The United States has a serious and substantial fire problem. Roughly once every one and one half seconds an unreported fire occurs. Nearly once every minute somewhere in America there is a home fire serious enough to warrant calling the fire department. Smoke detectors can detect a fire early on so firefighters have more time to attack the fire and save the dwelling. A smoke detector can potentially save lives. There are many different aspects of smoke detectors in this paper I will discuss many of them. Theory of Smoke Detectors. A smoke detector is a device used in homes and other buildings to warn people of smoke or a fire. It makes a loud buzzing noise within seconds after smoke enters it through special vents. There are two kinds of smoke detectors, ionization detectors, and photoelectric detectors. . History of Smoke Detectors. In the 1960s the average U.S. citizen had never heard of smoke detectors. By 1993, an estimated 92 percent of all American homes, single and multi-family apartments, houses, and dormitories were equipped with detectors. In the mid 1980s smoke detector laws, requiring that detectors be placed in all new and existing residents, existed in 38 states nationwide. Smoke detector previsions have been adopted by all of the model building code organizations. The National Fire Alarm Code requires a minimum of one smoke detector on every level of the home and outside each sleeping area. In newly constructed homes, the code now requires all hardwired smoke detectors to be interconnected, so that if one smoke detector is activated, all smoke detectors in the house will sound the alarm. New homes are also required to have a smoke detector installed inside each room used for sleeping. (Webster's International Encyclopedia) . Impact of Smoke Detectors. Fire services across the county have played major and influential public education role in alerting the public to the benefits of smoke detectors.

4. Glenn T. Seaborg and Trans-Uranium Elements
His discovery of the element Americium allowed for an improved version of the smoke detector (World Nuclear Association, 2010). Smoke alarms work by ionizing the air around the detector with Americium, completing the circuit and preventing the alarm to go off. When smoke disrupts the air and pushes its away from the detector, it breaks the circuit and trips the alarm. This was an improvement over optical fire detectors which were much more prone to false alarms. ...

Essay about Code Changes After the Mgm Grand Fire
At the time of the MGM Grand Fire, it was not required that fire department personnel had to be part of the building construction plan review process. The fire department is now largely involved in the construction and plan review process before a building is built. Also, construction materials used are more fire resistant. Ventilation systems have also been improved, and are very helpful in removing the smoke, rather than allowing it to make its way to upper floors of a high rise structure, which was a large cause of loss of life in the MGM Grand fire due to smoke inhalation and carbon monoxide poisoning.

Another strategy could be offering the new customers who opt for an automatic payment service a fixed price for the first three years (not increased by the annual 3% rate). In this case the LTV net of the acquisition costs would be $1305,5, still higher than the one the company would earn whether the customer opts for a not automatic payment. Moreover, offering 8 years of fixed price ($480) is still more profitable than the case in which the chose a not autopay method, but it is, in my opinion, not recommendable, because of the negative effect that it could have on the customer that chose this option before. Indeed they could decide to resign the contract and try to get a new one with the more convenient conditions. (Table 2)
Needs Assessment And Recommendations To The Baltimore County Fire Department
Many department, including BCoFD, are looking for different solutions to help fix this tissue. The goal of this research project is to conduct a needs assessment and provide recommendations to the Baltimore County Fire Department for an outline of a curriculum for a CP course based off the findings of the needs assessment. Extant data was collected by using inclusion and exclusion criteria requirements in the data collection tools from both ImageTrend and National Fire Incident Reporting System (NFRIS) for non-emergency calls. In 2014, BCoFD initiated a specific policy for non-emergency responses that was collected through EMED reports in ImageTrend. During that year, the number of Non-Emergency Responses came to 8,590. In 2016, non-emergency responses came to a total of 12,102, almost 3,500 calls more from 2014. As of March 30th, 2017, the total non-emergency call responses were at 3,615 and continuing to grow. Not only non-emergency calls are climbing, but the total call volume for BCoFD is increasing more and more each year. Since 2013, there has been an average of 5,705 increase calls each
Firefighter Safety Essay
Today’s building construction also lends itself into the deaths of firefighters. We see everyday about building collapsing in on our guys while they are fighting fire. The builders and engineers are always coming up with lighter materials and cheaper ways to make things to save them money on construction to boost their bottom lines with out due regard for safety to others especially firefighters. A light weight wood frame truss will fail under fire conditions in a little as five to eight minutes. Given the time that the fire is discovered and called into dispatch, the time they have to turn the call around and dispatch units, one minute to get enroute, and if they can get on scene within five minutes, another couple of minutes to pull hose lines and enter the building, your are on the threshold of a roof collapse. Then we also put guys on the roof to ventilate thus weakening the roof even more. All this for a house that the insurance company is going to tear down anyway and

For years if not decades, firefighters have responded to a reported structure fire that turned out to be a fully involved single room. This fire scenario requires a core set of fire tactics and skills to control and extinguished the fire, but is it this simple? Perhaps twenty years it may have been, but new dangers are lurking in every scenario and may have detrimental outcomes for unsuspecting and unaware firefighters and victims.

