NIOSH CA 2023-1065
September 2023

The National Institute for Occupational Safety and Health (NIOSH) has honored a request by Walter Surface Technologies to voluntarily rescind three NIOSH respirator approvals issued to Walter Surface Technologies. 

As of September 29, 2023, any respirator marked with a NIOSH approval label with approval numbers TC-21C-0815, TC-21C-0838, and TC-21C-0881 are no longer approved by NIOSH. The NIOSH Certified Equipment List no longer includes these approval numbers.

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

Please reach out to Walter Surface Technologies for additional details related to their decision to voluntarily rescind three approvals issued to Walter Surface Technologies identified in this notice. The Certified Equipment List can be used to locate other NIOSH Approved® respirators.

NIOSH Approved® is a certification mark of the U.S. Department of Health and Human Services (HHS) registered in the United States and several international jurisdictions
