Yes, but a unique sleep bomb with a secret formula may render ordinary gas mask useless. It would require a special type of a mask that requires the same secret technology used in making the bomb. This is where science , technology, and secracy should play a role to make one of a kind sleep bomb that is highly unique and therefore requires a very special mask or gear to stay gas proof....
