Carrying out research for the purpose of prophylactic medicine with dangerous, highly infectious causative agents of disease requires appropriate safety conditions. In addition, the need for appropriate biological safety and security considerations is acquiring an ever-growing national and international importance given the existing threat of the use of these agents by terrorists. Because of these facts, the harmonization of national safety guidelines regulating the organization and work with Hazard Group I-IV pathogens in different countries is gaining more importance and relevance. This paper presents a comparative analysis of safety guidelines and regulations from the United States contained in the Centers for Disease Control and Prevention-National Institutes of Health Biosafety in Microbiological and Biomedical Laboratories (BMBL), the World Health Organization Laboratory Biosafety Manual (WHO LBM) and Russia's Sanitary Rules (SRs).
