I'm also a little scared of jack stands and will throw something extra under there like a spare tire or block of wood so the car won't fall all the way down. The reason I'm posting here though is to remember that batteries can be flammable too. I had always heard they could explode but was never too concerned about it. When I saw one blow up in my friends face, I have a new respect for hooking up booster cables. They can explode as loud as a gunshot and acid will spray everywhere. Sometimes when a battery is dying, it will start boiling and making a lot of gas. So beware when you are being a good Samaritan and boosting another car. Hook the ground up last and preferably to a bracket on the engine. I was always taught to hook up the dead battery last but I think it's safer to hook up the good battery last because there is less chance of encountering excess fumes with a good battery.
