Can I change the oil on ramps?

Excuse me, but I was wondering if you could clarify something for me regarding car maintenance. The paragraph mentions the phrase "Can I change the oil on ramps?" Now, I'm curious to know if this is a practical or even SAFE option for performing an oil change. Would changing the oil on ramps pose any potential risks or challenges compared to using a level, solid surface? Additionally, are there any specific ramps or equipment that would be recommended for such a task, or are there any safety precautions that one should take when attempting to change oil on ramps? Your insights would be greatly appreciated.
