Method How to best prevent injury when doing partial?

[obei]

Yo Im so much on this forum I am getting on everybodys nerves so tell me if Im getting annoying ig.
So my method is partial, I have the pull up bar on my door, ill buy 13mm thick rope 2 meters long, ill wait when Im home alone.
I already know a lot about this method but I wanna know if there is any way I can ensure I will die and not end up alive and with brain damage? Its what scares me the most, so like, is there any way to prevent that?

There are very few permanent complications in the hanging method.
But your fear of the method disappears when you plan it correctly and with certain death.

If you wanna be 100% certain that you will die you should go with full suspension bc once you kicked the chair there's no way back unless you'd be found within a few minutes. Imo partial has a high failure rate.
