Sprinkler Fitting
Sprinkler fitting is a skilled trade that consists of assembling, installing, testing, repairing, inspecting, and certifying automatic fire suppression systems and their associated piping in commercial, industrial and residential buildings. Sprinkler systems installed by sprinkler fitters can include the underground supply as well as integrated systems and standpipes. The fire suppression piping may contain water, air (in a dry system), antifreeze, gas or chemicals as in a hood system, or a mixture producing fire retardant foam. Sprinkler fitters work with a variety of pipe and tubing materials including several types of plastic, copper, steel, cast iron, and ductile iron. Standards Many countries have standards or strict guidelines pertaining to the installation and maintenance of fire sprinkler systems. United States In the US, fire protection systems must adhere to the standards set forth in the installation standards of NFPA 13, (NFPA) 13D,(NFPA) 13R, (NFPA 14) and ...

National Fire Protection Association
The National Fire Protection Association (NFPA) is a U.S.-based international nonprofit organization devoted to eliminating death, injury, property damage, and economic loss due to fire, electrical, and related hazards. , the NFPA claims to have 50,000 members and 9,000 volunteers working with the organization through its 250 technical committees. History In 1895, a Committee on Automatic Sprinkler Protection was formed in Massachusetts by men affiliated with several fire insurance companies and a pipe manufacturer to develop a uniform standard for the design and installation of fire sprinkler systems. At the time, there were nine such standards in effect within of Boston, Massachusetts, and such diversity was causing great difficulties for plumbers working in the New England New England is a region consisting of six states in the Northeastern United States: Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.

Construction Trades Workers
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning. The construction industry contributes significantly to many countries' gross domestic products ( GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many countries, but it is one of the most hazardous industries. For ...

National Center For Construction Education And Research
The National Center for Construction Education and Research, commonly referred to by the acronym NCCER, is a not-for-profit 501(c)(3) education foundation for professional craft certification, formed in 1996. Scope The mission of NCCER is to provide rigorous and relevant workforce development solutions that create opportunities for individual career advancement and support industry growth. NCCER is recognized across the United States for its breadth of trade curricula, which span over 40 trades, and its workforce development system, which includes accreditation, training, assessment, certification and career development solutions for the construction and maintenance industries. After becoming NCCER-accredited, organizations can provide programs that lead to industry-recognized credentials for their learners. The assessment for certification has two parts: the journey-level knowledge assessment and the performance evaluation. Passing both the written assessment and the performa ...

Piping And Plumbing Fitting
A fitting or adapter is used in pipe systems to connect sections of pipe (fluid conveyance), pipe (designated by Nominal Pipe Size, nominal size, with greater Engineering tolerance, tolerances of variance) or tube (fluid conveyance), tube (designated by actual size, with lower tolerance for variance), adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow. These fittings are used in plumbing to manipulate the conveyance of fluids such as water for Drinking water, potatory, irrigational, Sanitation, sanitary, and cooling, refrigerative purposes, Natural gas, gas, petroleum, Wastewater, liquid waste, or any other liquid or gaseous substances required in domestic or commercial environments, within a system of pipes or tubes, connected by various methods, as dictated by the material of which these are made, the material being conveyed, and the particular environmental context in which they will be used, such as soldering, Mortar ...

Fire Sprinkler System
A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price. Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. Fire sprinkler systems are generally designed as a life saving system, but are not necessarily designed to protect the building. Of buildings completely protected by fire sprinkler systems, if a fire did initiate, it was controlled by the fire sprinklers alone in 96% of these cases. History Leonardo da Vinci designed a sprinkler system in the 15th century. Leonardo automated his patron's kitchen with a super-oven and a system of conveyor belts. In a comedy of errors, everything went wrong during a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Fire Suppression
Automatic fire suppression systems control and extinguish fires without human intervention. Examples of automatic systems include fire sprinkler system, gaseous fire suppression, and condensed aerosol fire suppression. When fires are extinguished in the early stages loss of life is minimal since 93% of all fire-related deaths occur once the fire has progressed beyond the early stages. Types of automatic systems Today there are numerous types of automatic fire suppression systems and standards for each one. Systems are as diverse as the many applications. In general, however, automatic fire suppression systems fall into two categories: ''engineered'' and ''pre-engineered'' systems. * Engineered fire suppression systems are design specific and most commonly used for larger installations where the system is designed for a particular application. Examples include large marine and land vehicle applications, server rooms, public and private buildings, industrial paint lines, dip tan ...

Active Fire Protection
Active fire protection (AFP) is an integral part of fire protection. AFP is characterized by items and/or systems, which require a certain amount of motion and response in order to work, contrary to passive fire protection. Categories Manual fire suppression Manual fire suppression includes the use of a fire blanket, fire extinguisher, or a Standpipe (firefighting), standpipe system. Fire blanket A fire blanket is a sheet of fire retardant material that is designed to be placed over a fire to smother it out. Small fire blankets are meant for inception stage fires. They are normally made of fiberglass or Kevlar. Larger ones can be found in laboratories and factories, and are designed to be wrapped around a person whose clothes have caught fire. Fire extinguisher Fire extinguishers are devices that contain and discharge a substance that extinguishes or puts out a fire. These handheld devices come in a huge range of sizes, but the most common are portable fire extinguishers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
