Brockton is a city in Plymouth County, Massachusetts, United States; the population was 105,643 at the 2020 United States census. Along with Plymouth, it is one of the two county seats of Plymouth County. It is the sixth-largest city in Massachusetts and is sometimes referred to as the "City of Champions", due to the success of native boxers Rocky Marciano and Marvin Hagler, as well as its successful Brockton High School sports programs. Two villages within it are Montello and Campello, both of which have MBTA Commuter Rail Stations and post offices. Campello is the smallest neighborhood, but also the most populous. Brockton hosts a baseball team, the Brockton Rox. It is the second-windiest city in the United States, with an average wind speed of 14.3 mph (23.0 km/h).
A boiler is a closed vessel in which fluid is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.
A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized type of pressure safety valve. A leak tight, lower cost, single emergency use option would be a rupture disk.
Sultana was a commercial side-wheel steamboat which exploded and sank on the Mississippi River on April 27, 1865, killing 1,167 people in what remains the worst maritime disaster in United States history.
A boiling liquid expanding vapor explosion is an explosion caused by the rupture of a vessel containing a pressurized liquid that has reached a temperature above its boiling point. Because the boiling point of a liquid rises with pressure, the contents of the pressurized vessel can remain a liquid as long as the vessel is intact. If the vessel's integrity is compromised, the loss of pressure drops the boiling point, which can cause the liquid to convert to a gas expanding rapidly. If the gas is combustible, as in the case with hydrocarbons and alcohols, further damage can be caused by the ensuing fire.
A fire-tube boiler is a type of boiler invented in 1828 by Mark Seguin, in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
HMS Thunderer was one of two Devastation-class ironclad turret ships built for the Royal Navy in the 1870s. She suffered two serious accidents before the decade was out and gained a reputation as an unlucky ship for several years afterward. The ship was assigned to the Mediterranean Fleet in 1878 and was reduced to reserve in 1881 before being recommissioned in 1885. Thunderer returned home in 1887 and was again placed in reserve. She rejoined the Mediterranean Fleet in 1891, but was forced to return to the UK by boiler problems the following year. The ship became a coast guard ship in Wales in 1895 and was again placed in reserve in 1900. Thunderer was taken out of service in 1907 and sold for scrap in 1909.
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition, or use of alternative energy.
The Spyros disaster was a major industrial disaster that occurred in Singapore on 12 October 1978, where the Greek tanker Spyros exploded at Jurong Shipyard, killing 76 people and injuring 69 others. It remains the worst accident, in terms of lives lost, in Singapore's post-war history. It is also Singapore's worst industrial accident.
A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level. Corrosion along the edges of lap joints was a common cause of early boiler explosions.
There have been many extremely large explosions, accidental and intentional, caused by modern high explosives, boiling liquid expanding vapour explosions (BLEVEs), older explosives such as gunpowder, volatile petroleum-based fuels such as gasoline, and other chemical reactions. This list contains the largest known examples, sorted by date. An unambiguous ranking in order of severity is not possible; a 1994 study by historian Jay White of 130 large explosions suggested that they need to be ranked by an overall effect of power, quantity, radius, loss of life and property destruction, but concluded that such rankings are difficult to assess.
Steamboats on the Columbia River system were wrecked for many reasons, including striking rocks or logs ("snags"), fire, boiler explosion, or puncture or crushing by ice. Sometimes boats could be salvaged, and sometimes not.
Vinçotte is a Belgian accredited inspection and certification organisation, that controlled 75% of the Belgian safety, reliability market in 2004. This holding is the result of a merger between two similar non-profit inspection associations : AIB and Association Vinçotte. In May 2022, Vinçotte was acquired by Kiwa, a Dutch company active in the same industry.
A naphtha launch, sometimes called a "vapor launch", was a small motor launch, powered by a naphtha engine. They were a particularly American design, brought into being by a local law that made it impractical to use a steam launch for private use.
The Lucy Walker steamboat disaster was an 1844 steamboat accident caused by the explosion of the boilers of the steamboat Lucy Walker near New Albany, Indiana, on the Ohio River. The explosion occurred on the afternoon of Wednesday, October 23, 1844, when the steamer's three boilers exploded, set the vessel on fire, and sank it. It was one of a number of similar accidents of early 19th-century riverine transportation that led to important federal legislation and safety regulations. The vessel's owner was a Native American; her crew were African-American slaves, and her passengers represented a cross-section of frontier travelers.
The ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. The document is written and maintained by volunteers chosen for their technical expertise. The ASME works as an accreditation body and entitles independent third parties to inspect and ensure compliance to the BPVC.
On the night of Wednesday, June 21, 1905, the New York Central Railroad's flagship passenger train, the 20th Century Limited, derailed in Mentor, Ohio, on the Lake Shore and Michigan Southern Railway line, killing 21 passengers and injuring more than 25 others on board. A switch from the mainline to a freight siding was open, causing the Limited to leave the mainline and overrun the siding at high speed. The cause of the accident was never officially determined, but overwhelming evidence points to an act of rail sabotage. The 20th Century Limited connected New York City to Chicago; its running time had just weeks earlier been reduced from 20 hours to 18.
The Preble Box Toe Company explosion occurred on November 8, 1928, at the company's factory in Lynn, Massachusetts. Eleven people died in the blast and resulting fires and another nine later died from their injuries, making it the deadliest explosion to occur in Greater Boston.