This research is providing firefighters with new information about how and why
Legacy Fire Research Paper
Many fire service personnel that have fifteen or twenty years of service have seem many things change over time. One radical change is the way fires consume structures today when compared structures years ago, these fires have be classified as modern and legacy fires. When responding to a modern construction fire versus a legacy fire, does it change how we fight these fires? Well the answer to that is simply yes! Modern construction physiognomies have greatly changed to accommodate the comfort of the homeowner, which is not firefighter friendly. In modern construction home the floor plans are larger in size to give more living space. As the living spaces grow the footprint of the residence increases as well. As the word modern leads to occupants thinking comfort, when truthfully causes disadvantageous consequences for the fire service with open geometrics, new construction materials, and also include an increased fire load. All these construction advantages only lead to faster propagation of the fire, as well decreases the amount of time for a flashover to occur. Modern construction has led to hasty changes in fire dynamics, which at the same time decreases the amount of time to escape to safety. The structural collapse time is greater since the amount of time as been lessened
Types Of Construction Of Firefighters
Within the United States there are five different types of construction. Firefighters need to know and understand each of them. Every construction type have fire resistant weaknesses, these weaknesses will result in fire spreading in the building. If firefighters understand how the fire will spread, then understand how to extinguish the fire faster and more importantly firefighters are better protected from injuries or worse. In America all buildings are associated with one of the types of construction, identified by Roman number. The building codes are, fire resistant (type I), combustible (type II), ordinary construction (type III), heavy-timber construction (type IV) and wood-frame construction (type V). It is important to remember that all buildings are not the same. Each different building construction type will burn much differently than the others do. In order to be able to size-up a building 's fire hazard, firefighters need to be able to understand a buildings contents and construction. Materials that are stored inside of the building and also materials used to construct the building will both fuel the fire. Also know that if a structure is vacant or if the contents in the building are not combustible, the main fire hazard is the building. The scale of the construction types are scaled according to the fire load of combustible material that was used for its construction. A fire resistant building is constructed with least amount of combustible materials, and a

Thousands of fires occur on a yearly basis throughout the United States. Whether it is forest fires, house fires, or any other event that involves uncontrollable flames, the outcome will always be the same; high amounts of destruction and physical damage. When fire emergencies occur, responding to the incident may not be much of a complication as apposed to determining the source from where the fire started or what triggered its behavior, which is truly the challenge. In order to do so, a fire investigator has to be present at the scene of the fire after it has been eliminated. The investigator, after reviewing any possible marks or behavior trails, will conclude if the incident was indeed an accident or intentional, thus making it an act

Research Paper On The Triangle Shirtwaist Factory Fire
The Triangle Shirtwaist Factory Fire’s Role in Women’s Suffrage Fire swept through the eighth floor of the Asch Building at 4:40 P.M. on Saturday, March 25, 1911. Five minutes later, the fire alarm was pulled down the street, and firefighters arrived at the scene just two minutes later. By 4:57, the fire was over, and one hundred forty-six people had died. In those seventeen minutes, panic ensued as six hundred workers on the eighth, ninth, and tenth floors rushed to escape. This was incredibly difficult since the rooms were crowded with equipment, the floors were littered with piles of fabric, and the air was filled with lint.

Native Americans in pop culture have been very misunderstood in many ways. The stereotypical Indian that lives on a reservation doesn’t look like he lives in the 1600s. Indians have evolved to fit more into pop culture, but this isn’t always the case. For example, in a movie called “Smoke Signals” a boy named Victor and Thomas set out on a journey of self-discovery and they head all the way from their Indian reservation to Phoenix Arizona. Indians have an easy way to pass down old tradition to the newer generations that follow behind.

Pros And Cons Of Residential Fire Sprinklers
Home builders associations not only in the Richmond area, but even in other countries are strongly opposed to making residential fire sprinklers mandatory in new housing development. Construction companies are arguing that the materials they are using are fire resistive, and smoke detectors are now wired right in with your electrical system making them more reliable (Jeffery, 2008, para. 31). While these measures taken by builders certainly are a step in the right direction, they simply are not the final destination. Jeffery (2008) further explained that CTV News a local news station in the Ontario area, reported on a story involving children aging from 5 to adolescent, and their response to smoke detectors. The children understood that the smoke alarm would be activated, as well as what they were to do once they heard the alarm, however, when the alarm sounded not a single child got out of bed (para. 22).

