MSHA reopens mine-respirator comments through December 8 and schedules a November hearing
An October 16 notice reopens comments on MSHA's proposed use of specified powered air-purifying respirators in underground gassy mines. A virtual hearing begins November 17 at 9 a.m. Eastern; advance speaker registration is requested by November 13. Written comments close December 8 at 11:59 p.m. Eastern. The notice changes the participation window, not the equipment's current approval status.

A record appears here because it carries respirators in its own tags. If a record you expected is missing, it was filed under a different subject — the full list is on the topics index.
