Voluntary disposable respirators without expected overexposure

Summary A state safety official asked about employees wearing disposable dust respirators when chemical overexposure did not exist or was not expected. OSHA said the respiratory-protection standard was not mandated in those circumstances, while recommending that employers consider training and medical surveillance because respirator use can itself cause harm. OSHA now labels the letter an archive document.

Dear Mr. Dinkel:

This is in response to your August 21, letter to the Director of Compliance Programs, requesting clarification of the requirements of the Respiratory Protection Standard, 29 CFR 1910.134, as it pertains to employees wearing disposable dust respirators

Ms. Patricia K. Clark's, March 19, 1991 letter remains basically correct, in that, in situations where an over-exposure to a chemical does not exist and the potential for an over-exposure is not anticipated, the employer is not mandated to comply with the Respiratory Protection Standard. However, it should be noted that in some circumstances adverse health conditions can be caused by the wearing of a respirator. Examples of those circumstances include, but are not limited to, (1) the wearing of a dirty respirator that causes dermatitis, or ingestion of a hazardous chemical; (2) the sharing of a respirator that leads to transmittal of disease; (3) an employee's health being jeopardized by the wearing of a respirator (e.g., employee has a cardiac and/or pulmonary disorder). Therefore, it is recommended that training and medical surveillance be considered for all employees who may elect to use a respirator for personal comfort.

We appreciate the opportunity to clarify this matter for you. If you have any further questions, please feel free to contact OSHA's Office of Health Compliance Assistance at (202) 219-8036.

Sincerely,
John B. Miles, Jr., Director
Directorate of Compliance Programs
