As long as it doesn't hamper firemen in case of fire, but they usually wear rubber gloves or similar protection...
I have a similar "trap" on an internal safe, but the standards say that home invaders, all wear surgical gloves or similar for "fingerprints"....
So I'm not too sure these ideas are good, since their is a chance of your forgetfulness, and a linked light will act as your warning sign.

In a home invasion, Cops usually tie your door knob so YOU can't open the door, unless they are in a hurry, and use their vast array of "breacher" tools......
The kicker on this is that most Cop Home Invasions are the *wrong* Address, and some Swat guy get's shocked or shot...

I just use household AC light current with a warning light and a reliable o/i switch.....I'm not sure if it's worth the hassle but it may be, better than nothing?
