Mine Disaster Response
Mine rescue or mines rescue is the specialised job of rescuing miners and others who have become trapped or injured in underground mines because of mining accidents, roof falls or floods and disasters such as explosions. Background Mining laws in developed countries require trained, equipped mine rescue personnel to be available at all mining operations at surface and underground mining operations. Mine rescue teams must know the procedures used to rescue miners trapped by various hazards, including fire, explosions, cave-ins, toxic gas, smoke inhalation, and water entering the mine. Most mine rescue teams are composed of miners who know the mine and are familiar with the mining machinery they may encounter during the rescue, the layout of workings and geological conditions and working practices. Local and state governments may have teams on-call ready to respond to mine accidents. Rescuers and equipment The first mines rescuers were the colliery managers and volunteer ...

Interactive Mine Rescue Setting (8869207692)
Across the many fields concerned with interactivity, including information science, computer science, human-computer interaction, communication, and industrial design, there is little agreement over the meaning of the term "interactivity", but most definitions are related to interaction between users and computers and other machines through a user interface. Interactivity can however also refer to interaction between people. It nevertheless usually refers to interaction between people and computers – and sometimes to interaction between computers – through software, hardware, and networks. Multiple views on interactivity exist. In the "contingency view" of interactivity, there are three levels: #Not interactive, when a message is not related to previous messages. #Reactive, when a message is related only to one immediately previous message. #Interactive, when a message is related to a number of previous messages and to the relationship between them.

Henry Fleuss
Henry Albert Fleuss (13 June 1851 – 6 January 1933) was a pioneering diving engineer, and Master Diver for Siebe, Gorman & Co. of London. Fleuss was born in Marlborough, Wiltshire in 1851. In 1878 he was granted a patent which improved rebreathers. His apparatus consisted of a rubber mask connected to a breathing bag, with (estimated) 50-60% O2 supplied from a copper tank and CO2 scrubbed by rope yarn soaked in a solution of caustic potash, the system giving a duration of about three hours. Fleuss tested his device in 1879 by spending an hour submerged in a water tank, then one week later by diving to a depth of 5.5m in open water, upon which occasion he was slightly injured when his assistants abruptly pulled him to the surface. Fleuss's apparatus was first used under operational conditions in November 1880 by Alexander Lambert, lead diver of the Severn Tunnel construction project. Trained by Fleuss, he was able to close a submerged sluice door in the tunnel which had defea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backpack
A backpack—also called knapsack, schoolbag, rucksack, rucksac, pack, sackpack, booksack, bookbag or backsack—is, in its simplest frameless form, a fabric sack carried on one's back and secured with two straps that go over the shoulders, but it can have an external frame, internal frame, and there are bodypacks. Backpacks are commonly used by hiking, hikers and students, and are often preferred to handbags for carrying heavy loads or carrying any sort of equipment, because of the limited capacity to carry heavy weights for long periods of time in the hands. Large backpacks, used to carry loads over , as well as smaller sports backpacks (e.g. running, cycling, hiking and hydration), usually offload the largest part (up to about 90%) of their weight onto padded hip belts, leaving the shoulder straps mainly for stabilising the load. This improves the potential to carry heavy loads, as the hips are stronger than the shoulders, and also increases agility and balance, since t ...

