Original use
The isolated breathing apparatus was used in the Idrija Mercury Mine rescue unit. The breathing apparatus, which they carried on their backs, provided oxygen to the rescuers during interventions. The oxygen passed from the potassium steel flask into the breathing bag. Then, potassium was bound with carbon dioxide from the exhaled air. The Mine’s rescue unit already existed before 1945 (the first such apparatus was already ordered in 1847), but it was poorly equipped and disorganised. After 1953, the implementation of hygienic and technical protection at work significantly improved the organisation. In 1956, the Idrija Mercury Mine rescue team was divided into two units, the pit unit and the smelting plant unit. The rescue team members were appropriately trained for protection and rescuing in the event of work related accidents or other hazards.
Present use
The isolated breathing apparatus (5 in total) are being preserved, secured and presented as important mining heritage of Idrija with exceptional universal values. They are a part of the mine collection of the Idrija Municipal Museum. They are stored in the depot. They may be used for temporary museum exhibitions and various forms of promotion of mercury heritage.
