Help Jump on tightened/untightened sand

[ArtsyDrawer]

After doing some reading, I've settled on the SN DSMO method with a 25 hour antiemetic schedule.
I want to add some extra oomph just in case: climbing on a crane that is roughly 25 floors high and position myself in such a manner that once I lose consciousness, I fall from it. The problem, as the title suggests, is that this crane is in a "new prime area". There's sand everywhere. Some is tight from cars driving on it, some isn't.
That's assuming the back of it is positioned at the sand area.
Another option, depending on the crane's position, is to fall into the construction area, which is full of random, but solid grap. Might bash on something like 10 meters from the ground. Will the SN DSMO have less effect when combined with being splattered (hopefully) on the ground?

This is a lot...

Wow. This makes me think of @therhydler suggestion of drinking N while hanging and dangling over a cliff - just to be on the safe side.

I think tbh the SN should be fine on its own without the crane

Hitting water when you fall is like hitting cement, the sand should be hard in comparison to that, you'll die if you fall from 25 stories into sand.

I think there's no such thing as being too safe in this regard. If I'm "saved" from the jump, I've read some people describing being saved from a jump alone. Haven't seen any from SN, but as I said, I'm scared of being saved.