SEFA
The SEFA is a make of backpack industrial breathing set formerly made by Sabre Safety. It is an oxygen rebreather. "SEFA" is an acronym for "selected elevated flow apparatus". Description It is in a shiny backpack stainless steel sheet casing with rounded corners and edges, 16 inches wide, 21½ inches high, 6½ inches front to back. It has two wide corrugated breathing tubes leading to a fullface mask which has an inner orinasal mask and a front panel for talking through. Its breathing tubes are 22 inches long, and face forward as they come off the backpack casing. Its full duration on a filling is 2 hours. It does not have a demand valve or electronic parts, and in theory this would be fewer parts to suffer from failures. It is not designed for scuba diving, but can be used for short shallow submersion such as going through short flooded sections of underground passages. Its casing, to keep grit and stones out of its working, is completely sealed, except for a la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chokedamp
Blackdamp (also known as stythe or choke damp) is an asphyxiant, reducing the available oxygen content of air to a level incapable of sustaining human or animal life. It is not a single gas but a mixture of unbreathable gases left after oxygen is removed from the air and typically consists of nitrogen, carbon dioxide and water vapour. The term is etymologically and practically related to terms for other underground mine gases such as fire damp, white damp, and stink damp, and afterdamp. Etymology The meaning of "damp" in this term, while most commonly understood to imply humidity, presents evidence of having been separated from that newer, irrelevant meaning at least by the first decade of the 18th century, where the original relevant meaning of "vapor" derives from a Proto-Germanic origin, ''dampaz'', which gave rise to its immediate English predecessor, the Middle Low German ''damp'' (with no record of an Old English intermediary). The proto-Germanic ''dampaz'' gave rise to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Aid
First aid is the first and immediate assistance given to any person with either a minor or serious illness or injury, with care provided to preserve life, prevent the condition from worsening, or to promote recovery. It includes initial intervention in a serious condition prior to professional medical help being available, such as performing cardiopulmonary resuscitation (CPR) while waiting for an ambulance, as well as the complete treatment of minor conditions, such as applying a plaster to a cut. First aid is generally performed by someone with basic medical training. Mental health first aid is an extension of the concept of first aid to cover mental health, while psychological first aid is used as early treatment of people who are at risk for developing PTSD. Conflict First Aid, focused on preservation and recovery of an individual's social or relationship well-being, is being piloted in Canada. There are many situations that may require first aid, and many countries hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abram, Greater Manchester
Abram is a village and electoral ward in the Metropolitan Borough of Wigan, Greater Manchester, England. It lies on flat land on the northeast bank of the Leeds and Liverpool Canal, west of Leigh, southeast of Wigan, and west of Manchester. Abram is a dormitory village with a population of 9,855. Historically part of Lancashire, Abram anciently formed a township and chapelry in the parish of Wigan and hundred of West Derby. Abram appears in an entry of an ancient survey of Lancashire in 1212 under the name "Edburgham". The urbanisation and development of Abram largely coincided with the Industrial Revolution. Abram is at the centre of a coal district, and industrial scale coal mining was introduced to Abram around the middle of the 19th century with the opening of several collieries. In 1911, Abram was described as "distinctly unpicturesque ... trees are in the minority, and stunted and blackened with smoke", with "collieries, pit-banks, and railway lines" as well as "mu ...

Maypole Colliery
A maypole is a tall wooden pole erected as a part of various European folk festivals, around which a maypole dance often takes place. The festivals may occur on 1 May or Pentecost (Whitsun), although in some countries it is instead erected at Midsummer (20–26 June). In some cases the maypole is a permanent feature that is only utilised during the festival, although in other cases it is erected specifically for the purpose before being taken down again. Primarily found within the nations of Germanic Europe and the neighbouring areas which they have influenced, its origins remain unknown. It has often been speculated that the maypole originally had some importance in the Germanic paganism of Iron Age and early Medieval cultures, and that the tradition survived Christianisation, albeit losing any original meaning that it had. It has been a recorded practice in many parts of Europe throughout the Medieval and Early Modern periods, although it became less popular in the 18th an ...

Coal Mines Act Of 1911
The Coal Mines Act 1911 amended and consolidated legislation in the United Kingdom related to collieries. A series of mine disasters in the 19th and early-20th centuries had led to commissions of enquiry and legislation to improve mining safety. The 1911 Act, sponsored by Winston Churchill, was passed by the Liberal government of H. H. Asquith. It built on earlier regulations and provided for many improvement to safety and other aspects of the coal mining industry. An important aspect was that mine owners were required to ensure there were mines rescue stations near each colliery with equipped and trained staff. Although amended several times, it was the main legislation governing coal mining for many years. Background In the United Kingdom a series of disasters in the 19th century brought about Royal Commissions which developed the idea of improving mine safety. In 1906 a major explosion at a colliery in Courrières, northern France, caused the deaths of more than 1,000 miners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howe Bridge Mines Rescue Station
Howe Bridge Mines Rescue Station was the first mines rescue station on the Lancashire Coalfield opened in 1908 in Howe Bridge, Atherton, then in the historic county of Lancashire, England. Before Britain's first mines rescue station opened at Tankersley in Yorkshire in 1902, pit managers and volunteers were usually the first untrained mines rescuers. They fought fires, rescued victims and recovered bodies in the collieries in which they worked. Rescue stations were recommended in a Royal Commission in 1886 but were not compulsory until after the 1911 Coal Mines Act was passed. In 1906 the Lancashire and Cheshire Coal Owners Association formed a committee which decided to provide a mines rescue station in Lovers Lane Atherton. The first rescuers were provided with Siebe Gorman Proto breathing apparatus which was selected by competition. A team from the rescue station was tasked with training rescue teams from each colliery, and provided emergency assistance to collieries throu ...

Rebreather
A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's breathing, exhaled breath to permit the rebreathing (recycling) of the substantially unused oxygen content, and unused inert content when present, of each breath. Oxygen is added to replenish the amount metabolised by the user. This differs from open-circuit breathing apparatus, where the exhaled gas is discharged directly into the environment. The purpose is to extend the breathing endurance of a limited gas supply, and, for covert military use by frogmen or observation of underwater life, eliminating the bubbles produced by an open circuit system and in turn not scaring wildlife being filmed. A rebreather is generally understood to be a portable unit carried by the user. The same technology on a vehicle or non-mobile installation is more likely to be referred to as a life-support system. Rebreather technology may be used where breathing gas supply is limited, such as underwater or in space, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
