On November 6, 1910, an explosion kills 16 coal miners in the Pacific Coast Co. Lawson Mine at Black Diamond, located in eastern King County. Because the slope caved in on the miners, five of their bodies were never recovered. The cause of the accident could not be determined.
The dead were identified as follows:

Rescuers used four of the new Draeger oxygen units supplied by the Mine Rescue Station at the University of Washington. The Mine Rescue Station was established with contributions from mines in Washington in March 1910 after a demonstration of the equipment at the 1909 Alaska-Yukon-Pacific Exposition. The station trained mine workers to use the equipment in smoke and gas filled mine tunnels.
The Inspector of Coal Mines reported that although the number of fatalities had increased, the following improvements to the industry had taken effect:
- a law raising the minimum age for underground workers from 14 to 16;
- a law raising the minimum age for outside workers from 12 to 14;
- an eight hour work day.
