Answer 1

To safely fuel a vehicle containing hazardous materials, it is important to ensure proper grounding, avoid smoking or open flames, and keep the nozzle in contact with the fuel tank.

Step-by-step explanation:

When a vehicle containing hazardous materials is being fueled, the following precautions should be taken:

1. Ensure proper grounding of the vehicle to prevent static electricity buildup, which could ignite flammable vapors.
2. Avoid smoking or open flames in the vicinity of the fueling process to minimize the risk of ignition.
3. Keep the nozzle in contact with the fuel tank to prevent static discharge and reduce the chance of a spark.

By following these safety measures, the risk of accidents or fires during the fueling process can be significantly reduced.
