Either side of the battery will disconnect it. I generally recommend the negative side be disconnected first. If you are using a metal tool and touch the negative terminal and the car at the same time nothing happens. If you touch your tool to the positive side and the car a short will occur, possibly resulting in a burn, and definitely a big spark. If the negative side is disconnected and the positive terminal is grounded nothing will happen.
