The Occupational Safety and Health Administration today announced updated inspection procedures related to worker exposures to tuberculosis in health care settings. According to the agency, the directive incorporates 2005 guidance from the Centers for Disease Control and Prevention, and covers additional workplaces regarded as health care settings, such as sites where emergency medical services are provided and laboratories handling clinical specimens. It also introduces a newer screening method for analyzing blood; classifies health care settings by risk; and reduces the frequency of TB screenings for workers in some settings, the agency said.
