What is the only way to identify inter-modal tank types (besides tube modules and cryogenic)?

• A. the label printed onto the tank
• B. the color of the paint
• C. the serial number plate
• D. the tank weight

Answer: (A)

When identifying inter-modal tanks, rely on the markings that are printed on the tank. The label is the standardized source of information about the tank type, contents, UN number, hazard classification, capacity, and approvals, so it directly communicates what the tank is and what it’s meant to carry. These markings follow universal standards, making them readable and trustworthy for everyone from handlers to inspectors and emergency responders. Colors aren’t reliable because paint schemes vary by operator and region and don’t consistently indicate tank type. The serial number plate helps you trace the specific unit’s history and maintenance, but it doesn’t tell you the tank type itself. Tank weight isn’t a dependable identifier either, since tare and loaded weights can vary and don’t reveal design or classification.
