A safety lamp is a lamp (usually an oil lamp) that is relatively safe to use in atmospheres which may contain flammable gas[1].


The Irish physician William Reid Clanny invented[2] the safety lamp in 1813 after trying to find a way to prevent coal-mine explosions caused by miners using flames for illumination in the presence of flammable gases and coal dust. Here is his original illustration[2] of his safety lamp:
