2022 Sheffield Gas Supply Outage
The city of Sheffield, England was impacted by a major failure of the local natural gas supply network in December 2022, resulting in a loss of central heating and gas stove availability to more than 3,000 properties in the northwestern suburbs of the city. The outage, which has predominantly affected the Hillsborough, Malin Bridge and Stannington districts, was declared a major incident by Sheffield City Council; some properties were without a gas supply for almost two weeks. The gas supply outage affected the Cadent Gas network, and was caused by a burst water main on the Yorkshire Water network which resulted in more than 2 million litres of water flooding into the gas supply network. Yorkshire Water confirmed that the breach to the water main had been resolved by 6 December. In addition to the widespread gas supply outage, numerous properties in the affected areas have also suffered from outages to their water and electricity supplies as knock-on effects. Heavy r ...

Stannington, Sheffield
Stannington is a suburb in the City of Sheffield, England. The area is located in the civil parish of Bradfield, and is in the electoral ward of Stannington. Stannington is situated on the western edge of the Sheffield urban area History and description Stannington is a suburb of Sheffield to the west of the city centre, located on the hill between the River Rivelin and River Loxley. There is evidence of Roman occupation of the area which comes from tablets found on the Stannington side of the Rivelin Valley (bronze artefacts, Stannington Diploma of A.D. 124, found 1761, now in the British Museum) which record the granting of land to retiring Roman auxiliaries of the Sunuci tribe. Other evidence of nearby Roman occupation comes from finds on Walkley Bank Road, which leads onto the ridge facing Stannington. The village has grown from the two settlements of Upper Gate and Nethergate. The settlement was mentioned in medieval times when a charter was granted to all men of Stann ...

Asbestos
Asbestos () is a naturally occurring fibrous silicate mineral. There are six types, all of which are composed of long and thin fibrous crystals, each fibre being composed of many microscopic "fibrils" that can be released into the atmosphere by abrasion and other processes. Inhalation of asbestos fibres can lead to various dangerous lung conditions, including mesothelioma, asbestosis, and lung cancer, so it is now notorious as a serious health and safety hazard. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos is an excellent electrical insulator and is highly fire-resistant, so for much of the 20th century it was very commonly used across the world as a building material, until its adverse effects on human health were more widely acknowledged ...

Public House
A pub (short for public house) is a kind of drinking establishment which is licensed to serve alcoholic drinks for consumption on the premises. The term ''public house'' first appeared in the United Kingdom in late 17th century, and was used to differentiate private houses from those which were, quite literally, open to the public as "alehouses", "taverns" and "inns". By Georgian times, the term had become common parlance, although taverns, as a distinct establishment, had largely ceased to exist by the beginning of the 19th century. Today, there is no strict definition, but CAMRA states a pub has four characteristics:GLA Economics, Closing time: London's public houses, 2017 # is open to the public without membership or residency # serves draught beer or cider without requiring food be consumed # has at least one indoor area not laid out for meals # allows drinks to be bought at a bar (i.e., not only table service) The history of pubs can be traced to Roman taverns in B ...

Hotplate
A hot plate is a portable self-contained tabletop small appliance cooktop A cooktop (American English), stovetop (American English) or hob (British English), is a device commonly used for cooking that is commonly found in kitchens and used to apply heat to the base of pans or pots. Cooktops are often found integrated ... that features one or more electric heating elements or gas burners. A hot plate can be used as a stand-alone appliance, but is often used as a substitute for one of the burners from an oven range or a kitchen stove. Hot plates are often used for food preparation, generally in locations where a full kitchen stove would not be convenient or practical. They can also be used as a heat source in laboratories. A hot plate can have a flat surface or round surface. Hot plates can be used for traveling or in areas without electricity. Description This type of cooking equipment is typically powered by electricity; however, gas fired hot plates were not uncommon in t ...

Electric Heater
Electric heating is a process in which electrical energy is converted directly to heat energy at around 100% efficiency, using rather cheap devices. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current into heat. The heating element inside every electric heater is an electrical resistor, and works on the principle of Joule heating: an electric current passing through a resistor will convert that electrical energy into heat energy. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. Alternatively, a heat pump can achieve around 300% efficiency for heating, or 3.0 Coefficient of performance, because it uses electric power only for transferring existing thermal energy from the surrounding area, mostly air. The heat pump uses an electric moto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Church Hall
A church hall or parish hall is a room or building associated with a church, generally for community and charitable use. '''', , July 2001. In smaller and village communities, it is often a separate building near the church, while on more restricted urban sites it may be in the basement or a wing of the main church building. Activities in the hall are not necessarily religious, but parts of |
Freezing Point
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point. Because of the ability of substances to supercool, the freezing point can easily appear to be below its actual value. When the "characteristic freezing point" of a substance is determined, in fact, the actual methodology is almost always "the principle of observing the disappearance rather than the formation of ice, that is, the melting point." Examples For most substances, melting and freezing points are approximately equal. For example, the melting point ''and'' freezing point of mercury is . Ho ...

Electric Car
An electric car, battery electric car, or all-electric car is an automobile that is propelled by one or more electric motors, using only energy stored in batteries. Compared to internal combustion engine (ICE) vehicles, electric cars are quieter, have no exhaust emissions, and lower emissions overall. In the United States and the European Union, as of 2020, the total cost of ownership of recent electric vehicles is cheaper than that of equivalent ICE cars, due to lower fueling and maintenance costs. Charging an electric car can be done at a variety of charging stations; these charging stations can be installed in both houses and public areas. Worldwide, 6.6 million plug-in electric cars were sold in 2021, more than doubling 2020 sales, and achieving a market share of 9% of the global new car market. All-electric cars represented 71% of plug-in car sales in 2021. , 16 million plug-in electric cars were on the world's roads. Many countries have established government ...

Power Outage
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Network
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potenti ...

Street Light
A street light, light pole, lamp pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led. Many lamps have light-sensitive photocells that activate the lamp automatically when needed, at times when there is little-to-no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions. This function in older lighting systems could be performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another. Street lights are an important source of public security lighting intended to reduce crime. History Preindustrial era Early lamps were used by Greek and Roman civilizations, where light primarily served the purpose of ...

Gas Meter
A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, because measured volumes are highly affected by temperature and pressure. Gas meters measure a defined volume, regardless of the pressurized quantity or quality of the gas flowing through the meter. Temperature, pressure, and heating value compensation must be made to measure actual amount and value of gas moving through a meter. Several different designs of gas meters are in common use, depending on the volumetric flow rate of gas to be measured, the range of flows anticipated, the type of gas being measured, and other factors. Gas meters that exist in colder climates in buildings built prior to the 1970s were typically located inside the home, typically in the basement or garage ...
