chokedamp /ˈtʃəʊkˌdæmp/	chokedamps /ˈtʃəʊkˌdæmpz/

chokedamp /[ˈtʃəʊkˌdæmp/

1. Gaz asphyxiant (gaz à faible teneur en oxygène et ne permettant pas la vie, rencontré dans les mines après un coup de grisou)

   • CHOKE-DAMP : the name given by miners to the irrespirable gas (carbonic acid) which fills the mine after an explosion of fire-damp. This gas is also found in badly ventilated parts of mines, its presence being detected by the difficulty of making candles burn, and the violent headaches it brings upon those who remain for any time where it is abundant. "When carbonic oxide is present, the gas is exceedingly dangerous to breathe for an instant; but one may sometimes stay with safety for a minute or two in an atmosphere of choke-damp in which a candle cannot be lighted. (The new American cyclopaedia- George Ripley)
