Blackdamp is not coal gas . It is air without oxygen in stagnant airways where oxygen has been depleted from the atmosphere by oxidation of coal and other elements . Heavier than air , it stratifies close to the ground . Flame safety lamps will detect it by the diminished flame when carried low to the ground with it being adjusted to a 'walking flame' . Methane and other combustible gasses rise to the roof . The flame safety lamp has to be adjusted to a blue cap flame and slowly raised to the roof to detect these gasses .
Boylara: Yes, of course we can meet. Where can I find you? I'm in Pangasinan right now.
