What is the purpose of spill containment in cylinder storage areas?

• A. To collect spills in a decorative tray
• B. To collect spills and prevent environmental contamination
• C. To block airflow
• D. To increase visibility of labels

Answer: (B)

Spill containment is there to capture any liquid leaks or vented refrigerant so it can’t spread through the storage area, protecting people, property, and the environment. In cylinder storage, leaks can come from damaged cylinders, faulty regulators, or valve leaks. Secondary containment—like pans, curbs, or a sump—keeps spilled liquid in a controlled area, making it easier to clean up before it reaches drains, soil, or water sources. This is especially important with flammable refrigerants, where spills or vapors can create fire hazards or exposure risks. It also reduces slipping hazards and helps responders manage a release quickly. The other options miss the point: a decorative tray isn’t about safety, blocking airflow would worsen risk, and simply increasing label visibility doesn’t address containment needs.
