This culture of safety is also supported by the Clinical and Laboratory Standards Institute ( 2). Should any of the guidelines provided herein conflict with federal, state, or local laws or regulatory requirements, the laboratorian should defer to the federal, state, or local requirements. This document was written not to replace existing biosafety guidelines, but to 1) improve the safety of activities in clinical diagnostic laboratories, 2) encourage laboratory workers to think about safety issues they might not previously have considered or addressed, and 3) encourage laboratorians to create and foster a culture of safety in their laboratories. This report offers guidance and recommends biosafety practices specifically for human and animal clinical diagnostic laboratories and is intended to supplement the 5th edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL-5), developed by CDC and the National Institutes of Health ( 1). Introduction: A Culture of Safety for Diagnostic Laboratories Recommendations for all laboratories include use of Class IIA2 biological safety cabinets that are inspected annually frequent hand washing use of appropriate disinfectants, including 1:10 dilutions of household bleach dependence on risk assessments for many activities development of written safety protocols that address the risks of chemicals in the laboratory the need for negative airflow into the laboratory areas of the laboratory in which use of gloves is optional or is recommended and the national need for a central site for surveillance and nonpunitive reporting of laboratory incidents/exposures, injuries, and infections. A specific section for veterinary diagnostic laboratories addresses the veterinary issues not shared by other human laboratory departments. All functions of the human and animal diagnostic laboratory - microbiology, chemistry, hematology, and pathology with autopsy and necropsy guidance - are addressed. Because many of the same diagnostic techniques are used in human and animal diagnostic laboratories, the text is presented with this in mind. Throughout these guidelines, quality laboratory science is reinforced by a common-sense approach to biosafety in day-to-day activities. They are not requirements but recommendations that represent current science and sound judgment that can foster a safe working environment for all laboratorians. These guidelines promote a culture of safety and include recommendations that supplement BMBL-5 by addressing the unique needs of the diagnostic laboratory. The members of this panel recommended that biosafety guidelines be developed to address the unique operational needs of the diagnostic laboratory community and that they be science based and made available broadly. In 2008, CDC convened a Blue Ribbon Panel of laboratory representatives from a variety of agencies, laboratory organizations, and facilities to review laboratory biosafety in diagnostic laboratories. BMBL-5, however, was not designed to address the day-to-day operations of diagnostic laboratories in human and animal medicine. CDC and the National Institutes of Health addressed the topic in their publication Biosafety in Microbiological and Biomedical Laboratories, now in its 5th edition ( BMBL-5). laboratories has been a concern for many years.
