Guidelines for Biosafety Laboratory Competency --- CDC and the Association of Public Health Laboratories

These guidelines for biosafety laboratory competency outline the essential skills, knowledge, and abilities required for working with biologic agents at the three highest biosafety levels (BSLs) (levels 2, 3, and 4). The competencies are tiered to a worker’s experience at three levels: entry level, midlevel (experienced), and senior level (supervisory or managerial positions). These guidelines are intended for laboratorians working with hazardous biologic agents, obtained from either samples or specimens that are maintained and manipulated in clinical, environmental, public health, academic, and research laboratories.
