Microbiology Laboratory Safety Rules and Procedure

Safety in a microbiology laboratory is important in the prevention of infection as Microbiology laboratory cultures, manipulates, and uses virulent and/or potentially pathogenic microorganisms.  In addition to microorganisms, there are some chemicals used in this laboratory that are potentially harmful. Many procedures involve glassware, open flames, and sharp objects that can cause trauma/ damage if used improperly.
