COMPLETE SET OF MINERS' TOOLS. SAFE PRACTICE. Figure 126.-A complete set of miner's tools, with danger board, 5-foot slate Hobar, and "powder box." Study this photograph carefully. You need all these tools to work safely. With them you can dig more coal. The miner wears an electric cap lamp; it gives better light than an oil safety lamp. OIL SAFETY LAMPS AND ELECTRIC CAP LAMPS. DANGEROUS PRACTICE. Figure 129.-Miner carries lamp at his side; helper, who is following, stumbles because he is partly blinded by light from the miner's lamp. Figure 130.-Miner carries lamp in front of body, where it will not shine into the eyes of his helper, who is following him. Miner: Carry your lamp in front of your body when helper follows you. OIL SAFETY LAMPS AND ELECTRIC CAP LAMPS-Continued. Figure 131.-Better still: Miners use permissible electric cap lamps that give better light than oil safety lamps. A permissible electric cap lamp is a lamp that the Federal Bureau of Mines says is safe for use in a coal mine. It gives the best light. Learn to use it; you will have two free hands. Figure 132.-Brattice man, after repairing canvas brattice, carries away tools, but leaves extra battens with nails in them. He uses safety lamp only. He endangers his fellow workmen. Figure 133.-Extra battens are left in roadway; miner comes through opening in brattice curtain, steps on nail, and injures foot. Figure 134.-Brattice man, after repairing brattice, carries away both tools and extra battens. He uses both safety lamp and electric cap lamp. Brattice man: Do not leave in the mine any boards or pieces of waste lumber that have nails in them. 86651°-196 |
