Petzl has a specific warning on their website that certain models of the Grigri belay device can potentially fail if they receive a large load from below. Admittedly this would be a very unusual situation, but there are some cases when it could happen.
Here's a video clip made by Kevin Govan showing the mechanism of failure.
(Actual fail happens about 2:00.)
See a longer article on this topic and said the exact warning from Petzl at this link: www.alpinesavv....

It has happened to me while I was setting in my home gym, thankfully, the rope didn't slide out, it passed behind the notch but stayed (I don't know how) engaged (also, I had knots tied under me, even if it slept, it would have stopped) but that was pretty scary ( I apologize in advance if my English is not perfect)

Your English is perfect, thanks for sharing your story. That does sound a little scary.

why would you give a firemans belay w a grigri lmao

@lebulba 8 месяцев назад

not the point. its not impossible for something else to weight the break strand in a bazaar scenario. still good to know nontheless

How about the person rappelling has a problem, and someone on the ground decides to ascend the rope to help them. That effectively is a firefighter belay, and that could potentially cause a failure. Doesn't matter what you call it.

The grigri is clearly an excellent tool for use in mountain terrain and when used properly and with respect to its known failure modes is extremely safe....but the problem with moving parts is that they introduce a wider spectrum of configurations over which new failure modes can creep in. That is the trade off for devices of this kind. Personally, I do not love the feel of a grigri enough to carry one but I am not dogmatic about it. The added benefit of my abstention is that I don't really need to keep track of all these kinds of dangers. I really appreciate the clarity of this video. Thank you for posting it!

😳 great video

I imagine this becomes more likely the older and more worn the Grigri is?

Don’t have that issue with grigri 2

If you completely misuse the device with a rope that’s too skinny the device can fail? Who would’ve thought

This was done to illustrate the principle. Petzl clearly warns against doing this on their website. You can do it with a larger rope but it's difficult to film solo.
