Which container must be stored in different cabinets or in an isolated area?

The most appropriate choice is storing containers that hold 1 gallon or more in different cabinets or an isolated area. This is because larger volumes of potentially hazardous materials can pose a greater risk in terms of spills, leaks, or exposure to employees. Containers with 1 gallon or more of hazardous substances often include chemicals that may be flammable, corrosive, or toxic.

Storing these larger containers separately helps minimize the risk of accidents and ensures that any potential hazards are contained in a controlled environment. Additionally, following safety regulations and guidelines for the storage of larger quantities contributes to maintaining a safe work environment.

In contrast, containers that are 1 gallon or less generally present a reduced level of risk due to their smaller volume, and it is often acceptable to store them in the same area as non-hazardous materials, provided appropriate safety measures are still taken.
