NIOSH Rescinds Respirator Approval Issued to Merilogy

NIOSH announced in a recent notice that it has honored the request of Merilogy Inc. to voluntarily rescind one of its respirator approvals. As of Aug. 16, respirators bearing the approval number TC-84A-9294 are no longer approved by NIOSH and may no longer be used, manufactured, assembled, sold, or distributed. The agency directs individuals to contact Merilogy regarding inquiries about the decision to voluntarily rescind this approval.

NIOSH’s certified equipment list no longer includes the approval number TC-84A-9294. 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 Laboratory provides a list of additional guidance documents intended to inform users of respiratory protective devices.
