Afterdamp: air containing dangerous amounts of carbon monoxide.
Banksman: The man at the surface in charge of the pit bank. He is responsible for the loading and unloading of the cage.

The Davy Lamp: Invented by Sir Humphry Davy after a dreadful disaster at the Felling Colliery in 1812. The safety lamp uses a metallic gauze to cover the flame so that it cannot ignite the methane gas (or firedamp) in the mines. The lamp has the added advantage of the flame changing colour in reaction to different levels or concentrations of methane gas.
Firedamp: This is the name miners give to methane gas. The gas appears naturally in coal seams and can be the cause of dreadful accidents.
