Biohazard Level 1 usually includes viruses and bacteria like Escherichia coli and chickenpox and many non-infectious bacteria. The level of precaution at this level is minimal and usually involves wearing a face mask and no close contact.

Pathogenic E. coli strains are not exempt from the NIH Guidelines (NIH Guidelines III-D). For these strains Biosafety Level 2 (BL2) physical containment conditions are required. The Institutional Biosafety Committee can specify higher containment if deemed necessary.

Animal Vivarium Guidance
Animal Housing Biosafety Level (ABSL): ABSL-2 Animal Biosecurity: Experimental animals are housed separately Perform Inoculations: In a Biosafety Cabinet Change Cages: In a Biosafety Cabinet
Health Hazards
Signs and symptoms of infection may include:.
1) Gastrointestinal symptoms (i.e. loss of appetite, nausea, vomiting, diarrhea) Immunizations: None available Prophylaxis*: Available *Formal medical advice is obtained during medical consultations with Cornell Healthor primary healthcare provider as needed.
Laboratory Hazards
High energy-creating activities (centrifugation, sonication, high-pressure systems, vortexing, tube cap popping)
What is a biosafety level (BSL)?
A biosafety level ( BSL ), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility.
The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4).
What is Biosafety Level 1?
As the lowest of the four, biosafety level 1 applies to laboratory settings in which personnel work with low-risk microbes that pose little to no threat of infection in healthy adults.
An example of a microbe that is typically worked with at a BSL-1 is a nonpathogenic strain of E. coli.
