The Garforth – GR6S Mines Approved Flame Safety Lamps

Developed from 125 years experience of saving lives, the Garforth is the ultimate in flame safety lamps. It is the recognised means of methane or firedamp detection in the mines of England and Australia and many other areas of the world. The miners lamps weigh in at 3 3/4lbs and stand 10″ high. 

Flame safety lamps also known as Davy Lamps take their name from the inventor Sir Humphry Davy.

The criteria for miners flame safety lamps were laid down in the Coal Mines Act 1911-Test of Safety Lamps-Memorandum, dated 6th February
1913. The main points were:
1. All lamps must have double gauze’s or arrangement serving the same purpose i.e.
Marsaut and Mueseler lamps acceptable but not Clanny lamps.
2. A straight edge put between the outside of adjacent pillars must not touch the glass this rules out most lamps with only four pillars.
3. Lamps are constructed so that they cannot be assembled without the gauzes.
4. Lamps must have an efficient locking device to prevent removal of oil vessel, glass or bonnet by unauthorised persons. This excludes screw locks.

The GR6S Garforth lamp was developed in the early 1960’s, it is a modified Type 6 lamp. Air samples are taken in an aspirator bulb and injected into the flame to determine the amount of methane present, the system was invented by UK patent 1048136/1964. Manufacture of these lamps started in the late 1960’s and they are still in production today.
The Garforth system bears the name of it’s creator who was a Government Scientist. From the 1960’s to the 1980’s Protector paid a Royalty for the use of the design.

The Garforth system was also installed on Wolf and Thomas & Williams lamps. Both firms also supplied the Ministry of Power which took over the mines on Nationalisation in 1947.
