Installation Of Sprinklers Research Articles

Perancangan dan Penempatan Alat Pemadam Kebakaran Jenis Sprinkler

The fire suppression ability of this sprinkler installation compared to other fire extinguishing equipment has been proven to be more effective. Because the sprinkler system does not require an operator when operating, fires can be prevented earlier before causing greater losses. For this reason, the implementation of sprinkler systems in buildings is crucial. According to KEPMEN PU NO. 10/KPTS/2000, a building must have elements that can maintain structural stability to a certain level during a fire. This research was conducted directly in the field, and the necessary data was obtained independently through interviews with relevant parties. The author conducted research observations in the archive warehouse to obtain both primary and secondary data. Primary data included field documentation and calculations. Planning calculations were done directly by calculating the number of sprinklers, water requirements, and reservoirs to determine the precise needs. Based on the survey, it was found that the size of the archive warehouse is 48 x 48 m, totaling 2304 m2. The maximum distance between sprinklers used was 4.6 m. Therefore, the effective distance between sprinkler heads is 193 units. The result of the calculation for the water supply for the sprinkler system obtained 34,139.77 liters, with the total overall cost for the equipment and materials used being Rp. 63,121,925.74. Based on the data and calculation results regarding the planning and design of fire protection equipment in open active spaces adhering to the NFPA-13 Standard for the Year 2019, it is expected to provide comfort and safety against the threat of fire incidents.

Mathematical model of the supporting structure of a finely-dispersing sprinkler installation

BACKGROUND: The paper considers the issue of creating a reliable system for protecting fruit plantations from adverse atmospheric phenomena, diseases, pests in mountain terrain, which can be solved with the use of artificial irrigation. To solve this issue, it is necessary to develop a supporting structure for a finely-dispersing sprinkler installation with sprayers attached to it, which make it possible to process fruit plantations from all sides simultaneously. At the same time, the design and technological parameters of the operation of the finely-dispersing sprinkler installation depend on ensuring the strength and stability of the supporting structure.
 AIMS: Development of the mathematical model of the supporting structure of the finely-dispersing sprinkler installation.
 METHODS: The methods of physical and mathematical modeling, the method of task-oriented enumeration of parameters (the Gemerling’s method) were used. The research object is the supporting structure of the finely-dispersing sprinkler installation. The verification of the operability of the supporting structure according to the criteria of strength and stability was carried out with a computer using the MATLAB software.
 RESULTS: An optimization problem has been solved for 4 variants of the layout of the supporting structure of the finely-dispersing sprinkler installation.
 CONCLUSIONS: Various options for the layout of the supporting structure of the finely-dispersing sprinkler installation have been obtained, ensuring the fulfillment of the conditions of stability and strength; technological requirements for the total length of the pipeline, for its internal diameter and for the number of nozzles; the requirements of the standard for the material and outer diameter of the pipeline.

A Study on the Sprinkler Installation Plan in the Air Conditioner Room through TRIZ Analysis

In the last five years, there have been a total of 1,168 fires in outdoor air conditioners, half of which 49.4% occurred in residential facilities. Since 2006, the “Regulations on Housing Construction Standards, etc.” have been revised, and the Air conditioner room that has entered the indoor space is operated without opening the louvers sufficiently in a small space, or dust and moisture accumulate in a poorly ventilated state due to loading a large amount of goods, and if the air conditioner is operated for a long time due to a heat waves, the outdoor unit overheats, increasing the risk of fire. The study investigated the cases of the sprinkler installation in the Air conditioner room by type, and analyzed the three causes of fire suppression failure of the sprinkler in the event of a fire: ignition source, combustible material, and head operation failure, and analyzed using TRIZ technique. In order not to fail to extinguish the fire, An additional head should be installed. Water radiated from Upper head cools the thermal part of Lower head when installed in combination with the Upper and lower head, and the Lower head does not work. When the upper head is operated, the lower head can also be operated, and the fire suppression effect was demonstrated through a fire test.

