In 1815, Sir Humphry Davy, a British chemist, introduced the Davy lamp, a safe light source for miners. The lamp used a fine mesh screen to separate the flame from potentially explosive gases like methane, reducing ignition risks in mines. This safety innovation was widely adopted, significantly improving miners' safety and enhancing productivity in the industry. The Davy lamp thus played a pivotal role in minimizing mining accidents and supporting economic growth through safer extraction of coal and minerals.
