The Sussmann lamp [58] was introduced into Britain in 1893 and following trials at Murton Colliery in Durham it became a widely used electric lamp with 3000 or so reported by the company in use in 1900 [59] However, by 1910 there were only 2055 electric lamps of all types in use – about 0.25% of all safety lamps.

Mining accidents can occur from a variety of causes, including leaks of poisonous gases such as hydrogen sulfide [2] or explosive natural gases, especially firedamp or methane, [3] dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment).

Unlike ATEX which uses numbers to define the safety "Category" of equipment (namely 1, 2, and 3), the IEC continued to utilise the method used for defining the safe levels of intrinsic safety namely "a" for zone 0, "b" for zone 1 and "c" for zone 2 and apply this Equipment Level of Protection to all equipment for use in hazardous areas since ...
The explosion was about 70 miles (112 km) northwest of East Palestine, Ohio, where earlier this month a train loaded with toxic chemicals derailed, causing a fire that sent a cloud of smoke over ...
A type of Davy lamp with apertures for gauging flame height. The lamp consists of a wick lamp with the flame enclosed inside a mesh screen. The screen acts as a flame arrestor; air (and any firedamp present) can pass through the mesh freely enough to support combustion, but the holes are too fine to allow a flame to propagate through them and ignite any firedamp outside the mesh.
An explosion at a chain home improvement store in northeastern Romania on Friday injured at least 13 people, one seriously, authorities said. A mobile intensive care unit was dispatched to the ...
A paper 'On the Means of procuring a Steady Light in Coal Mines without the Danger of Explosion' was read before the Royal Society on 20 May the following year. [1] Such early machines were large and cumbersome but Clanny ultimately succeeded in reducing the weight of the lamp to 34 ounces (964 grams). [4]
