no it is not
I second the statement. NEVER use graphite on a combination lock on a safe.
If your dial is hard to turn, you most likely have an internal mechanical problem -
be smart and call a safe tech. or locksmith for pricing to get the problem fixed
now - before it becomes an expensive problem.
what up habablablu invented the telephone. you had a detention tomorrow.
No. Graphite is a solid, not a gas and is safe enough for everyday use in pencils.
The material that made pencil to write is a mixture of graphite.
The structure of graphite accounts for the design of graphite electrodes in the sense that the tight structural composition of graphite makes it easy for them to be arranged in electrodes.
Graphite has an extremely low reactivity. Graphite can react with oxygen and sulfuric acid.
Graphite is pure carbon. A diamond is also pure carbon in a very specific crystal. Yet diamonds do not conduct electricity and graphite does. Graphite can form in plate like arrays of hexagonal crystals and in an amorphous, powdery form.
Yes, because pencil lead is actually graphite. It's very safe to touch, so, don't worry.
use a good graphite powder

Graphite is considered non-toxic and environmentally safe. That's not saying that you should be eating it! :)
Either replace the lock or disassemble it for manual repair.
Try graphite or lock lubricant
Try graphite powder
The key or lock may be worn out or it may just need lubrication. Spray powdered graphite into the lock cylinder. Do not use WD40. You can buy a tube of powdered graphite at any hobby store and WalMart.
I had luck using a lock graphite spray direclty into the lock and then inserting the lock and slightly during the wheel over and over again. Lock was "dry". Insert key and try to turn it. Do this over and over again. Put some graphite on the key and insert. Wiggle wheel. Eventually my key turned and that was almost 2 years ago and no problem since. If you use too much graphite, key will come out of lock black and so you will need to wipe off excess, if any.
A combination lock box is very safe for protecting goods. However, it depends on the type of lock, the type of material that the box is made from in order to determine how safe it is.
The bicycle lock would be a good place to use graphite ***** Graphite grease is usually used on the chain of a bicycle and on the ballbearing-races, as found in the wheels, pedals and bottom bracket, etc.
A safe state isn't a dead lock state. The state which doesn't lead to deadlock is termed as safe state.
