On March 8, 1924, in Castle Gate, Utah, two explosions rocked the local coal mine, killing all 171 men working at the time. Both explosions happened when men ignited carbon monoxide while trying to relight their lamps. First, a boss investigating some methane gas near the roof of a mineshaft. When his lamp went out, he tried to relight it, but his match ignited the gas, which in turn ignited coal dust, setting off a huge explosion. Those who survived this first explosion found themselves plunged into darkness, as the blast blew out their lamps. When these survivors attempted relighting their lamps, they set off another explosion.
Rescue workers faced severe challenges when they entered the mine to look for any possible survivors. The passageway was covered with debris and badly damaged. It made the passageway incredibly difficult to traverse and slowed them down. The mine was also filled with gas, which made it deadly for the rescue workers. One rescuer died when another knocked off his oxygen clip; within a few minutes, he breathed in too much gas and perished. When the workers found the bodies, many were badly burned and mutilated. Because of huge number of deaths, bodies were buried soon after identification.
Most of the men were married with children, leaving behind many widows and children without fathers. In the days after the disaster, the Red Cross along with women from other parts of came to offer aid to the families. They cooked meals, tended to children, and even sewed mourning clothes for the community. The families of the miners were devastated; in addition to losing a husband and father, they also lost their primary financial provider. Although the families did receive compensation, many left Castle Gate to go live with relatives. Those who stayed received aid from a Red Cross committee that provided food, clothes, and anything else the families might need. The relief committee continued to distribute aid until 1936, ultimately dispersing $132,145 worth of relief.
The mine eventually reopened with increased safety measures. The Utah Fuel Company, which owned the mine, met with the state government to review safety laws and create new amendments and resolutions to make the mines safer. This included more funding for mine inspectors, mandates about clearing dust created from rock mining, prohibiting moving methane gas while men were working in the mine, and requiring coal dust be cleaned from abandoned rooms. Though these new procedures did not completely stop other disasters, they did greatly improve the safety of the mines.
