Final answer:
Flammable or combustible liquids should not be stored in plastic containers. Metal, glass, and ceramic containers are more suitable for storing these liquids.
Step-by-step explanation:
Flammable or combustible liquids should not be stored in plastic containers. Plastic is generally not suitable for storing these types of liquids because they can react with the plastic and potentially cause it to degrade or release harmful chemicals. Metal, glass, and ceramic containers are more suitable for storing flammable or combustible liquids as they are less likely to react with the contents.
