Dear Ms. Mullaney:

This is in response to your letter of January 20, requesting Occupational Safety and Health Administration (OSHA) guidance on the wearing of gloves when handling unopened specimen containers. We apologize for the delay in this response.

The personal protective equipment (PPE) requirements in 29 CFR 1910.1030, "Occupational Exposure to Bloodborne Pathogens", are performance oriented. The standard requires that the type and amount of PPE be chosen to protect against contact with blood or other potentially infectious materials based upon the type of exposure and quantity of these substances which can be reasonably anticipated to be encountered during the performance of a task or procedure.

For example, gloves must be worn when it can be reasonably anticipated that the employee may have hand contact with blood or other potentially infectious materials and when handling or touching contaminated items or surfaces.

Your question concerns the handling of specimen containers which contain sera. Because sera is clear, contamination of the containers would not necessarily be visible. We therefore agree with you that gloving is appropriate when handling these containers within the laboratory, although not necessarily required by the standard. When outside contamination of the primary container is suspected or likely to occur, they must be placed in secondary containers which would prevent leakage. This would negate the need for all employees who contact them to don gloves.

We hope this information is responsive to your concerns. Thank you for your interest in worker safety and health.

Sincerely,



Patricia K. Clark, Director
Directorate of Compliance Programs
