flame safety lamp

Firedamp detection was by means of a flame safety lamp.

The wand of science: a history of the British flame safety lamp.

Flame safety lamps have been replaced in mining with sealed explosion-proof electric lights.

The flame safety lamps in use today are all based on Sir Humphrey Davy's principle.

The pellistor was developed in the early 1960s for use in mining operations as the successor of the flame safety lamp and the canary.

Most notable is one of the largest collections in the United States of flame safety lamps of over 100 different makes and styles.

Flame Safety Lamp which is used for firedamp testing in all UK coal mines.

Our flame safety lamp was extinguished in Pearl Chamber when it was placed on the floor as we waited for others to descend.

By 1886 a lamp with better light output than a flame safety lamp was in production by the Edison-Swan Company.

These required Mine Deputies to undertake statutory examinations and to carry flame safety lamps and gas detectors during inspections.

Instead of a canary, early miners used a flame safety lamp, a small lamp that used a wick to burn naphtha fuel.

Its presence is detected in mines by the effect of reduced oxygen on the luminosity of the flame of a flame safety lamp.

Objects on display included early oil lamps, enclosed-flame lamps, carbide lights, battery-powered cap lamps, and the flame safety lamp.

The height of the cone of burning methane in a flame safety lamp can be used to estimate the concentration of the gas in the local atmosphere.

A modern-day equivalent of the Davy lamp is the Protector Garforth GR6S flame safety lamp which is used for firedamp testing in all UK coal mines.

An early safety measure, by no means universal for many years, was the locked flame safety lamp, which was first used as the sole lighting source in the Metropolitan Colliery in NSW in 1897.

Although its use as a light source was superseded by electric lighting, the flame safety lamp has continued to be used in mines to detect methane and blackdamp, although many modern mines now also use sophisticated electronic gas detectors for this purpose.

His description of the way a flame safety lamp can be used to detect firedamp by the increase in height of the flame, and chokedamp by the dying of the flame, is a classic exposition in his textbook, Respiration.

The collections of what is now the Royce J. and Caroline B. Watts Museum, began prior to the establishment of the School of Mines, later named COMER, at West Virginia University in 1930 with the collection of flame safety lamps.