The Influence of Water Quality Change on the Corrosion Process in Galvanized Pipes of Fire Protection Installations

The article presents the results of an investigation of water composition and quality in sprinkler installations, as well as the influence of temperature changes on the corrosion process. The physical and chemical components of the water were measured to ascertain the influence of its properties on the corrosion process in a wet pipe sprinkler system operating in significantly changing ambient temperature conditions. The article presents the results of measurements of the wall thickness of galvanized pipes and changes in the chemical composition of water occurring under the influence of variable ambient temperature. The range and variability of temperatures corresponded to the seasons of the year: spring and summer in a temperate climate. Changes in the corrosive aggressiveness of water were assessed using the Langelier saturation index (LSI), the Ryznar stability index (RSI), and the general acidity intensity index (I). The tests revealed that the tap water used demonstrated strong corrosive properties for galvanized pipes. The calculated indices showed the tendency of water to cause corrosion (−1.1 > LSI < 1.0; RSI = 7.1–12.8). The chemical parameters that significantly influenced the corrosion of galvanized pipes are chloride (Cl−), sulphate (SO42−), and bicarbonate (HCO3−) ions. An important factor contributing to the intensification of corrosion is the roughness and heterogeneity of the pipe surface.

Exploring relationships between perceived suppression capabilities and resident performance of wildfire mitigations

Increased wildfire activity has led to renewed interest in enhancing local capacity to reduce wildfire risk in residential areas. Local fire departments (LFDs) are often the first responders to rural wildfires. However, LFDs may also struggle to address service demands in the growing wildland urban interface, including increasing numbers of wildfire incidents and changes in area socio-demographics (e.g., aging populations) or culture (e.g., decreasing volunteerism, new residents). We used a mixed-mode survey (n = 770) to explore rural perceptions of various fire service organizations (FSOs), including LFDs, in wildfire-prone areas of northeastern Washington State, USA. We also explore relationships between perceptions of LFD capabilities or capacity (e.g., personnel, LFD ability to respond to private property during a wildfire event) and resident performance of eleven wildfire risk mitigation activities that contribute to home defense (e.g., development of a water supply, installing sprinklers). We found that study participants have relatively high levels of trust in LFD's to respond to a wildfire event on their properties. This trust is also slightly higher than the amount of trust placed in other FSOs (e.g., state, federal, private contractors). Respondents also largely understand that LFDs do not have sufficient capacity or capability to respond when wildfire events impact multiple private properties in their area. Trust in LFDs was significantly and negatively correlated with resident installation of fire-resistant siding, installation of sprinklers on their home, and placing firewood or lumber more than 30 feet (∼9 m) from their dwelling. Similarly, respondents' perceptions of LFD capacity and capabilities was significantly and negatively correlated with purchasing a generator and stacking firewood more than 30 feet (∼9 m) from their home. Our results suggest that perceptions of FSOs have the potential associations with resident performance of select wildfire mitigation actions (e.g., firewood placement, installation of non-flammable siding). However, they also were not significantly related to many other mitigations suggested for residents to complete as part of broader wildfire management strategies (e.g., driveway clearance, water supply establishment, safe zone creation).

545 “After The Fire: Legacy of A College Dormitory Fire Twenty Years Later"

