NIOSH Revokes One Respirator Approval, Rescinds Another
NIOSH announced this month that it has revoked the respirator approval issued to LiveFree Personal Protection LLP and has honored the request of another company, RB Sigma LLC, to voluntarily rescind the NIOSH respirator approval issued to it.
As of March 1, any LiveFree Personal Protection LLP respirator marked with a NIOSH approval label with the number TC-84A-9293 is no longer approved by NIOSH, the agency explains in a notice published on its website. Respirators bearing this revoked NIOSH approval number may no longer be used, manufactured, assembled, sold, or distributed. The agency’s notice directs individuals to contact LiveFree Personal Protection LLP for details related to the revocation of this NIOSH respirator approval.
The voluntary rescission of the NIOSH respirator approval issued to RB Sigma LLC affects respirators marked with the approval number TC-84A-9419. As of Feb. 15, respirators bearing this number are no longer NIOSH approved and may no longer be used, manufactured, assembled, sold, or distributed, according to a notice on the NIOSH website. The agency directs individuals to contact RB Sigma LLC regarding inquiries about the decision to voluntarily rescind this approval.
NIOSH’s certified equipment list no longer includes the approval numbers TC-84A-9293 and TC-84A-9419. The agency encourages respirator users and others to use this list to confirm testing and certification approval numbers, which are printed on NIOSH-approved respirators. The website of the agency’s National Personal Protective Technology Equipment Laboratory provides a list of additional guidance documents intended to inform users of respiratory protective devices.
