[00:00:00]In 1815, Sir Humphry Davy introduced the safety [music] lamp to miners, a device designed to illuminate without igniting dangerous methane gas.

[00:00:09]The key was a fine metal gauze that cooled the flame and kept sparks from escaping, dramatically reducing explosions underground.

[00:00:17]Followed by captains of innovation, the Clanny and Hunt lamps refined safety features and added layers of protection while preserving visibility.

[00:00:26]The lamp's ripple effects reached global mining safety practices [music] and even influenced industrial regulations and training programs.

[00:00:34]A lesser-known twist is that early lamps sometimes failed under certain gas mixtures, prompting relentless refinements and renewed caution underground.
