Use and Care of Microorganisms
This area of science, may involve many dangers and hazards while experimenting. It is the sole responsibility of all teacher(s)/sponsor(s) to teach students proper safety methods and sterile techniques.
Roles and Responsibilities of Students & Adults
The Instructor is responsible for working with the student to evaluate any possible risks involved in order to ensure the health and safety of the student conducting the research and the humans or animals involved in the study.
General Lab Use - Hypochlorite Solutions
The use of a physical or chemical procedure to virtually eliminate all recognized pathogenic microorganisms but not all microbial forms (bacterial endospores) on inanimate objects.
Sterilization: The use of physical or chemical procedures that destroy all microbial life forms, including highly resistant bacterial endospores.
Autoclave: Pressurized steam at 15 psi and 121oC for an average of 20 min (10 – 40 min depending on bulk and load)
