You know, Voyager had some weird situations with holodeck safeties. There was the episode Spirit Folk, where a holodeck control interface is shot by one of the Fair Haven villagers with his holographic rifle. The interface is damaged, followed by a warning from the computer that the safeties have been deactivated. If they were active beforehand, than presumably that holographic bullet should not have damaged the panel. In other discussions where this has been brought up, it's been said the safeties only prevent people from getting hurt, they do not prevent equipment from being damaged. Which is actually a very troubling idea, the device which is supposed to protect the users from being harmed by the program can itself be damaged by the program.
Then there's Pathfinder, where in an effort to get away from Commander Harkins and his security officers, Barclay goes into the Pathfinder facility's holodeck and activates a simulated Voyager, where simulations of the crew help defend him. Harkins goes and triggers a warp core breach to coerce Barclay into surrendering, which he does. The only way a warp core breach can be a credible threat to Barclay is if the safeties are off-line, but if that's the case, Harkins should really have gotten a good chewing out from his superiors for nearly setting off an antimatter explosion in the heart of San Francisco.
