If you are required to wear any respirator related to your work duties or work environment you must follow the requirements of the Respiratory Protection Program. If you are not required but would like to wear a dust mask for comfort or nuisance level protection, you must be approved for voluntary respirator use and receive a review of the contents of Appendix D of OSHA’s respiratory protection standard. This information is available on the EHS website “OSHA Respirator Standard Appendix D with Verification” (https://ehs.psu.edu/respiratory-protection/forms).
