Who remembers clocks like this?












ReadiMasks are no longer NIOSH approved. And haven't been for over a year. Voluntary Rescission of ReadiMask's NIOSH approval was granted March 25, 2025 at the request of Global Safety First, LLC. This applies to both the small N1901S and the large N1901L models currently sold on ReadiMask dot com under the no longer valid TC-84A-8133 approval number. ReadiMask continue to claim NIOSH approval on their website homepage and elsewhere. However, ReadiMask quietly memory holed their 2019 NIOSH approval letter that they used to link to on their website's disclaimer page. And their link to the NIOSH approval on the CDC website is now 404. It’s unknown at this time why GSF requested the voluntary rescission. It’s common for companies discontinuing a single model of respirator, or for companies getting out of the respirator market entirely to request a rescission. It's possible they are working on a replacement, such as the ReadiMask365 announced in 2022, but they haven't made any announcements about that mask since then. The rescission does not necessarily mean the unapproved masks are bad, but they no longer qualify as OSHA compliant for workplace use.
