What should be ensured when refueling a machine?

1. No open flames within 25 feet

2. A fire extinguisher nearby

3. Grounding the nozzle before refueling

4. All of the above

The correct answer is: All of the above

Ensuring all safety measures are in place when refueling a machine is crucial to prevent accidents and injuries. The correct response includes all mentioned practices because each plays a critical role in safety during the refueling process. Firstly, having no open flames within a certain distance is vital because fuels are highly flammable and can ignite if exposed to any source of ignition. Keeping that distance safe can significantly reduce the risk of fire or explosion. Secondly, having a fire extinguisher nearby is equally important. In the event of an emergency, immediate access to a fire extinguisher can be the difference between a minor incident and a major disaster. It allows for prompt action to control or extinguish a fire, ensuring the safety of personnel and minimizing damage. Thirdly, grounding the nozzle before refueling helps prevent static electricity, which can cause sparks. Static buildup can occur during the transfer of fuel, and grounding the nozzle ensures that any static charge is discharged safely. In summary, all these precautions are necessary and interconnected to create a safe environment during refueling operations. It's not just about one measure, but the combination of all safety practices that helps to minimize risks effectively.