IntroductionIn January 2000 fire erupted at a local college. Panicked students, many who failed to attend school-sponsored fire drills or simply ignored alarms, found themselves scrambling to escape. Seven students were admitted to a burn center (BC) for critical burns, with 54 initially staged in the Medical Center Emergency Department. While this dormitory fire took place more than twenty years ago, its legacy is still being felt today.MethodsHistory shows that, with any tragedy, there are lessons to be learned to lessen the impact on property destruction, injury or death. Looking at the legacy of this fire, four key areas of improvement emerged: disaster preparedness, media relations, legislation and fire prevention.ResultsChanges to disaster preparedness include an expanded, more comprehensive response plan, revised triage and transfer protocols, BC staffing protocols, creation of a regional group of BCs, which eventually morphed into a Disaster Consortium, and a medical command center for regional disaster response. A series of articles resulted in a Pulitzer Prize-finalist book, documenting the journey of two of the survivors, with award-winning photographs displayed at a national museum. Redesigned fire safety programs emphasizing escape plans and the dangers of false alarms now targets high school and college students, an often overlooked group, and clinical education programs have expanded to include nursing’s role in disasters, reinforced with a functional exercise. Two survivors are motivational speakers, continuing to share their personal story on campuses across the United States. New legislation mandated sprinkler installation in dormitories nationwide, and a non-profit foundation was formed to improve burn care. The anniversary of this fire is commemorated annually on campus to serve as a powerful reminder for new generations of students.ConclusionsDespite this dormitory fire being ranked as the deadliest in state history, all these years later the legacy of this landmark event remains one of triumph and resilience, as its impact is still evident today. These lessons serve as the foundation for improved disaster response, locally, regionally and nationally.

Fire safety assessment of sprinkler systems for car parks using the J-value methodology

A J-value assessment was carried out to quantify the costs and benefits of sprinkler system installation in car parks, both with respect to life safety and property protection. Nine scenarios were established based on collected input data. All car park types were considered for the USA, England, Scotland, Wales and the UK nations collectively, while separate considerations were made for multi-storey car parks (MSCPs) in the UK and for MSCPs, underground and other parking types in England.Even when assuming 100% sprinkler effectiveness, the J-values for the nine scenarios were all larger than unity (ranging from 5 to 555), thus indicating that the installation of sprinklers is not a cost-effective investment for car parks from a societal point of view. The analysis showed that different car park types must be treated separately, due to specifics of structure and fire statistics. The lowest J-values were obtained for MSCPs and underground car parks. Sprinkler installation mainly provides property protection benefits, because of property loss savings substantially outweigh those associated with life safety.Even though sprinklers were not cost-effective for car parks in the current analysis, the scarcity of data and new emerging technologies suggests that further investigation is needed.

ДОЖДЕВАЛЬНАЯ МАШИНА «КАСКАД 65Т» ДЛЯ РЕШЕНИЯ ПРОБЛЕМЫ ИМПОРТОЗАМЕЩЕНИЯ В МЕЛИОРАЦИИ

The Russian Federation has been actively establishing import substitution processes since 2014. First of all, this situation is caused by the number of sanctions measures and restrictions applied to the Russian Federation. The essence of import substitution is to replace foreign goods and components by developing domestic production, which is especially important in agriculture, in which about 75% of components and 42% of equipment are imported from abroad. As for the sprinkler equipment fleet, 40% of foreign machines account for it, while the remaining 60% of domestic sprinkler installations are outdated, are operated for a period many times exceeding the standard use and more than 80% of them have 100% wear. The currently available domestic production facilities are not able to meet the existing need to replace existing worn-out sprinkler machines, due to outdated production technology that does not meet the modern needs of agriculture, while imported sprinkler machines have significantly increased in price, and a number of them are no longer available for the Russian market. In this regard, the purpose of the article was to analyze the state of the park of sprinkler equipment in Russia and the Saratov region and substantiate the need to develop the production of modern sprinkler machines of domestic production. To achieve this goal and solve the problem of import substitution in land reclamation, a modern sprinkler machine "Cascade 65T", developed by the staff of the Saratov State Agrarian University named after N. I. Vavilov, is proposed, and its main technical characteristics are presented.

