You are hauling a shipment placarded for Class 2 gases. What should you keep in mind about this class?

Pick an answer

1. All Class 2 gases behave identically in every situation, so knowing the class alone tells you everything you need for safe handling every time, even though it runs against what the CDL manual actually says
2. Gases can be flammable, toxic, or under high pressure, so the specific material's properties still need to be checked, not assumed from the class alone
3. Gases are always safer to transport than liquids
4. Class 2 materials never require placards
