When working with genetically modified materials, what biosafety practices must be utilized?

When working with genetically modified materials, the appropriate biosafety practices involve implementing BSL 2 practices. BSL, or Biosafety Level, refers to a set of containment protocols designed to protect laboratory personnel, the surrounding environment, and the public from exposure to infectious agents or biohazards.

BSL 2 practices are specifically tailored for working with moderate-risk agents that can cause human disease through exposure via ingestion or mucous membranes, indicating that there is a potential for harmful effects. Genetically modified organisms often have unknown effects, therefore the enhanced precautions of BSL 2 are vital. These practices include using personal protective equipment (PPE) such as gloves, lab coats, and face protection, as well as employing safety cabinets when necessary to prevent exposure and contact.

Conversely, BSL 1 is suited for work with well-characterized agents not known to consistently cause disease in healthy adults, while BSL 3 involves working with potentially lethal pathogens that may be transmitted through the air. Since genetically modified materials often require more stringent containment than BSL 1 while not reaching the level of BSL 3, BSL 2 is the ideal classification.