Introduction: Fire cases increase in residential buildings because short circuits, at dormitories are mostly affected by human factors. X university dormitory building is a place for 24 hours of students’ activities with a lot of electricity consumption, bad behavior; overpowering extensions, and many flammable objects such as paper and furniture. Research objectives are to investigate the appropriateness and mapping needs of fire protection systems with regulations. Methods: The research is a semi quantitative analysis. Primary data is conducted with observations by using a checklist form that refers to the regulations and results of managers' interviews. The obtained data are categorized into good with suitability >79-100%, moderate ≥60%-79% and poor <60%. Result: The appropriateness of the active fire protection system is under 60% or in the poor category. The appropriateness of the fire extinguisher is 47.77%, the hydrant is 58.75%, the alarm is 18.75% and the heat detector is 35.90%. There is no sprinkler installation in the dormitory building and no commitment from the top management regarding occupational safety and health. Fire extinguisher’s need is 10 tubes per floor, the number of hydrants have been fulfilled, alarm requires an additional 1 unit on each floor and a heat detector requires a total of 114 units. Conclusion: The active fire protection system is still under 60% (poor category) and no maintenances. Based on the aforementioned mapping results, it needs to add the number of piece equipment according to the regulations and maintenance efforts.Keywords: active fire protection system, dormitory, mapping

563 “After the Fire”; The Legacy of a College Dormitory Fire Twenty Years Later

Abstract Introduction In January 2000 fire erupted at a local college. Panicked students, many who failed to attend school-sponsored fire drills or ignored the alarms that night, found themselves scrambling to escape. Seven students were admitted for severe burns to a near-by burn center (BC), with 54 initially staged in the Emergency Department. While this dormitory fire took place more than twenty years ago, its legacy is still being felt today. Methods History shows that, with any tragedy, there are lessons to learn that lessen the impact of property destruction, injury or death. Literature review of several major fires looked at their impact promoting burn care and fire safety to correlate those lessons with this fire. Four key areas of improvement emerged: disaster preparedness, media relations, legislation, and fire prevention. Results Changes to BC disaster preparedness included formation of a more comprehensive plan, revisions to triage and transfer protocols, new guidelines for unit staffing, creation of a mid-Atlantic group of BCs that eventually morphed into the Eastern Regional Burn Disaster Consortium, and installation of a medical command center for regional disaster response. Media relations saw a collaboration with law enforcement, due to criminal investigation, and a partnership with a syndicated newspaper to document the journey of two survivors. A series of articles eventually resulted in a Pulitzer Prize-finalist book, with award winning photographs displayed at a national museum. Redesigned fire safety programs targeted high school and college students emphasizing escape plans, and clinical education included disaster drills. Two survivors became motivational speakers, sharing their personal story on campuses across the United States. New legislation mandated sprinkler installation in dormitories nationwide, and a non-profit foundation was formed to improve burn care. The anniversary of this fire is still commemorated each year with a ceremony and wreath-laying on campus. Conclusions Despite this dormitory fire being ranked as the deadliest in state history, all these years later the legacy of this landmark event remains one of triumph and resilience as its lessons still to resonate today

Modeling of the scheme of location of active raining equipment of the closed irrigation system

The purpose of the study is to develop a procedure for determining the parameters of the layout of active sprinkler equipment in closed irrigation systems. This paper presents the importance of transforming agricultural production into a highly developed sector of the economy which is impossible without reducing its dependence on adverse climatic conditions. The introduction of modern computer-integrated technologies, including precision farming, due to the need for economic use of visible and energy resources, is considered. Closed irrigation systems with the use of reclamation equipment such as universal sprinklers have become widespread. The existing fleet of efficient sprinklers will consist of 64% of frigate sprinklers. The article considers a complex of sprinklers, which will consist of eight irrigation fields, the total number of sprinklers in the system is eight. The article discusses in detail the principle of operation of the presented closed irrigation system, namely the system of water supply pipelines to sprinklers, and equipment that controls the operation of this system, such as booster pumps, hydrants, transformers, valves, communication lines. The article considers the process of calculating the total number of options for connecting sprinklers. In the considered system 4 sprinkler installations which are connected and disconnected in pairs can be in work at the same time.

