Which of the following practices is important in a BSL-2 laboratory?

In a BSL-2 laboratory, the safety practices are crucial when handling moderate-risk agents that can cause disease in humans. These agents may be particularly hazardous through ingestion or mucous membrane exposure. Therefore, following specific safety practices, such as using personal protective equipment, proper waste disposal methods, and adhering to protocols for decontaminating work surfaces, is essential to minimize risk and ensure a safe working environment.

The focus on safety practices helps protect laboratory personnel, the surrounding community, and the environment from potential contamination or exposure. This includes using biosafety cabinets when necessary and ensuring that all individuals in the lab are trained in recognizing and responding to biological hazards.

In contrast, working without protective gear, using only basic laboratory equipment, or conducting experiments in open environments would significantly increase the risk of exposure and are not aligned with the safety standards established for BSL-2 facilities. Each of these incorrect options compromises safety and does not adhere to the necessary protocols that BSL-2 standards demand.
