State now moving on mine shelters


The protocol details a 96-hour test during which NIOSH will measure the interior atmosphere of each refuge chamber.

“We will be testing the breathable atmosphere, whether these units are capable of creating a breathable environment for 96 hours,” Bauer said. “That includes CO2 scrubbing, (oxygen) and heat and humidity.”

West Virginia law requires that all approved shelters be able to sustain life for 96 hours. Bauer said NIOSH can simulate human occupancy in the shelters to determine how factors such as metabolic heat production affect the interior atmosphere. Scientists also will measure heat transfer through shelter walls.

Possible Human Testing

NIOSH also is working on a protocol for human testing, according to Dr. Jeffrey Kohler, director for mine safety and health research at NIOSH.

“For the last three to four weeks, we’ve have a team look at developing a protocol for human tests — a pulmonary physician, a general physician, psychologist, physiologist, engineers and other scientists — to determine the value of human subject testing versus a simulation,” Kohler said.

Even though many individuals such as O’Dell have stepped forward and volunteered to be test subjects, Kohler said NIOSH must comply with strict federal regulations controlling human testing. A private company that does not have federal funding would not have that hurdle, he said, but NIOSH does.

O’Dell said he fully supports additional mine shelter testing.

“If they want to do it, they’ve got plenty of volunteers out there,” he said. “If that’s necessary, and if it means a delay (in implementation) to afford the best protection for our miners, then that’s what we need to do.”

O’Dell said he also would not oppose a delay in West Virginia’s timeline to wait for NIOSH to finish its first round of testing.

“A month of additional tests would be a whole lot better than sticking these things underground and finding out they’re going to fail,” he said. “Everyone seems satisfied to move forward, but if there are experts out there who believe there is a problem, they need to step up to the plate and tell us. ... We don’t want to put the health and safety of miners at risk.”