Проблема защиты высокостеллажных складов спринклерными автоматическими установками пожаротушения

Рассмотрены вопросы обнаружения и тушения пожара при высокостеллажном складировании продукции, являющейся пожарной нагрузкой, с использованием пожарных извещателей и автоматических установок пожаротушения (АУП). Проанализированы различные схемы АУП и подачи огнетушащих веществ (ОТВ), их преимущества и недостатки. Исходя из особенностей пожара на стеллажных складах, показана необходимость скорейшего его обнаружения и подачи ОТВ. Сформулированы задачи, решение которых позволит добиться максимальной эффективности применения АУП на высокостеллажных складах.Currently, there is a tendency to equip objects (warehouses, shopping centers) with racks for storing various products. The stored products represent a significant fire load (combustible packaging, products themselves, etc.). Racks can be of a great height (more than 10 m), be located both in isolation and in groups, and even be load-bearing as a part of the power frame of the building. The technology of racks loading and unloading provides for the use of electric cars with special lifts (stacker). The result of a fire at an object with high-rack storage (HRS) is a large material damage due to the destruction of stored products and damage (collapse) of the building as well as risk to people and undesirable socio-psychological resonance. Due to rapid flame spread on a vertical in case of fire on the object with HRS, the most important condition for the effective use of automatic fire extinguishing systems is to minimize the time both of fire detection and of commencement of extinguishing agent supply by appropriate sprinklers. It can be achieved by means: a) of special heat-accumulating screens above the racks at a large distance from the top of the stored goods to the ceiling that ensure the speedy operation of heat detectors; b) of satellite detectors which provide a compulsory start-up of the sprinklers. For the purpose of selective operation each satellite fire detector is equipped with a deflector or diaphragm so that the field of view of the detector agrees with the irrigated area. To concentrate the fire extinguishing agent supply directly to the high-rise rack and to provide increased irrigation intensity at the border of the sprayed stream, the spray angle of the sprinkler is limited by the flow shaper. Most often, the sprayed water flow is supplied to the upper tier of the rack and its side surface. Thus, this article presents the features of effective fire fighting at objects with HRS of products that are a fire load at an early stage of fire ignition. Various schemes of automatic fire extinguishing systems and their start-up are analyzed. In the future, it is necessary to carry out a calculated justification of the sprinkler installation sites to ensure the fire extinguishing agent supply both to the upper part and side surface of the burning rack as well as to protect neighbour racks and building structures.

Estimation of wind drift and evaporation losses in sprinkler irrigation of urban green spaces

The wind drift and evaporation losses (WDEL) are high in arid, semi-arid and windward areas, and reduce the efficiency of the sprinkler irrigation system; therefore, this study was carried out in order to achieve a practical criterion and provide a relationship for accurate estimation of the wind drift and evaporation losses in different atmospheric conditions. The experiments were done at the Meteorological Station of the Faculty of Agriculture of Ferdowsi University of Mashhad using a line-source sprinkler irrigation system based on the single sprinkler installation method. To achieve the objectives of this plan, factorial experiment was performed on PGP sprinkler with regard to the two factors, the pressure of the sprinkler function (with three levels 1.6, 2.5 and 3.4 bar) and the diameter of the nozzle (with three levels of 4, 5 and 6 mm) with three replications (morning, noon and night). Assessing the result of the data variance analysis showed that the effects of pressure, aperture diameter, and time on the wind drift and evaporation losses are not significant. Investigating the main effects of these factors showed that the effect of aperture diameter on irrigation losses is significant at the level of the 1%. In order to further investigate, the comparison of mean losses data in three aperture diameter was done using Duncan′s test. The results indicated that aperture 4 with the losses of 44% had a significant difference with other diameters. This result suggests an increase in losses for smaller diameters due to the small droplets and the increase in wind drift. Also, the comparison of the mean losses data in three times showed that irrigation at noon with the losses of 44% had a significant difference compared to other times due to a significant increase in temperature and radiation of the sun and saturation vapor pressure deficit, and there is no significant difference between morning and evening irrigation. Also, analysis of variance showed that the effect of water pressure change between 1.6 and 4.3 bar does not have a significant effect on the WDEL in this sprinkler. In general, the results showed that increasing wind speed increases the losses of evaporation and wind. Also, this study suggested that changing the irrigation time in areas with hot and dry days, from day to night in summer, leads to a significant reduction of the wind drift and evaporation losses.

