In a laboratory, when should bench top shields be utilized?

Bench top shields are designed to provide an additional layer of protection in a laboratory setting, especially in relation to experiments that might produce aerosols. When conducting experiments that involve aerosols, tiny droplets or particles can become airborne and pose a risk of exposure to laboratory personnel. The use of bench top shields helps to contain these aerosols, preventing their dispersion into the laboratory environment. This is crucial not only for the safety of the individuals working in the lab but also for maintaining a clean and controlled experimental space.

In contrast, the other scenarios do not typically require the protective use of bench top shields. During routine cleaning or monitoring temperature, the main focus is not on preventing aerosol release or protecting against airborne contaminants. Similarly, while storing equipment may necessitate proper organization and safety measures, it does not directly involve the risks associated with aerosol production. Thus, the use of bench top shields is specifically appropriate in situations where aerosols are generated.
