It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called "firedamp" or "minedamp."

The more cumbersome Clanny safety lamp was successfully tested at
Carbide lamp of Dalén's previous inventions: the substrate Agamassan and the Sun valve. Inventions and improvements to carbide lamps continued for decades. After carbide lamp open flames were implicated in an Illinois coal-seam methane gas explosion that killed 54 miners, the 1932 Moweaqua Coal Mine disaster, carbide lamp use declined in United States coal mines. They continued to be used in the coal pits of other countries, notably Russia and the Ukraine.
