What signage must be displayed on a domestic refrigerator used in a lab?

The requirement for specific signage on a domestic refrigerator used in a laboratory setting is critical for ensuring safety and preventing dangerous situations. The correct choice to indicate the proper use of the refrigerator is that it should display a warning against storing flammable solvents.

Laboratories often deal with various flammable materials, and if these solvents were improperly stored in a typical refrigerator, it could create a fire hazard due to potential ignition sources within the appliance. This signage serves as a clear reminder to all laboratory personnel to avoid using the refrigerator for flammable solvents and to adopt safer storage practices.

Effective labeling not only communicates the dangers but also reinforces safety protocols in an environment where chemical handling is routine. By discouraging the storage of flammable solvents, the risk of accidental fires and chemical spills is significantly reduced, thereby promoting a safer workplace.
