Concentrated pockets of gas are often a problem in mines. To combat the gas problem, the miner would be dressed in a dampened coat and given a long stick with a burning torch on the end. These miners would crawl along the floor with the torch raised until the fire and pocket of gases met. The flame would, in theory, pass over the miner, and the miner would be able to retreat safely. It was not until the early 19th century that the invention of safety lamps would help to reduce the number of mining-related injuries and deaths significantly.
