Subject: Revocation of all Respirator Certificates of Approval Issued to Dual Safe Life (DSL) Effective August 30, 2009.

At the request of Dual Safe Life (DSL), The National Institute for Occupational Safety and Health (NIOSH) has revoked the following certificates of approval:


As of August 30, 2009, no DSL respirator model can be listed as NIOSH approved.

NIOSH has revoked these approvals pursuant to the manufacturer’s request. The manufacturer has ceased production and maintenance of the above respirators. Consequently, there is no longer a quality control system in place and the revocation is in accordance with the authority granted in Title 42, Code of Federal Regulations, Part 84.43(c)(42 CFR 84) which states “The Institute reserves the right to revoke, for cause, any certificate of approval where it is found that the applicant’s quality control test methods, equipment, or records do not ensure effective quality control over the respirator for which approval was issued” and the authority granted in 42 CFR 84.34 which states “The Institute reserves the right to revoke, for cause, any certificate of approval issued pursuant to the provisions of this part. Such causes include, but are not limited to, misuse of approval labels and markings, misleading advertising, and failure to maintain or cause to be maintained the quality control requirements of the certificate of approval.
