In my work, developers only have read access to production servers (for checking logs etc). If you want to make a change to a production system, you need to go formally request it through OTRS. So this sort of situation can't really arise. You can of course still cock-up live systems through asking the sysadmins to do something stupid, but then the problem is stupidity, not carelessness.

P.S. You poor soul! I feel your pain.
