Closed-Circuit Escape Respirators; Extension of Transition Period

In March 2012, the Department of Health and Human Services (HHS) published a final rule establishing a new standard for the certification of closed-circuit escape respirators (CCERs) by the National Institute for Occupational Safety and Health (NIOSH) within the Centers for Disease Control and Prevention (CDC). The new standard was originally designed to take effect over a 3-year transition period. HHS has determined that extending the concluding date for the transition is necessary to allow sufficient time for respirator manufacturers to meet the demands of the mining, maritime, railroad and other industries. Pursuant to this final action, NIOSH extends the phase-in period until 1 year after the date that the first approval is granted to certain CCER models.
