Answer:

To safely jump a dead battery, remove the jumper cables in reverse order starting with the negative cable grounded to the car, followed by the negative on the dead battery, and then the positive cables.

When jumping a dead battery, it is crucial to remove the jumper cables in the correct order to prevent any possible electric shock or damage to the electrical systems of either car. The correct order to remove the jumper cables is:

1. Negative cable from the surface that grounded the live battery (not attached directly to the battery terminal).
2. Negative cable from the dead battery.
3. Positive cable from the live battery.
4. Positive cable from the dead battery.

This order is critical because it minimizes the risk of a spark near the battery, which could ignite hydrogen gases present around the battery. Always ensure that the last connection made, typically the negative to a ground on the car with the dead battery, is the first to be disconnected, and follow through in reverse order of how they were connected.
