In this lab you will be working with living organisms that may or may not be considered living organisms, therefore, all microbes should be treated as a potential pathogen. • You must adhere to strict lab safety guidelines to ensure the safety of yourself, your classmates, and your family and friends at home.
Biosafety Levels (BSL) • BSL 1 - BSL-1 is appropriate for working with microorganisms that are not known to cause disease in healthy human humans. This is the type of laboratory found in municipal water-testing laboratories, in high schools, and in some community colleges teaching introductory microbiology classes, where the agents are not considered hazardous. • BSL 2 - The agents manipulated at BSL-2 are often ones to which the workers have had exposure to in the community, often as children, and to which they have already experienced an immune response. These agents are generally transmissible following ingestion, exposure of mucous membranes, or intra-dermal exposure. Eating, drinking and smoking are prohibited in BSL-2 laboratories, and extreme precautions are taken while handling needles and other sharp instruments. • From “The 123s of Laboratory Biosafety”

Good Practices Label all materials with your name, date, and any other applicable information (e.g., media, organism, etc.). Dispose of wastes in their proper containers. Return all chemicals, reagents, cultures, and glassware to their appropriate places. Observe chemical compatibilities. Do not pour biohazardous fluids down the sink. Glassware should be washed after use and put away All shelves should be labeled and un-cluttered Flame transfer loops, wires, or needles before and immediately after use to transfer biological material. We use live bacteria!
Waste Disposal Prevent exposure to pathogens and hazards: Containers are compatible with waste: Non-contaminated glass :Broken Glass Boxes Contaminated broken glass: Sharps container Soiled but not contaminated gloves, aprons can go in the trash Contaminated gloves, aprons in bio-hazardous waste Bio-hazardous waste: Red bag in biohazard box Needles, lances, blades: Sharps container
