Historical NotesUsed at local mines to detect low pressure that can create dangerous conditions in mines. Toxic and explosive gases more prevalent. This French-made model of the early 1900s was found in the office of the Bureau of Mines.Label TextSome speculated that mine disasters occurred in winter months due to low barometric pressure, which allowed toxic and explosive gases to escape from seams in the coal bed. Barometers, therefore, were used by mine safety officials to monitor the pressure. This French-made model of the early 1900s was found in an office of the Bureau of Mines. Mining engineer Gene Palowitch entered many Western Pennsylvania coal mines for inspection duties and had to be constantly prepared for cave-ins and toxic gases. Barometer, a standard piece of mining equipment to monitor barometric pressure, as low pressure allows for toxic and explosive gases to escape from seams in the coal bed. This French-made model of the early 1900s was found in the office of the Bureau of Mines.
