Hi,
this has probably been covered numerous times on here but could someone explain about bad air to me? Mainly I would like to know how much of a problem it generally is in caves and the signs etc. I have read somewhere that using a cigerette lighter can help to guage the air quality and if it won't light then that is a sign of very bad air? However I have always been under the impression that naked flames underground are dangerous.
Thanks in advance.
