	Davy lamp - Wikipedia, the free encyclopedia
		The Davy lamp is a candle containing safety lamp devised in 1815 by Humphry Davy.
		The first trial of a Davy lamp with a wire sieve was at Hebburn Colliery on 9 January 1816.
		Miners could also place a safety lamp close to the ground to detect gases, such as carbon dioxide, that are denser than air and so could collect in depressions in the mine, if the mine air was oxygen-poor, the lamp flame would be extinguished (chokedamp).

	Safety lamp - Wikipedia, the free encyclopedia
		Safety lamp is the name of a variety of lamps for safety in coal-mines against coal dust, methane, or firedamp, a highly explosive mixture of natural gas apt to accumulate in them.
		Prior to the invention of these safety lamps, miners used canaries to alert them to the presence of gas, and barometers to tell them if atmospheric pressure was low (in which case more methane seeped out of the mine into the air).
		Nowadays, safety lamps are mainly electric, and traditionally mounted on miners' helmets, sealed to prevent gas penetrating the casing and being ignited by electrical sparks.

		The flame in the lamp is surrounded by a metal-gauze screen that distributes the heat over a large area so that the maximum temperature of the screen is below the ignition temperature of the flammable gas mixture (e.g., firedamp).
		If firedamp or related gas mixtures are present in a mine, the Davy lamp flame burns higher and with a blue halo; the height of the flame and color of the halo indicate the amount of combustible gas in the air.
		Coal miners often placed the safety lamp close to the ground to detect gases, e.g., carbon dioxide, that are denser than air and thus collect in poorly ventilated depressions in the mine.

	Who Invented the Flame Safety Lamp
		The invention of the flame safety lamp is often attributed to Sir Humphrey Davy, the renowned Cornish scientist and scholar.
		The constant development of flame safety lamps to meet the changing needs of miners for safe, effective lighting, and the detection of dangerous mine atmospheres has resulted in a huge diversity in lamp design and construction, which makes their collection such a satisfying pastime.
		Clanny's first lamp, which he developed in 1813 and presented to the Royal Society in a lecture, used a water trap at the inlet and outlet to the lamp, and a set of bellows was used to force air through the lamp to keep the flame alight.

	Safety Lamp History
		Stephenson's third lamp was a success, and with modifications was successfully used in coal mines mainly in the North of England.
		Early on in the development of the flame safety lamp, it was realized that it could be used for gas measuring purposes.
		But, safety lamps still continued to be use for detecting and measuring gas long after their use for lighting was obsolete.

		The danger of methane gas (firedamp) being ignited by an open flame in coal mines was much reduced by the development of the flame safety lamp stemming from the work of Dr. William Clanny, George Stephenson and Sir Humphrey Davy.
		It is Davy who is credited with the true invention of the flame safety lamp in 1816.
		It was found that the greatest safety could be obtained by a standard mesh formed by 28 steel wires per inch making 784 openings per square inch.

	Davy lamp -- Encyclopædia Britannica
		Arc lamps are used in applications requiring great brightness, as in searchlights, large film projectors, and floodlights.
		In the late 18th century a demand arose in England for a miner's lamp that would not ignite the gas methane (firedamp), a common hazard of English coal mines.
		The inventor of the Davy safety lamp was Humphry Davy, an English chemist who made many notable contributions to science, especially in electrochemistry.

	The Flame Safety Lamp.
		Many variations of flame safety lamps were tried over many years, but their accuracy in determining the amount of methane gas present was questioned when it was discovered that air could be circulating around the lamp (I think caused by heat from the lamp) this resulted in a false percentage of methane being estimated.
		The flame safety lamp also detects oxygen deficiency, known by miners as fldamp, a mixture of air and carbon dioxide (CO2) which could be found near the floor, usually where the ventilation is inadequate.
		This was the lamp I used, the Garforth flame safety lamp.

	NJDEP-Radiation Protection Programs
		Mercury vapor lamps are widely used to light both indoor and outdoor areas such as gymnasiums, factories, department stores, banks, highways, parks and sports fields.
		This type of lamp should only be used in a totally enclosed lighting fixture with a glass or plastic shield that will absorb the hazardous UV radiation, or in areas where people will not be exposed to UV radiation if the outer globe is broken.
		The requirements state that for indoor use, the mercury vapor lamp must be of the self-extinguishing type or if it is non-extinguishing, it must be installed within a totally enclosed lighting fixture with a protective shield which protects the lamp for damage and absorbs shortwave UV radiation.

		The safety lamp, the miner's best friend, will briefly explained by its nature and properties, in the hope that the consideration of it may induce many of you to prize more highly one of the most important benefits that ever humanity derived from science.
		The flame of the safety lamp is surrounded by a gauze cylinder, made of iron or copper wire.
		Should the gauze be courser, or of fewer spaces than 24 to one inch, the lamp would be useless as a protection, should the be much finer, sufficient light would not be emitted to enable the miner to work.

	Safety
		Such lamps are generally considered to have been a boon to miners, and to have lead to a dramatic reduction in underground explosions and fires.
		Between the date of the first public demonstration of a working flame safety lamp in December, 1815 and the outbreak of World War 2 in 1939, when electric lamps slowly began to be widely used, about 12,800 died in explosions in underground coal mines.
		Although many jurisdictions still require the use of flame safety lamps for gas testing, there is no doubt that their use is diminishing, and that their heyday is long since past.

	The Irony Of The Safety Lamp - John Taylor Gatto
		Davy’s assignment to the honor roll of saintliness came from his assertion that the sole object of his concern was to "serve the cause of humanity"—a declaration made credible by his refusal to patent the device.
		Let nobody deny that the safety lamp decreased the danger of explosion relative to older methods of illumination, but the brutal fact is that many more miners died because of Davy’s invention.
		Davy’s "safety" lamp brought safety only in the most ironic sense; it was a profit-enhancement lamp most of all.

		Sir Humphry Davy invented his flame safety lamp in 1816 and, even though safety lamps were developed independently by Clanney and Stephenson, it was the Davy lamp that became most widely used in English coal mines.
		Another important safety attribute of the Davy lamp was that, if the flame went out on a properly maintained lamp, miners would be alerted to the fact that dangerously low levels of oxygen may have been present.
		The Butane Lamp Methanometer developed by SMRE in 1961 used a thermocouple to measure the heat developed by the combustion of methane in a controlled pure butane flame housed in a modified flame safety lamp.

		In 1906, nearly 53 percent of mine explosions were still caused by miners' lamps, and in 1912, the U.S. Bureau of Mines reported that at least two disasters had been caused by safety lamps.
		The Cage lamp was safe where gasses had collected; it produced twice as much light as the safety lamp; its storage battery provided enough electrical energy to last sixteen hours, or two shifts; and it was tough enough to withstand rough treatment.
		Illumination was provided by a tungsten lamp that had "a parabolic reflector and a heavy lens to distribute the light over the proper area." The light itself could be fastened to the miner's hat, and a flexible cord connected the battery and the lamp.

		By this time he had discovered the principle on which the safety lamp was to be constructed but it was another month or so before he conceived the idea of surrounding the flame of the lamp with wire gauze.
		The first Davy safety lamps were complete at the end of 1815 or early 1816 and sent to John Buddle.
		In practice Davy's lamp was far more significant because it was his understanding of the scientific principles and application of the wire gauze that was so valuable and which formed the basis for the design of virtually all flame safety lamps.
