Could rescue chambers have saved West Virginia miners?

Mine rescue chambers have been required since 2006, even though federal authorities could have required them as far back as 1969. But it's still unclear whether miners in this week's explosion in West Virginia could have reached the chambers.

Mourners arrive for the funeral of miner Steven "Smiley" Harrah, 40, in Shady Spring, West Virginia, on Friday. Harrah is one of 25 known to have died after an explosion in Upper Big Branch Mine in Montcoal, West Virginia. Four miners remain unaccounted for.

Monday’s explosion at a West Virginia coal mine is becoming a possible test case for the benefit of rescue chambers, which federal legislators mandated all mine operators have installed four years ago to save lives underground in case disaster strikes.

“Mines in this country really haven’t been tested. This is the first test where chambers had been installed,” says Patrick McGinley, a professor of law at West Virginia University who enforced mine safety laws in Pennsylvania as a former special assistant attorney general.

Rescue workers at the Upper Big Branch South Mine in Whitesville have been trying all week to reach two such chambers with hopes of saving four missing miners. An explosion Monday afternoon killed 25 miners and hospitalized two others, in what is considered the worst mining disaster in 25 years.

The chambers are airtight safe houses that provide four days of clean air for up to 15 people, as well as a supply of food and water, communication and toilet facilities. They are located within 1,000 feet of worker areas and are spaced no more than 30 minutes apart.

Rescue crews were within 500 feet of one chamber Thursday but were ordered back when it was discovered the air was contaminated with high levels of carbon monoxide, methane, and hydrogen gases. A second attempt Friday was similarly stalled due to a fire underway near the chamber.

However, officials from the US Mine Safety and Health Administration (MSHA) said it was determined the first chamber was not deployed and a camera was inserted into the mine to find out the status of the second chamber.

'A sliver of hope'

“We’ve all got one opportunity, a sliver of hope, a miracle if you will, if the other chamber has been deployed, then we have chance,” Kevin Stricklin, a MSHA official, said Friday.

Rescue chambers were not required in mines until the 2006 Mine Improvement and New Emergency Response Act (MINER), a federal mandate that firmed up safety measures in mines as well as emergency response measures such as wireless tracking systems, clearly marked escape routes, and self-rescuing breathing devices.

But safety advocates in the mining industry complain that MSHA was given full authority to require mine operators to install rescue chambers as far back as 1969 when Congress passed the Federal Coal Mine Health and Safety Act, considered a landmark piece of legislation in how comprehensive it was in dealing with safety and health issues. A provision in the law gave MSHA permission to enforce the use of the chambers, but did not rule it mandatory.