Persuasive Essay On Electronic Cigarettes
Electronic cigarettes were first introduced into the tobacco market in 2003. However, in the last few years, electronic cigarettes have been trending, especially among high school students. According to the Surgeon General study, “In 2015, 1 in 6 high school students reported using e-cigarettes in the last month”. The promotion and production of electronic cigarettes is an issue that must be addressed because they are attracting minors who may have never been addicted to nicotine prior to the introduction of e-cigarettes in the market. Companies have branded e-cigarettes as a ‘safer’ alternative to regular cigarettes, however, it is quite possible that consumers, more specifically the youth, are not well informed of the ingredients in them.

Also called a smoke alarm is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible or visual alarm from the detector itself. Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery.…

Smoke Alarm “Smart Smoke Detector” Report
Introduction and background, project plan.
It is usually very traumatising for homeowners in the event of house fires. Loss of property and life are the most likely outcomes associated with house fires. This situation is worsened if the homeowner is not insured or his insurance policy is limited to specific fire damages and causes.
In Australia, due to the high prevalence of bushfires, high quality smoke detectors have become an essential part and a compulsory fitting of every household in the country. This is necessary measure adopted to ensure safety of the occupants, and to minimize damages in case of house fires.
A typical smoke detector is designed to intersect smoke particles. When smoke particles interfere with the path of light to the sensor, the sensor circuit sequential sets up an alarm irrespective of what caused the smoke. Thus, smoke emanating from cooking or incense stick could set off the alarm. This makes it quite difficult to distinguish between false or actual alarms. As a result, this can contribute to alarm assumptions, which may lead to great damages in cases of fire.
What if there was a product that could overcome these issues and simply did the job it was intended to do, making it useful and less annoying? Our Smart Smoke Detector has been designed and built to satisfy the needs and requirements of a typical residential household. According to the National Fire Protection Agency, a well-chosen and working smoke detector will increase the chances of surviving a fire. This is because in case of a fire out break alarm goes on its occupants may have at most 2 minutes to evacuate.
Smart Smoke detectors will allow customers to evade the smoke detector and to reduce the annoyance of the alarm. The alarm will still sound only this time by the use of a heat detector, sensitizing the homeowner of a potential fire problem. Approximately after 1 hour, a squeak will sound alerting the user that the smoke detector is being re-activated.
Moreover, we will also have a peep to alert the user that the backup battery level is low. This report examines extensively and pinpoints the expected process that Global Engineering will follow to achieve a working prototype of the smart smoke detector.
The goal of this project is to assemble a Smart Smoke Detector with a smoke detour system. This will be a more inventive and improved adaptation of the conventional smoke detectors obtainable in the market. The main objectives are for this project are to be completed in time successfully and the final product to be marketable globally.
In order for success to be realized, the team must take into account every aspect extensively to reduce possible failure risks. Consequently, it is crucial for the team to come up with a comprehensive project plan that will take into considerations all the project risks as well as the project completion timeline. This prior planning will ensure that the product is built in an efficient and effective manner enhancing its marketability.
Global Engineering outlined the tasks necessary to build the final product while formulating the project plan. This project plan outlined the expected duration of the tasks n which Global Engineering could achieve optimum results. We used Gantt charts in our planning to facilitate the visual display and relationships of these tasks and their timings. Through Gantt chart predetermined project tasks timeline we could schedule resources and staff workloads as efficiently as possible.
There are diverse requirements for every task; some tasks need others to be completed before they could be started, while others require employment of a specific knowledge and skill to achieve the complete it, etc. The team defined the project tasks based on various factors and concerns of technical and financial matters.
It is most crucial in planning the project to make sure that the end product is priced appropriately, marketable and acceptable by the community. These concerns are enumerated below:
- Conducting market survey to ascertain whether or not the there is a demand for the product in the community. It is worthy to obtain feedback from current smoke detector users and firms selling smoke detectors. This survey will assist in setting a standard product cost and ascertaining how much people are capable and willing to pay for this product once they are mounted in their homes.
- In estimating market price for the new Smart Smoke Detector, Global Engineering will have to form a cost budget for construction of the product. Consequently, comprehensive product architecture required to be studied; the study will involve the varying of individual components on both cost and performance basis.
- Constructing, trying and validating the prototype to ensure that all of the product specifications are met and obtainable. This is conducted so as any fallacies and inadequacies in the prototype can be fixed before the production stage, and to confirm that the Smart Smoke Detector adheres to current safety standards.
- Developing a marketing and sales strategy which will deal with product promotion, advertising and preparation such as producing banners, brochures and setting up a booth for Trade Fairs.
Global Engineering convenes every week to keep members informed on the progress of the project. This meeting also gives the chance to all team members to communicate project concerns and search for support and guidance from other colleagues. In addition, it will assist in identifying any unforeseen risks, hence allowing the team to make decisions and implement action plans to mitigate delays which may arise. These meetings will also operate as a support system for the team to attain its goal and ensure a quality product is created.
Budgets are very important while undertaking any project and usually determine its success. Budgets usually involve higher estimates than actual costs in order to cushion against any uncertainties or miscellaneous costs such as labour and materials fluctuations.
These unforeseen problems can be caused by inadequate research during the initial concept development and architectural design and research stage of the project. In addition, there may be disagreements among members and may result project delays and additional expenses i.e. salaries and rentals on usage of labs which result to variances in the budget.
There are a number of methods to combat such uncertainties which is inclusive of costs cutting wherever possible during the early stages of a project. Secondly, carrying out extensive research to avoid testing failures, i.e. a certain component might not work, or the circuit as a whole might not work the way it was expected. This will enhance thorough product knowledge prior to the commencement and agreement among members. Consequently, these measures will ensure timely completion of the project within the budget.

