Which container type is typically used for gases in HazMat transport?

• A. Carboy
• B. Cylinder
• C. Drum
• D. IBC Tote

Answer: (B)

Gases in HazMat transport are kept in containers that can safely withstand internal pressure and allow for controlled release. Cylinders are designed exactly for this purpose: they are rigid, high-strength vessels made to hold compressed gas, equipped with a valve and a pressure-relief device, and built to meet DOT/UN standards. Their standardized size, strong construction, and secure valve fittings make them the practical and typical choice for transporting gases. Other container types shown are intended for liquids or solids and aren’t suited to containing pressurized gas reliably—carboys are fragile containers for liquids, drums are for liquids or solids, and IBC totes are large bulk containers not designed for gas pressure. For cryogenic or liquefied gases, specialized dewars are used instead, but for everyday gas transport, cylinders are the standard.
