The Davy lamp was an early safety lamp used in the mining and quarrying industries. It was designed by English chemist and physicist Sir Humphrey Davy to prevent the accidental ignition of flammable gases. This was achieved by enclosing the flame of the oil-burning lamp in wire gauze that distributed heat over a large area and brought its temperature below the ignition temperature of methane. Why did the introduction of the Davy lamp initially lead to an increase in the rate of mining accidents? Discuss
