§ Welding, cutting, soldering; use of fire extinguisher. One portable fire extinguisher shall be provided at each location where welding, cutting, or soldering with arc or flame is performed.

Welding, cutting or soldering with arc or flame in other than a fireproof enclosure shall be done under the supervision of a qualified person who shall make a diligent search for fire during and after such operations and shall, immediately before and during such operations, continuously test for methane with means approved by the Secretary for detecting methane.

The Code of Federal Regulations, 30 CFR § requires the following: “All welding, cutting or soldering with arc or lame in all underground areas of a coal mine shall, whenever practicable, be conducted in ireproof enclosures.

The intentional creation of any open arc, open spark or open flame, except as provided in subsection B, shall be prohibited.

Welding and cutting with arc or flame or soldering underground in other than a fireproof enclosure ventilated with intake air shall be done by or under the direct instruction of a certified foreman or repairman. PART 70 MANDATORY HEALTH STANDARDS FOR UNDERGROUND COAL MINES.

Carbon arc welding: Soldering: 2: Torch brazing: 3 or 4: Light cutting, up to 1 inch: 3 or 4: All arc welding and cutting cables must be of the completely insulated, flexible type, capable of handling the maximum current requirements of the work in progress, taking into account the duty cycle under which the arc welder or cutter is.

One of the predominant causes of fires in underground coal mines is flame cutting and welding. These fires can lead to major events such as the explosion that occurred on Janu in an airshaft being constructed at the McElroy mine.

Gas or oxy-fuel welding uses a flame from burning a gas (usually acetylene) to melt metal at a joint to be welded, and is a common method for welding iron, steel, cast iron, and copper.

Thermit welding uses a chemical reaction to produce intense heat instead of using gas fuel or electric current. Use an electric soldering iron or a gas torch for soft soldering.

Hard Soldering Temperature Hard soldering, sometimes called silver soldering, uses a variety of solder alloys that melt at up to degrees Fahrenheit, to bond a wider variety of metals. Use hand-welding, flame-cutting, hand soldering, and brazing equipment to weld/join metal components, fill holes, indentations, or seams of fabricated metal products.

MSHA revises its rules on sealsJames R. Carroll, Courier-Journal - Partly in response to last year's Darby mine accident in Harlan County, federal regulators yesterday issued strengthened rules governing the walls that seal off abandoned areas of underground mines where explosive and toxic gases can build up.
