The toxic gases in the coal mines claimed many lives and the most frequent cause, in addition to the explosions, were poisonings due to the presence of carbon monoxide (CO). Therefore, it was very important to identify the presence of this gas in the mine.

Scottish physician John Scott Haldane suggested the idea of ​​using sentinel animals: little helpers who could accompany miners and identify an eminent gas hazard before anyone else, so miners could leave dangerous mines before becoming intoxicated.

Canaries, highly sensitive to the presence of harmful gases in the air, responded more quickly than humans and thus became great allies by alerting miners to the presence of CO before any poisoning occurred. For many years these animals accompanied the miners in their work and prevented the death of thousands of them.

For this reason, the canaries became a symbol of ally to accompany the explorers: alerting them, before anyone else, of any risk in their expedition.

Just like that, we want to be the canary of your next project.
