To prevent the explosion of rocket upper stages, they must be passivated after payload separation. Upper stages of US-Delta rockets, for instance, perform an idle burn, while European Ariane and Japanese H-1 stages perform a venting operation to release remnant fuel. Likewise, also batteries should be discharged, and pyro devices should be deactivated at mission completion.
