Detection and countermeasures. Historically the domestic canary was used as an early warning against any asphyxiating gases. In active mining operations the threat from blackdamp is addressed with proper mineshaft ventilation as well as various detection methods typically using miner s safety lamps or hand-held electronic gas detectors. The

1986 Coal mine canaries made redundant More than 200 canary birds are being phased out of Britain s mining pits according to new plans by the government. Modern technology is being favoured over the long-serving yellow feathered friend of the miner in detecting harmful gases which may be present underground.

Carbon monoxide in mines can be extremely hazardous to all personnel. MineARC Refuge Chambers are equipped with three different technologies to monitor Carbon Monoxide levels and remove the harmful gas from within occupied refuge chambers to maintain a safe breathable atmosphere.

The Spero sensor (S1) is an ionization-type smoke sensor that uses Krypton 85 to ionize the air space between two electrodes. It has been approved in South Africa for use in underground hazardous locations and is commonly used for fire detection in South African mines. It is not approved for use in U.S. underground coal mines.