In all honesty I can say I have thought about this particular question too much in my 17 years of being alive, but maybe that's just because I am a huge Marvel fan.

Smoke Detectors In The United Term Paper
The results of NFPA's 10-year study form 1981 to 1990 announced in June 1992 showed that the death rate for individuals in a fire reduced by 42% in those areas where a smoke alarm was available. The tendency to ever more strict smoke alarm conditions is ongoing as more governmental body implement legislation and as legislation ever more includes readily available as well as new homes and directs more smoke alarms per residence. (the Impact of Smoke Alarms) Fire services throughout the nation have performed a foremost and dominant public education function in preparing the public to the advantages of smoke alarms. One more crucial issue in this big and quick diffusion of both the marketplace and the builder community has been the growth and promotion of low cost alarms by commercial companies. In the beginning of the 1970's, the cost of shielding a three bedroom home with competently established alarms was approximately $l000; nowadays the cost of owner-installed alarms in the same house has dropped to as small as $10 per alarm, or less than $50 for the complete home. This cost composition, mingled with efficient public education including main private-public partnerships, has produced a big percentage of U.S. consumers, whether they are leasing or purchasing, to insist smoke alarm safety. (the Impact of Smoke Alarms) Additionally, regional building associations, which bring out model codes such as the Uniform Building Code, the national Building Code and the One and Two Family Dwelling Code for latest and already available homes, have passed guidelines by and large suggesting that smoke alarms be fitted in or near all sleeping rooms and/or on all levels. A legislation insisting all single-station ionization-type smoke alarms bought in the state are to be fitted with 10-year batteries was implemented for the first time by Oregon in June 1999. A 10-year smoke alarm bill has been presented during the 2001 legislative session in New York. Pennsylvania, New Hampshire and Florida are anticipating equivalent bills in 2001. Many national and international fire safety institutes have voiced their support for better fire safety programs together with legislation for 10-year smoke alarms. These comprise of the International Fire Marshals Association, the U.S. Fire Administration, the National Association of State Fire Marshals, and the Centers for Disease Control and the International Fire Chiefs Association. (Smoke Detectors & Fire Alarms) In most of the retail stores a smoke detector can be bought for prices ranging from $5 to $20. A good performance is given by both battery operated as well current used smoke detectors. It is important to make certain that a nationally recognized testing laboratory has tested the purchased product. There should be a minimum of one detector in every floor but for the loft, if the loft space is used for sleeping. When there are extra detectors, it will improve the possibility of early detection. The smoke detectors must be kept in the bedroom either on the wall or on the ceiling at 6 to 12 inches away from the wall or 6-12 inches below the ceiling. This helps the detector in feeling the smoke when it comes near the sleeping area. The detectors that are battery operated can be at once fixed to the ceiling or wall. Electric detectors with wires are a bit hard to fit and require an electrician. (Smoke Detectors save Lives) The alarm will sound before the strength of smoke attains a risky level, or before the fire turns out to be too intense. Smoke detectors also vary by power source. In battery-operated smoke detectors, the batteries last about one year. As the battery starts losing power, which indicates a requirement for replacement, the detector will start giving out 'beeps' once in a minute. Some will prolong this for a week or more. Smoke detectors that function on household electric current, work as long as there is current in the circuit to which they are connected. They are, thus, susceptible to power failure. Plug-in units must be positioned next to an electric outlet where they will not be unplugged or switched off by a wall switch. (Smoke Detectors for Your Home) They should not obtain their power from a remote plug by means of an extension cord. Always use the hold-in clips to avert unintentional plug removal from the outlet. Nowadays, a number of novel characteristics are present in smoke detectors. These comprise detectors…
