Arrived at dig and Estelle and Dave went to the end with bags to fill and load into buckets of watery stuff to drain as this had been proven to help a bit with water levels. The air was quite poor at the dig end. Filled about 6-8 skips with bags of watery spoil and sent up then went to the end to get on with digging. Air wasn’t great, lots of hard breathing, but not headachy, so suspicion this may be lower oxygen than a CO2 big problem. Last weeks team said it wasn’t great then either and this isn’t something we’ve had to deal with before, but it has had a long period of dry high pressures with harvesting season all around which is typical of bad air problems in caves. Estelle dug around 18 skips and then James dug 10 before the poor air drove us out and to the pub. We agreed to look to get someone to analyse the air or borrow the MCR testers as this was out if the ordinary.
