Default Do fuel shutoff levers have a safety lock?

Pretty basic question: do fuel shutoff levers in your typical Boeing product have some kind of lock that prevents a pilot from accidentally dropping something on them that would push them into a cutoff position while in flight?

I'm not sure what a pilot would drop on them - a stack of Jepps, or a latte cup, or maybe a roll of $100s from those huge salaries all pilots make.

I think you have to pull them out and then push em down to the CUT OFF position! kinda like the Landing Gear lever on an Arrow or a Seminole when you try to retract them.

You have to pull out a bit and down. If anything hits it hard enough on the correct angle.... Boooooooo booooo. whoosh.

Do the 73NG levers work the same way? They look more like levers than the switches on 57s and 67s.

I guess it's moot since I've never heard of any incident like that happening in the entire glorious history of shutoff levers, but I was curious.

Yes. They have to be pulled out of the detent to start. They also have to be pulled out of a detent to cutoff.
