City University of New York (CUNY) reviews and authorizes research with biological materials such as microorganisms, viruses, and animal or human tissue.  EHOS assists with this review process by inspecting CCNY laboratories for compliance with the guidelines published by the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) in the Biosafety in Microbiological and Biomedical Laboratories (BMBL) and Primary Containment for Biohazards: Selection, Installation, and Use of Bios Cabinets.  These guidelines are set forth by the CDC’s Office of Safety, Health, and Environment and the NIH periodically to promote the safety and health of workers in biological and medical laboratories.  These national publications are periodically updated and are both available as free PDFs.
