A safety lamp is any of several types of lamp that provides illumination in coal mines and is designed to operate in air that may contain coal dust or gases both of which are potentially flammable or explosive. Until the development of effective electric lamps in the early 1900s miners used flame lamps to provide illumination. Open flame lamps could ignite flammable gases which collected in mines, causing explosions and so safety lamps were developed to enclose the flame and prevent it from igniting the surrounding atmosphere. Flame safety lamps have been replaced in mining with sealed explosion-proof electric lights.
Miners have traditionally referred to the various gases encountered during mining as damps, from the Middle Low German word dampf (meaning "vapour"). Damps are variable mixtures and are historic terms.

This clip is from the training film, Koehler & Wolf Permissible Flame Safety Lamps, produced about 1973 by the US Mining Enforcement and Safety Administration (MESA). The film was used to train mine safety men about oxygen deficiency and provide a working knowledge of the flame safety lamp used to detect methane and oxygen deficiency. Prior to the invention of safety lamps, miners used candles with open flames. The use of small mammals or birds was used much later to warn of the presence of the deadly carbon monoxide present after underground fires or explosions, the so-called afterdamp. Such animals are much more susceptible to the gas, and will die before a human, so giving an early warning of the problem. The lack of good lighting was a prime cause of a painful eye affliction (nystag...

The STS Seminar series continues with a fascinating talk from Prof. Sharon Ruston (Lancaster University). Over the course of an hour, she discusses the dispute over the invention of the miner's safety lamp, and the input and debate from Davy, Stephenson and Clanny into the various forms of lamp produced.
Frank James showcases' Humphry Davy's experimental development of his miners' safety lamp, that saved thousands of lives. Watch our short film about the Davy lamp: https://youtu.be/rhavaxv3a40 Watch the Q&A; here: https://www.youtube.com/watch?v=2i22r058GC0 One of the last acts of Tsar Alexander I before his death in 1825 was to give Humphry Davy a silver-gilt cup — the Davy cup. It was a token of gratitude for Davy’s invention of the miners’ safety lamp ten years before. With appropriately explosive demonstrations, Frank James showcases Davy’s experimental development of his lamp while reflecting on the relationship between science and the state symbolised by the Davy cup, a treasure from the Ri's Faraday Museum.

Speaker: Professor Frank James UCL Science and Technology Studies This year marks the bicentenary of the deployment of the safety lamp, invented by Hmphry Davy. Its remarkable success has tended to mask Davy's practical failures, including a diplomatic incident over unrolling the Heculaneum papyri and the disabling of the Royal Navy. Join Professor Frank James as he explains the difficulty of applying science successfully.
This is how I shot and edited the photos to create a star trail in Photoshop. Resources: http://www.psdbox.com/?p=8442 We will visit the location before the night shooting session in order to see the access and possible setup places. Versión española: https://www.youtube.com/watch?v=vAj1urYyGRw I will also show you how to shoot time lapse photography, the camera settings and how I took the dark frame used to subtract the noise from the image once the star effect is created in Photoshop.

A short history of the engineering and scientific force put to work to save lives underground, focussing particularly on the work of Sir Humphry Davy and George Stephenson: http://www.gresham.ac.uk/lectures-and-events/safety-underground-mining-and-the-miners-lamp Mining disasters such as those at High Blantyre in 1877 or Gresford (1934) are a reminder of the hazards of mining. Work done by Sir Humphry Davy and George Stephenson on the safety lamp will be used to illustrate the problems of taking scientific knowledge out of the controlled environments of the laboratory and putting it to practice use. The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and-events/safety-underground-mining-and-the-miners...
This is one of those projects that is not only fun and therapeutic to do, but gives you a really versatile set of lights for life. You can support this channel at https://www.patreon.com/bigclive I've covered this style of project before, but it's a great one, so worth covering again. This project is really intended for the short 20 lamp tungsten strings common in the UK and some other countries. It can be upscaled slightly depending on your mains voltage with a change of resistor value and increasing 100/120Hz flicker with higher numbers of LEDs. 20 is the simplest though. The LEDs are deliberately run at very low current (around 3mA) for use as subtle background decoration. You can mix and match LEDs to your hearts content. Keep in mind that the LEDs are still operating at mains vol...

The "lights" can be seen beginning at approximately 23min 18seconds (@ 2122hrs) Most of my viewers know where I stand on the Yellowstone issue. I personally feel we are NOT looking at an eruption threat, rather - watch out for possible greater earthquake activity in the near term. Possibly a swarm , or could be a single larger seismic event. This video is the whole day of February 23 beginning at approximately 6am MST -- spanning 24 hours to 6am February 24 2015. For a full half day, the geyser basin surrounding Old Faithful shows some very heavy activity -- which is then followed at night by strange white, green, yellow, and red lights. As a comparison for the geyser activity, here is a comparison of a normal day from this past week (the 19th) vs. Yesterday (steam from geysers sh...
