Safety Update: NIOSH Rescinds Respirator Approval

The National Institute for Occupational Safety and Health (NIOSH) has honored a request by Honeywell International Inc. to voluntarily rescind the NIOSH respirator approval issued to Honeywell International Inc. Read CA 2023-1060.

As of June 29, 2023, any respirator marked with a NIOSH approval label with approval number TC-84A-9263 is no longer NIOSH approved. The NIOSH Certified Equipment List no longer includes this approval number.

Due to the voluntary rescission of this NIOSH approval, respirators bearing this NIOSH approval number may no longer be used, manufactured, assembled, sold, or distributed.

Please reach out to Honeywell International Inc. for additional details related to their decision to voluntarily rescind the approval issued to Honeywell International Inc. identified in this notice. The NIOSH Certified Equipment List can be used to locate other NIOSH Approved respirators.

“Many companies will not care to update our members,” said IAM Director of Safety & Health, Apprenticeships and Scholarships Michael Oathout. “Some have to take responsibility for their own safety and we are here to assist.”

Any questions or guidance needed, please reach out to the Safety and Health Department at 301-967-4704 or
