How many biosafety levels (BSLs) are there?

A collection of safeguards restricted to autoclave-related activities in specific biological labs. They are personal protections intended to protect laboratory staff as well as the local environment and community.

If you work in a ______, the microbes there are not known to reliably cause disease in healthy adults and pose little risk to laboratorians and the community. A microbe that is commonly worked with at a _____ level is a strain of E. coli that is not pathogenic.

_____ builds upon BSL-1. If you work in a lab that is designated a ____, the microbes there pose moderate hazards to laboratorians and the environment. The microbes are typically indigenous and associated with diseases of varying severity. An example of a microbe that is typically worked with at a _____ laboratory is Staphylococcus aureus.

_______ is simply a recipe, or written design, for performing the experiment. You must write a protocol to insure that you have both a clear idea of how you will do the experiment and that you will have all the materials that are needed.

The aim of the ___________ is to evaluate hazards, then remove that hazard or minimize the level of its risk by adding control measures, as necessary. By doing so, you have created a safer and healthier workplace.
