The move by the U.S. Mine Safety and Health Administration comes more than six years after the 2006 Sago Mine Disaster, where survivor Randal McCloy said four units failed the 12 miners who died after being trapped deep underground following a powerful explosion.
MSHA and the National Institute for Occupational Safety and Health acted only after a two-year investigation that started in February 2010 when the maker of the devices, Pittsburgh-based CSE Corp., reported an oxygen starter problem similar to that described by McCloy.
Last week, NIOSH issued its long-awaited report of that investigation, confirming a "critical" defect in the oxygen bottles meant to kick-start CSE's SR-100, the mining industry's most widely used model of self-contained self-rescuer, or SCSR.
The phase-out announced by MSHA gives mine operators until Dec. 31, 2013, to replace any and all SR-100 units they have with other models of SCSR approved by the agency.
In a prepared statement, MSHA chief Joe Main defended the nearly two-year timeline for replacing all of the units.
"Due to the large number of CSE SR-100s in underground coal mines, multiple SCSRs available to miners, the low probability of failure and the shortage of immediately available replacements, MSHA and NIOSH have determined that an orderly phase-out will better protect the safety of the miners than immediate withdrawal of the devices," Main said.
Under the MSHA plan, miners who rove around underground -- such as safety examiners or water pumping crewmen who don't have easy access to backup caches of units -- must be given a different model SCSR or a backup SR-100 to wear within 30 days. All other miners must be given new or backup equipment by April 26, 2013, and all SR-100s must be out of the mines by Dec. 31, 2013.
CSE stopped making and selling the SR-100 and last year began marketing a new model of SCSR that the company says is smaller, lighter and produces 40 percent more oxygen than the SR-100, which was rated to supply at least one hour of breathable air.
"We have complete confidence in all of the products we produce and want our customers to know that we are prepared to support their needs during this time of orderly transition and in the future," CSE said in a statement issued Thursday afternoon.
Other SCSR makers include Wisconsin-based Ocenco and the German firm Drager.
Bruce Watzman, vice president for safety issues at the National Mining Association, said his organization was still reviewing the MSHA announcement and had no immediate comment.
