Biosafety Level 2 is appropriate for work involving agents that pose moderate hazards to personnel and the environment. In toxicology, this might involve handling certain chemical toxins and biological agents that can cause mild disease or are potentially hazardous. BSL-2 laboratories require limited access, biohazard warning signs, and the use of personal protective equipment (PPE) like gloves and lab coats. Procedures that may create infectious aerosols or splashes are conducted in biological safety cabinets.
