconscious from smoke inhalation and must be carried to safety. A fireman must also maintain strength in order to handle heavy equipment such as ladders, car extrication devices, and water hoses. A fireman is strong.

Water fogging and mist systems are suitable for fighting various types of fires. It provided with sensors that works only when the temperature of the room is exceeding the natural levels, where these sensors release the water droplets or fogs in the air at high velocity which cools the surrounding area effectively and hence minimize the expected heat related damage (Bre, 2005).
