How a simple wire mesh prevented deadly coal mine explosions
In short: This video demonstrates how chemist Humphry Davy's 1815 invention protected miners from firedamp, a flammable gas that caused countless deaths when met with open flames.
In 1815, chemist Humphry Davy discovered that a metal wire mesh could contain an explosion within a lamp, preventing it from igniting the surrounding atmosphere. This invention addressed the lethal threat of firedamp, a flammable gas found in coal mines that frequently ignited when miners used open flames for light. By surrounding a candle with metal gauze, Davy provided a way to illuminate dark tunnels without risking a catastrophic mine-wide blast.
