2018 Borgo Panigale Explosion
On 6 August 2018, the collision of a liquefied petroleum gas (LPG) road tanker with an articulated lorry carrying flammable solvents and a car transporter resulted in a huge explosion on the A14 motorway within Borgo Panigale, a neighbourhood of Bologna, Italy. It was a case of boiling-liquid expanding-vapour explosion (BLEVE), where nearly all the road tanker cargo combusted in a matter of seconds upon release, generating a tremendous amount of thermal radiation. The accident killed two people, injured 145 and caused significant damage to the surrounding commercial and residential area. One span of the viaduct where it happened collapsed and a gash opened in the motorway. Vehicle collision The collision involved a liquefied petroleum gas (LPG) road tanker, another articulated lorry carrying flammable solvents and a car transporter. It took place on the northbound carriageway of the ''ramo Casalecchio'' (Casalecchio branch) of the A14 motorway, which connects the A1 motorw ...

La Repubblica
(; English: "the Republic") is an Italian daily general-interest newspaper with an average circulation of 151,309 copies in May 2023. It was founded in 1976 in Rome by Gruppo Editoriale L'Espresso (now known as GEDI Gruppo Editoriale) and led by Eugenio Scalfari, Carlo Caracciolo, and Arnoldo Mondadori Editore as a leftist newspaper, which proclaimed itself a "newspaper-party" (). During the early years of , its political views and readership ranged from the reformist left to the extraparliamentary left. Into the 21st century, it is identified with centre-left politics, and was known for its anti- Berlusconism, and Silvio Berlusconi's personal scorn for the paper. In April 2020, the paper was acquired by the GEDI Gruppo Editoriale of John Elkann and the Agnelli family, who is also the founder and owner of . Maurizio Molinari, the then editor of , was appointed as 's editor in place of ; this prompted the resignation of several journalists opposed to this change. Un ...

Pascal (unit)
The pascal (symbol: Pa) is the unit of pressure in the International System of Units (SI). It is also used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m2). It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar. The unit of measurement called '' standard atmosphere (atm)'' is defined as . Meteorological observations typically report atmospheric pressure in hectopascals per the recommendation of the World Meteorological Organization, thus a standard atmosphere (atm) or typical sea-level air pressure is about 1013 hPa. Reports in the United States typically use inches of mercury or millibars (hectopascals). In Cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest viaduct in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freigh ...

ADR (treaty)
ADR, formally the Agreement of 30 September 1957 concerning the International Carriage of Dangerous Goods by Road is a 1957 United Nations multilateral treaty, treaty that governs transnational transport of hazardous materials. "ADR" is derived from the French name for the treaty: ''Accord relatif au transport international des marchandises Dangereuses par Route''). Until 31 December 2020, the treaty was fully named European Agreement concerning the International Carriage of Dangerous Goods by Road. However, as the word "European" might have given the impression that the treaty was only open for accession to European states, an amendment was decided in the end of 2019. Concluded in Geneva on 30 September 1957 under the aegis of the United Nations Economic Commission for Europe, it entered into force on 29 January 1968. The agreement was modified (article 14, paragraph 3) in New York City on 21 August 1975, though these changes only took effect on 19 April 1985. A new amended ADR 2 ...

Relief Valve
A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire. Pressure relief Excess pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the " path of least resistance" as the valve is forced open and a portion of the fluid is diverted through the auxiliary route. In systems containing flammable fluids, the diverted fluid (liquid, gas or liquid-gas mixture) is either recaptured by a low pressure, high-flow vapor recovery system or is routed through a piping system known as a ''flare header'' ...

Pool Fire
A pool fire is a type of diffusion flame where a layer of volatile liquid fuel is evaporating and burning. The fuel layer can be either on a horizontal solid substrate or floating on a higher-density liquid, usually water. Pool fires are an important scenario in fire process safety and combustion science, as large amounts of liquid fuels are stored and transported by different industries. Physical properties The most important physical parameter describing a pool fire is the heat release rate, which determines the minimum safe distance needed to avoid burns from thermal radiation. The heat release rate is limited by the rate of evaporation of the fuel, as the combustion reaction takes place in the gas phase. The evaporation rate, in turn, is determined by other physical parameters, such as the depth, surface area and shape of the pool, as well as the fuel boiling point, heat of vaporization, heat of combustion, thermal conductivity and others. A feedback loop exists between the he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pressure Vessel
A pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Construction methods and materials may be chosen to suit the pressure application, and will depend on the size of the vessel, the contents, working pressure, mass constraints, and the number of items required. Pressure vessels can be dangerous, and fatal accidents have occurred in the history of their development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. For these reasons, the definition of a pressure vessel varies from country to country. The design involves parameters such as maximum safe operating pressure and temperature, safety factor, corrosion allowance and minimum design temperature (for brittle fracture). Construction is tested using nondestructive testing, such as ultrasonic testing, radiography, and pressure tests. Hydrostatic pressure t ...
