For storage compliance, flammable liquids should be kept in which container?

• A. Plastic containers
• B. Metal containers
• C. Glass bottles
• D. Wooden crates

Answer: (B)

Storage of flammable liquids requires a container that minimizes ignition risk and prevents vapor buildup. Metal containers are preferred because metal is noncombustible and provides durable, tightly sealing containment. Many metal safety cans are specifically designed with self-closing lids, gaskets, and flame arrestors to vent vapors safely, helping meet safety standards and compliance. Other materials—plastic, glass, or wood—can be more prone to damage, leaks, cracking, static buildup, or absorption of solvents, making them less suitable for flammable liquids. So using metal containers aligns with safer, compliant storage.
