Word Origin & History

damp
early 14c., probably in O.E., but no record of it. If not, probably from M.L.G. damp; ult. from P.Gmc. *dampaz. Originally "a noxious vapor;" sense of "moisture" is first attested 1706. Damper of a piano is from 1783; of a chimney, 1788; either or both of which led to various figurative senses.

damp

any of various harmful vapours produced during mining operations. The gases are frequently called damps (German Dampf, "vapour"). Firedamp is a gas that occurs naturally in coal seams. The gas is nearly always methane (CH4) and is highly inflammable and explosive when present in the air in a proportion of 5 to 14 percent. White damp, or carbon monoxide (CO), is a particularly toxic gas; as little as 0.1 percent can cause death within a few minutes. It is a product of the incomplete combustion of carbon and is formed in coal mines chiefly by the oxidation of coal, particularly in those mines where spontaneous combustion occurs. Black damp is an atmosphere in which a flame lamp will not burn, usually because of an excess of carbon dioxide (CO2) and nitrogen in the air. Stinkdamp is the name given by miners to hydrogen sulfide (H2S) because of its characteristic smell of rotten eggs. Afterdamp is the mixture of gases found in a mine after an explosion or fire
