The automatic fire sprinkler system was one of the earliest sprinkler systems placed into effect. The origin of the modern day automatic sprinkler system dates back to the early 1800’s. The first automatic sprinkler system was created in England in the 1806 by John Carey. It consisted of a pipe with valves held closed by counterweights attached by string. When flames burned through the string the counterweight dropped to the floor, which opened the valve that released the water and extinguished the fire. As the 1800’s progressed, the basic pipe system for sprinklers was becoming more prevalent across England. It began to pop up in textile mills all through out the country. In 1864, as sprinkler system use grew, Major Stewart Harrison of the 1st Engineer (London) Volunteers invented the first automatic sprinkler head. A few years later two gentlemen by the names of Henry Parmelee of Newhaven, Connecticut, and Frederick Grinnell of Providence, Rhode Island, added to the sprinkler head to give it a more practical application. Parmelee took the automatic sprinkler head and added to it a fusible link that broke at about 160oF. This allowed the system to control which heads broke so the whole system wouldn’t drown the whole structure in water, it would only release where there was sufficient heat to break a head. Grinnell invented a head that could withstand higher water pressures without break as well as distribute water more evenly. Each of these inventions increased the efficiency of the systems greatly. Now in today’s modern fire protection era, automatic sprinkler systems are used to protect everyday buildings around the world. It is most commonly in commercial use buildings. This includes but is not limited to schools, hospitals, ... ... middle of paper ... ...dards and codes such as the NFPA or OSHA’s codes and standards. The automatic sprinkler system is the oldest and most widely utilized system in effect today. Through simple application of water onto a fire before it can grow it has saved countless lives and saved countless amounts of money in property and business. As its use grows in the commercial setting, it has also begun to grow in the residential setting. There are few areas that require automatic sprinkler systems in residential homes, but as they are proven to be safe, affordable, and effective, this will rapidly change. It will not be long before there is an automatic sprinkler system in every business as well as home.

Thousands upon thousands of acres are lost in forest fires every year. We always hear about the dramatic losses caused by forest fires and are often concerned by them. There are so many horrible effects from fires and most of them affect so many people. Studies have shown that out of all of the different methods to decrease fire damage, prescribed burns are the most affective. Many people would argue that they are not as affective because they cause so many health problems. Although that is a very important view and may seem valid, those health issues are not as extreme as one might think. People should look at the majority of the benefits form prescribed burns and they will see how affective and important they are. Prevention is the key to society these days and is definitely an important factor in saving lives. If more lives can be saved as well as land and wildlife, prescribed burns may be the better way to go about forest fires. Although, prescribed burns are better for the environment in order to prevent drastic forest fires, severe damage to timber and extreme death of wildlife; some people feel it affects the health of a firefighter too much and it causes too many long term effects.

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
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
...pectors had determined that the reason on which the fire had rapidly spread was due to many structural and design flaws. Wires not being grounded correctly, a fire alarm that never rung or let out a peep. The stairwell which was a critical escape path overwhelmed by smoke. Other defects located in the air conditioning systems, all which helped the smoke spread. Despite of 83 building code violations, no one was ever punished for the lives that were lost. Later, the Hotel was being rebuilt, and the fire marshal had issued for the hotel to pay 192000$ to install sprinklers in the casino room; the clark county building official had rejected for the fire marshal’s charge. Authorities then had said that the automatic sprinkler systems were better off installed in the first place, as they could have prevented the loss many lives and the disaster at the hotel. Even after
Automation is a step beyond mechanization, Automation is the use of control systems and information technologies to reduce the need for human work in production of goods and services. Where mechanization provided human operators with machinery to assist them with the muscular requirements of work, automation greatly decreases the need for human sensory and mental requirements as well. Automation plays an increasingly important role in the world economy and in daily life. Automatic systems are being preferred over manual system. Through this project we have tried to show automatic control of a house as a result of which power is saved to some extent. The Global System for Mobile Communications
...ve less of the luxury features, but still provide the basic functionality of a Quartz product, with steady pressure, consistent temperature, and made of sturdy materials that will not break after short use. Dropping the price of the Quartz system, or introducing a lower cost system, could initially decrease profits for Aqualisa, but with a product at a lower cost, it could compete with the current unreliable systems on the market. However, once the do-it-yourselfer and plumbers start to use the system, they will have users hooked, and potentially raise its market share. Also with the prospect of more satisfied customers and plumbers, brings the benefit of “word of mouth” advertisement, users will start demanding it from plumbers and builders, and the potential of users who may splurge for the better luxury systems, because they now know and trust the Aqualisa brand.
Since the inception of pressurized systems to produce and transmit energy, it has been a constant goal to find safe, dependable means of relieving pressure. The simple, inexpensive, spring loaded relief valves has been manufactured for over a hundred and fifty years, performing its job with varying degrees of reliability over that time period.
This 80,000 pound powerhouse was just purchased by the Swarthmore Fire & Protective Association. Equipped with a 100-foot aerial and a 2000 gallon per minute (gpm) Hale single stage pump, Tower 14 can knock down just about any fire.
In the area of the firemen¡¦s own personal protective equipment, it too has be advanced because of computers. Twenty-five years ago, the turnout gear worn by firefighters was used to keep the firefighter from getting wet mainly then with the introduction of Nomex, which was a self-extinguishing man-made material, then came Gortex and PBI.

Peoples are always trying different techniques to beat the scorching heat, specifically in summer season. Recently, there many methods that proved their quality in reducing the atmospheric temperature to the required rates. There are three main types of evaporative cooling systems which are sprinkler systems, pad systems and Fogger systems. This project interested in the last one. Fogger system is defined as a type of nozzles that sprays water with high-pressure (up to 200 psi) or low pressure (less than 50 psi) to the air as a fine fog or mist. These fine fog or mist evaporates into the outdoor air in order to cool this air which is located beside the fogger (Giacomelli, 2003).
Communication is essential in education, training and everyday life. It's a means by which a thought is transferred from one person to another. Effective communication occurs when the intended meaning of the source and the perceived meaning of the receiver are virtually the same, Schemerhorn (2005).
The next statute that must be met is the piping needs to be protected from freezing and corrosion from the surrounding environment. This assures that if a fire occurs the piping will be able to take the water pressure that is flowing through to the sprinkler system. Also it calls for the system to have a proper drainage system that allows the system to drop the water from the sprinkler system and then have it drain back into a reservoir. The final statute from OSHA 1910.159 is that the sprinklers be space...
The article evaluates the efficiency, effectiveness, social, economic and environmental impacts of the drip irrigation system. The drip irrigation system has the potential to increase the agricultural productivity and also to reduce water usage required for irrigation. It is a system of pipes and tubing located under the soil. Water is passed through these pipes which end at near the roots of the plants. This makes the water loss minimal. Initial stage is designing the system and its installation follows it. The article states the advantages and disadvantages of the system and also cites evidence with regard to the social, economic and environmental aspects.
