Question

Who invented the safety lamp?
A.Humphrey Davy
B.Faraday
C.Henry Cort
D.John Smeaton

Answer 1

Hint:He is a famous Cornish chemist and inventor. He was awarded for the invention of Davy’s lamp. His invented lamps are now used by many coal mines. He was the president of the Royal Society. He is the person who discovered the elemental nature of chlorine and iodine.

Complete answer:
The safety lamp was invented by Sir Humphry Davy in 1815. The safety lamp is the first-ever prototype of Davy’s miner’s safety lamp. The safety lamp was designed to safely light the lamp for miners to use without allowing the heat to explode dangerous gas. A Safety lamp is a lamp used in a flammable atmosphere. It is used in coal mines, to reduce the danger of explosion due to the presence of inflammable gases. In modern times, these safety lamps are used in the Olympic flame torch relays and other Olympic games. Safety lamps are developed to enclose the flame and prevent it from igniting the surrounding atmosphere.
Humphry Davy (1778 - 1829) is a Cornish Chemist who invented a safety lamp. He got awarded for his work on safety lamps. The safety lamps were started in mines from 1816. Humphry Davy became the President of the Royal Society in 1820. Davy has discovered calcium, magnesium, strontium, and barium. Some of the contributions of Humphry include the study of nitrous oxide gas, which could be used to relieve the pain of surgery. He also discovered the chemical elemental nature of both chlorine and iodine. Through his works, he invented the new field of electrochemistry and which is used for future references. Safety lamps discovered by Davy helps the miners to detect low levels of oxygen, to reduce possibilities of explosions, and saves many lives from danger. In $1869$, in the honor of Humphry Davy established a Davy medal. It is discovered that the safety lamps had brought many accidents in coal mines.

Hence, the correct answer is option (A).

Note: For the invention of the Safety lamp, the Royal Society awarded Davy with the Rumford Medal. He made a Baronet for his services to the industry. He was a member of the Royal Irish Academy and a fellow of the Gerontological Society.
