Which of the following should you NOT use to store automotive fluids?

Open barrels should not be used to store automotive fluids because they expose the fluids to air, which increases the risk of contamination and evaporation. Additionally, storing these hazardous materials in open barrels can lead to spills and leaks, posing environmental hazards and health risks. Proper storage of automotive fluids is essential for safety and maintaining the quality of the fluids.

Sealed containers are ideal as they prevent contamination and evaporation, while locked cabinets provide a secure way to store hazardous materials, keeping them out of reach of unauthorized individuals. Glass bottles can be used for certain fluids, but they may not be suitable for all types due to the risk of breakage. However, the key point is that open barrels are not safe or appropriate for storing automotive fluids.
