law, US employers must establish a written respiratory protection program meeting the requirements of
the OSHA Respiratory Protection Standard 29 CFR 1910.134 and any applicable OSHA substance specic
standards. For additional information on this standard contact OSHA at www.OSHA.gov. In Canada, CSA

W WARNING
1. These products meet the requirements of certain industrial eyewear standards and with some
models, certain industrial head protection standards. They do not provide complete head, eye,
and face protection from severe impact and penetration and are not a substitute for good safety
practices and engineering controls. Misuse may result in serious injury or death. For proper
use, see supervisor, refer to the product User Instructions or contact 3M Technical Service.
2. When exposed to eye and face hazards, wear additional eye and/or face protectors appropriate to
the hazard. ANSI Z87.1-2010, incorporated by reference in the OSHA Eye and Face Standard 29
