Throughout much of the 20th century, chirping canaries were staples of the coal mining industry. As coal miners descended into the earth—entering a harsh environment often home to poisonous gases like carbon monoxide—they would bring the yellow birds along as safety mechanisms. Because carbon monoxide is clear and odorless, miners needed a method for detecting a leak before it killed them. In December , Britain officially outlawed the usage of canaries in the coal mines. At the time, it was the latest of many changes in the British mining industry, which was a source of great strife in the country through the s. The last one retired in

The canary in the coal mine meaning

Most of us see bright-feathered, warbling canaries as pets, yet these tiny birds were not always just household companions. In the nineteenth century they were used as exceptional risk predictors in mines. This was because they were particularly sensitive to carbon monoxide, a substance which led to numerous mining accidents in the aftermath of industrialisation. Thus, oddly, an increasing reliance on fossil fuels induced a new rapport with nature and animals. Risk management in mines became a major source of concern during the nineteenth century. The Term Frequency tool in Gale Primary Sources shows a great rise in discussion in the press about mines and risk between and While this upsurge of articles is also a direct consequence of the rising production of newspapers, it is also representative of increasing awareness of the risks tied to mining and attempts to reduce them through the use of supposedly safer equipment and risk-prediction technologies. In the nineteenth century, coal mining developed into a vital industry, as steam engines and railways became increasingly widespread. Whilst new technologies allowed deeper and deeper mines, miners were exposed to increasingly dangerous working environments and often fell victim to explosions and poisonous gases. It can also quickly build up in the body, which made it essential to find ways to swiftly detect its presence in the air. It was soon discovered that a canary would immediately show signs of distress in the presence of carbon monoxide and die well before a human would begin to feel the effects of carbon monoxide poisoning, thus they came to play a crucial role in detecting these toxic gases and managing hazards in the mine. The practice began in the last decades of the nineteenth century. In , canaries were used by a rescue team to enter a mine in the aftermath of an explosion see below. The canary was described as most useful and in some instances they were produced as evidence during investigations of industrial accidents.

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, England 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. He saw at once that the man had died from after-damp, and was not burned. Still advancing in this way, they presently came to a stentor where another man had been working. Here he saw the bird fall from its perch, and, incautiously taking a breath of the air himself, his knees gave way to a small extent, but he managed to scramble out into the better air, taking the bird with him.

Log In. My Account. When exposed to toxic gases, canaries suffer ill effects and die sooner than humans do. If the canaries became sick or died, this was a sign that something was seriously amiss and that the miners needed to get out. The practice was phased out, at least in the U. The canary is not prophetic until it is brought in the coalmine, so the metaphor works especially well if the prophetic thing is small, innocent, and not prophetic under normal circumstances. Few writers take pains to make the metaphor perfectly logical, though, and most so-called canaries in coalmines are just things that should be considered alarming.
