I agree, never go under the car with only jacks and jack stand. Put your tire under the car if you jack it up so if something fail, the tire serves as a safety mechanism. When you are on ramps, make sure you place a thick block of wood under one of the tire so the car will not roll. Alsways use hand brake. Remember, do this at your own risk and always think safety.
