Regulations Governing Management of Infectious Biological Materials Article 7

Animal biosafety laboratories, by their operational practices, barriers, and safety equipment and facilities, are classified into four animal biosafety levels (ABSL); the biosafety levels of laboratories and the infectious biological materials the laboratories may work with for animal experiments are as follows:1. Level 1 (ABSL-1): may work with infectious biological materials that usually do not affect human health.2. Level 2 (ABSL-2): may work with infectious biological materials that could affect human health, and for which preventive or therapeutic interventions are usually available.3. Level 3 (ABSL-3): may work with infectious biological materials that could produce serious effects on human health or may even be fatal, and for which preventive or therapeutic interventions are likely available.4. Level 4 (ABSL-4): may work with infectious biological materials that could produce serious effects on human health or may even be fatal, and for which preventive or therapeutic interventions are usually not available.
