  2. Safety lamp - Wikipedia

    en.wikipedia.org/wiki/Safety_lamp

    A safety lamp has to ensure that the triangle of fire is maintained inside the lamp, but cannot pass to the outside. Since any breathable atmosphere contains oxygen, and a safety lamp's raison d'être is to operate in an atmosphere also containing fuel (firedamp or coal dust), the element which must be blocked is heat. The key to manufacturing ...

    en.wikipedia.org/wiki/Davy_lamp

    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.

    The society aimed for greater publicity for accidents and their causes, the scientific study of ventilation, and the development of safety lamps. Stephenson designed a safety lamp, known as the Geordie lamp, with air fed through narrow tubes, down which a flame could not move. It also led Sir Humphry Davy to devise another safety lamp, the Davy ...

    Stephenson's safety lamp shown with Davy's lamp on the left. The Geordie lamp was a safety lamp for use in flammable atmospheres, invented by George Stephenson in 1815 as a miner's lamp to prevent explosions due to firedamp in coal mines.

  6. Calcium carbide - Wikipedia

    en.wikipedia.org/wiki/Calcium_carbide

    The presence of flammable gases in coal mines led to miner safety lamps such as the Davy lamp, in which a wire gauze reduces the risk of methane ignition. Carbide lamps were still used extensively in slate, copper, and tin mines where methane is not a serious hazard. Most miners' lamps have now been replaced by electric lamps.

    By 1816, when Clanny published Practical observations on safety lamps for coal mines, he had experimented in person with a safety lamp at the Mill Pit in Herrington near Sunderland, [5] [a] where there had been a serious explosive accident, with the loss of 24 lives, on 10 October 1812. [6]
