Had a warning from COMRU today about bad air in Haggs.
They held an exercise in Brownley Hill mine today and ended looking in to Haggs. Just past the junction for Admiralty Flats they stopped for a smoke break and non of their lighters would burn at all.
Retreated feeling dizzy and tired, the air did not improve until they got back up into Brownley.
Bear this in mind if you are visiting.
