An important everyday task is that of servicing equipment and here technical knowledge is most important. For example the Brown-Mills breathing apparatus is stripped right down to the smallest part each time it is used, whether in training or actual operations.
Any component Showing the least sign of undue wear is replaced and the whole air circuit is washed and sterilise.
Twice a year breathing and revival equipment, at every pit in the area, must also be checked.
All the station’s breathing apparatus uses liquid oxygen, so it proved economical to instal an oxygen-making plant on the premises.
Oxygen in the Brown-Mills cylinders and in the large 50 lb containers used to replenish them, is slowly “lost” into the atmosphere, making regular checks on both necessary. The plant makes fresh liquid oxygen at the rate of 60 lbs. per hour.
