Final answer:
Only trained individuals are typically allowed to refuel a propane vehicle due to the potential hazards of handling propane, a highly flammable gas. Propane is also used as an alternative energy source in remote locations without natural gas infrastructure.
Step-by-step explanation:
The question regarding the refueling of a propane vehicle addresses safety and technical considerations that are essential to understand. It's false that anyone is allowed to refuel a propane vehicle. Just like any other fuel, propane requires proper handling to ensure safety. Individuals who refuel propane vehicles are normally required to have specific training to manage potential hazards associated with propane. This is due to propane being a highly flammable gas, and incorrect handling can result in dangerous situations.
Regarding remote locations, propane is indeed used as a substitute for natural gas. This is particularly true in areas where the infrastructure for natural gas pipelines does not exist. Propane is a flexible energy source and can be transported and stored relatively easily, making it a viable option for heating and energy needs in remote places.
