BSL-1

Definition

BSL-1 (Biosafety Level 1) is the lowest level of biosafety precautions suitable for work involving well-characterized agents not known to cause disease in healthy adults. It involves standard microbiological practices without the need for special equipment or facilities.

5 Must Know Facts For Your Next Test

1. BSL-1 laboratories are used for teaching and basic research activities.
2. Agents handled at BSL-1 include non-pathogenic E. coli and Bacillus subtilis.
3. Standard microbiological practices include handwashing, no eating/drinking in the lab, and decontaminating work surfaces.
4. Personal protective equipment (PPE) such as lab coats and gloves are recommended but not always mandatory at BSL-1.
5. BSL-1 labs do not require special containment equipment like biological safety cabinets.
