Sago Mine Disaster - Rescue

Rescue

It was reported that the early hours after the blast were chaotic and the mining company did not call a specialized mine rescue crew until 8:04 a.m. — more than 90 minutes after the blast. The company notified the Federal Mine Safety and Health Administration (MSHA) at 8:30. The company said it started its calls at 7:40. MSHA records two calls at 8:10 to personnel who were out of town due to the holiday. MSHA arrived on site at approximately 10:30 am. The first rescue crew arrived ten minutes later.

High levels of carbon monoxide (CO) and methane gas in the mine atmosphere made it necessary for rescuers to wait 12 hours after the explosion to begin to reach the miners. Tests taken through holes drilled from the surface showed that the air near where the miners were last known to be stationed contained 1,300 parts per million of CO. More than 200 parts per million is considered unsafe. However, each miner had a Self-Contained Self-Rescuer (SCSR) device that provided one hour of breathable air. Emergency supplies were stored in 55-gallon drums (205 L drums) within the mine.

Even after the gases abated, rescue teams had to proceed with caution, continually testing for hazards such as water seeps, explosive gas concentrations, and unsafe roof conditions. This limited their rate of progress to 1,000 feet (300 m) an hour. They checked in every 500 feet (150 m), and then disconnected their telephones until the next checkpoint in order to avoid the possibility of a spark creating another explosion. MSHA had deployed a 1,300-lb. (520 kg) robot into the mine as well, but pulled it out after it became mired 2,600 feet (790 m) from the mine entrance.

After more than nine hours of searching, rescue teams pulled out of the mine at about 3:40 a.m. Tuesday, January 3. Through an agency spokeswoman, Bob Friend of MSHA said the teams were withdrawn when they discovered that the mine's atmospheric monitoring system was still running. Due to the air quality in the mine, power to the system could have caused another explosion according to safety experts. Also, a borehole being drilled to check the mine's air quality was nearing the mine roof. "The bit and steel being used was not equipped to use water, which meant the bit was hot and could ignite an explosive mixture of methane," Friend told a reporter from the West Virginia Gazette. Rescue teams returned to the mine 6:22 a.m.

Famous quotes containing the word rescue:

    To rescue our children we will have to let them save us from the power we embody: we will have to trust the very difference that they forever personify. And we will have to allow them the choice, without fear of death: that they may come and do likewise or that they may come and that we will follow them, that a little child will lead us back to the child we will always be, vulnerable and wanting and hurting for love and for beauty.
    June Jordan (b. 1939)

    In the event of an oxygen shortage on airplanes, mothers of young children are always reminded to put on their own oxygen mask first, to better assist the children with theirs. The same tactic is necessary on terra firma. There’s no way of sustaining our children if we don’t first rescue ourselves. I don’t call that selfish behavior. I call it love.
    Joyce Maynard (20th century)

    Here I pause in my sojourning, giving thanks for having come,
    come to trust, at every turning, God will guide me safely home.
    Jesus sought me when a stranger, wandering from the fold of God,
    Came to rescue me from danger, precious presence, precious blood.
    Robert Robinson (1735–1790)
