The answer
Answer: B. Do all you can to protect containers of hazardous materials. Hazard lights, open doors, air-line disconnection, lowered landing gear and removed keys do not secure the vehicle, so set the parking brake and make sure it will not move while the hazardous materials are handled.

The answer
Answer: D. Keep fire away and do not let people smoke nearby. Class 6, 7, 8 and 9 materials and non-flammable gases do not ignite so readily, whereas Class 1, Division 2.1 and Classes 3, 4 and 5 could burn or explode, so no smoking is allowed around them.
