Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Permissible Electric Lamps for Miners Portable electric mine lamps have been used in the United States for at least 5 years and in Europe for nearly 15 years, so that such lamps can not be considered as untried novelties. The last 12 months have been marked by more than usual activity in the development and use of such lamps; several new patterns have been put on the market; other patterns are being developed; old models have been improved; and much interest in the performance of the lamps has been shown by mine operators. Reports from mines where the lamps are being tried indicate that the men prefer portable electric lamps to safety lamps, and in at least one State the use of portable electric lamps in coal mines has been authorized by law. Therefore it seems reasonable to believe that the movement toward a general adoption of portable electric lamps, especially in gaseous mines, has begun and that the number in use will gradually increase.
