What is the consequence of not posting proper signage on a domestic refrigerator in a lab?

Not posting proper signage on a domestic refrigerator in a lab can significantly increase the risks related to the storage of flammable substances. Proper signage is crucial in laboratory settings as it serves as a communication tool, alerting personnel to the hazards associated with the materials being stored. When a refrigerator is used to store flammable substances, clear labeling is necessary to ensure safe practices.

Without adequate signage, there could be a lack of awareness regarding the contents, leading to improper handling or accidental exposure to ignition sources. This can create an unsafe environment where flammable vapors might ignite, causing fires or explosions. Therefore, effective signage plays a vital role in minimizing these hazards by reminding personnel to observe safety protocols when interacting with equipment containing potentially dangerous materials.
