Dear Ms. Stude:

This is in response to your letter of August 27, 1992, and will serve as written confirmation to information provided to you by phone from this office. We apologize for the delay in this written response.

The U.S. Environmental Protection Agency is the governmental agency which is responsible for overseeing the registration of sterilants, tuberculocidal disinfectants, and anti-microbial products. A list of registered products may be obtained by contacting their anti-microbial hotline at (800) 447-6349. Under 29 CFR 1910.1030, the Occupational Exposure to Bloodborne Pathogens standard, the Occupational Safety and Health Administration (OSHA) requires that contaminated items and surfaces be decontaminated with an appropriate disinfectant. EPA-registered tuberculocidal disinfectants and solutions of 5.25 sodium hypochlorite (household bleach) diluted between 1:10 and 1:100 with water are considered appropriate for this purpose.

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

Sincerely,



Roger A. Clark,
Director
Directorate of Compliance Programs
