Pre-lab Questions
1. In this course, you will utilize several types of growth media to observe the nature of
microorganisms. How can you protect yourself from any microorganisms that you may work with in the
upcoming labs?
I can protect myself from microbes by using gloves and safety eyewear. I will also diligently practice good
hand hygiene by fully cleaning my hands both before and after participating in any experiments. To reduce
the possibility of microbiological contamination and provide a secure laboratory environment, this
preventive measure is crucial.
2. What constitutes personal protective equipment? When should personal protective equipment be worn?
Personal Protective Equipment (PPE) is meant to reduce the chance of exposure to several types of
potential hazards. This covers, among other things, respirators, hard helmets, eye protection, gloves, boots,
earmuffs, and full-body suits. Proper personal protective equipment (PPE) is essential when handling
substances like blood, respiratory secretions, and body fluids or when confronted with possible chemical or
biological threats. People's safety in situations where these risks exist is ensured by using personal
protective equipment (PPE).

3. What is meant by “BioSafety Levels”? Why do researchers utilize these when working with microorganisms?
What level of biological containment (which BSL) will be necessary to complete the experiments in this
course?
A series of biocontainment measures known as "biosafety levels" are necessary to separate
potentially harmful biological agents inside a lab building. This helps researchers determine
what safety precautions are required in a laboratory to safeguard the environment and the workers. BSL-
1 is the BSL level that will be needed to finish the trials.
4. What document should you refer to if you have questions regarding the safety or disposal of a chemical?
Where can this document be located?
Refer to the Safety Data Sheets (SDS), which are available online at the Environmental Health