The J-Value and Its Role in Evaluating Investments in Fire Safety Schemes

Fire safety engineers endeavour to ensure that a design achieves an adequate level of fire safety. For uncommon buildings, adequate safety cannot be based on precedent and an explicit evaluation of the adequacy of proposed safety features may be required. Commonly, this requires demonstration that the residual risk associated with the design is as low as is reasonably practicable. In those situations, a measure for a safety scheme’s benefit relative to its cost is required, as more efficient safety schemes should be preferred over less efficient ones to maximize the number of lives saved under societal resource constraints. To this end, the J-value has been introduced in other engineering fields as a decision support indicator for assessing the efficacy of safety features. The J-value has been derived from societal welfare considerations (the Life Quality Index) and is adopted in the current paper for applications in fire safety engineering. It is demonstrated herein how the J-value can inform decisions on fire safety, and how it can provide a basis for assessing whether or not a proposed fire safety scheme should be implemented. Future work will focus on its implementation as a tool for assessing the benefit of real life fire safety scheme implementations, such as sprinkler installations.

Effect of microclimatological changes on dairy cattle productionunder the coastal climate of Goa

It was observed that in Deoni and Cross bred cow daily change of relative humidity, maximum temperature and minimum temperatures had significant (P < 0.01) effect on daily milk yield of cow. It was inferred that the effect was more pronounced on cross bred cows than that of Deoni and Sahiwal cows. Between the two indigenous cows effect of micro climatological changes was more pronounced on Deoni breed than Sahiwal breed of cow. It was also observed that overall daily milk yield was reduced by 1 g (P > 0.05), 6 g (P > 0.05), 22 g (P > 0.05) and 78 g (P < 0.01) per unit increase of air temperature, relative humidity, temperature humidity index and maximum temperature respectively while data were analyzed as a whole considering all the cows of all the breeds together. Economic losses resulting from temperature-induced reductions in production may justify mitigation of these temperature increases through changes in management practices such as installation of sprinklers in sheds, evaporative cooling of barns, feeding and nutritional strategies, and/or selection of more heat-tolerant animals. So, risk management, by considering perceived thermal challenges, then assessing the potential consequences and acting accordingly, will reduce the impact of such challenges.

Changes in landscape composition of differently irrigated hay meadows in an arid mountain region

AbstractQuestionsDoes the recent change from traditional to sprinkler irrigation result in alterations in the surrounding landscape of species‐rich hay meadows in an arid Swiss mountain region? Are landscape composition and landscape heterogeneity important determinants of plant diversity in these meadows?LocationSouthwestern Switzerland.MethodsWe surveyed vascular plant species in six traditionally and six sprinkler‐irrigated hay meadows. Plant species were divided into grassland specialists and generalists. Individual landscape traits were assessed in circular areas with radii of 50 and 100 m around each meadow in a field survey. Aerial photographs were used to measure the percentage area covered by different habitat types in the present and prior to the installation of sprinklers at the same spatial scale as in the field surveys. The potential effects of irrigation technique and present‐day landscape features on the plant diversity and species composition of hay meadows were examined with GLM and NMDS.ResultsLandscape composition was more diverse for traditionally than for sprinkler‐irrigated meadows, but did not differ prior to the installation of sprinklers. Total plant species richness and the number of specialists were negatively affected by the distance to the closest haystack. Generalists were positively influenced by a variety of different small‐scale landscape traits in the surroundings, whereas the percentage area covered by woodland had a negative effect. Finally, hay meadows irrigated with sprinklers had an increased number of generalist plant species.ConclusionsThis study showed that the small‐scale surroundings, and to some extent the type of irrigation, are important for the conservation of plant diversity of these meadows. Furthermore, the study suggests that the installation of sprinklers was associated with a homogenization of the landscape, which facilitates land use. Extensive management should be promoted by compensation payments for farmers to prevent intensification.
