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.

If the animal became ill or died, that would give miners a warning to evacuate. Because they need such immense quantities of oxygen to enable them to fly and fly to heights that would make people altitude sick, their anatomy allows them to get a dose of oxygen when they inhale and another when they exhale, by holding air in extra sacs, he writes.
