meaning and origin of ‘canary in the coal mine’
The phrase a , or the , canary in a , or the , coal mine denotes an early indicator of potential danger or failure. It refers to the former practice of taking live canaries into coal mines to test for the presence of toxic gases, particularly carbon monoxide, the illness or death of the canaries serving as an indication that such gases were present. The earliest mention of this practice that I have found is from the Yorkshire Telegraph and Star Sheffield, Yorkshire of Friday 21 st December , which gave an account of the inquest that had been held the previous day at Ouston, near Chester-le-Street, on the four victims of an explosion at Arpeth pit:. Blackett, a mining expert, said that along with the Mines Inspector he made an attempt to reach the scene of the explosion, taking with him a canary in a cage, a safety lamp, and an electric hand lamp. They were well equipped to explore the workings with safety. Upon reaching a point beyond which it had hitherto been impossible to penetrate, they got a competent man to test the place with a safety lamp, and finding only a small bluecap, he took a deep breath, and with the electric lamp and the bird he made a rapid advance, left the bird , and retired. Returning with the safety lamp, and finding the bird on its perch, he advanced again and again in the same way, until he and the inspector came to the place where a body was lying.
Sentinel species are organisms , often animals, used to detect risks to humans by providing advance warning of a danger. The terms primarily apply in the context of environmental hazards rather than those from other sources. Some animals can act as sentinels because they may be more susceptible or have greater exposure to a particular hazard than humans in the same environment. Plants and other living organisms have also been used for these purposes. There are countless examples of environmental effects on animals that later manifested in humans.
