There may be times when the Laboratory Director or Safety Officer determines that enhanced precautions or ‘BSL-3 practices’ (e.g., use of double gloves, solid front gown, or respiratory protection) are needed based on a risk assessment, such as:
- When working with organisms that may be transmitted by inhalation and are usually handled at BSL-3, but a BSL-3 laboratory is not readily available.
- When certain higher-risk organisms are suspected, such as Brucella spp., Coccidioides spp., Blastomyces dermatitidis, Francisella tularensis, Histoplasma capsulatum, Mycobacterium tuberculosis, MERS-CoV, SARS, highly pathogenic influenza, etc.
