Even with all of the proper tools at hand, I've always found mining to be a very dangerous job, despite not having any direct experience with it myself.
After all, not only could one have problems down there with a lack of oxygen, but even more so, there have been countless stories of workers who have been trapped due to explosions or cave-ins. From footage I've seen on the news.
On a brighter note though, the Davy lamp does sound very beneficial, and from reading the bullet point, it certainly seems to help with problems that people had before. I mean, before it was built, how were people supposed to even tell how much oxygen they had?
Overall though, despite all the advancements in technology, I still feel like you should always be prepared for the worst when in a mine, as anything can happen down there. Does anyone else feel the same way? It really makes me wonder what other tools people bring to mines now in this day and age.
