OSHA considers disposable, filtering facepieces (N95, dust masks) to be respirators, and their use is regulated. Employees whose job description requires them to wear respiratory protection must participate in the ISU Respiratory Protection Program. Refer to the ISU Respiratory Protection Manual (PDF) for program details.
Employees who voluntarily use these devices for purposes that are not part of job requirements do not need to participate when the following conditions are true:
- Exposure to airborne contaminants is below OSHA permissible exposure limits (PELs)
- Exposure is only to non-toxic nuisance materials
- A procedure or research protocol does not require use
- Respirators are not worn to reduce exposure to gases or vapors
Voluntary users must follow the use, storage, and disposal guidelines on the Respirators page.
