Men at Work

The Davey Lamp, invented by Sir Humphrey Davey in 1815, was a great aid in improving saftey for miners who had previously used candles for lighting underground. The lamp used naphtha for fuel. and was 10-12 inches tall. The flame was surrounded by mesh and a glass enclosure. If the light went out it indicated a lack of oxygen caused by the presence of gas.
